Torsion Box Improvement

Torsion Box (lightweight panel, sandwich panel, honeycomb panel)

1. What is Torsion Box?

The revolution or evolution of wood working, metal fabrication, plastic and cement meets the invention of patented Sing Sandwich core (see the many uses of Sing Core). Sing Panel provides the wood worker with pre-built torsion box.

Traditional torsion box (above) which could take all day to build

or insulated pre-built Sing reinforced torsion box (below)

2. Why Torsion Box?

Because other methods of building a table top are basically inefficient. For instance, a table top built of a solid material will shift and move over time compromising its degree of flatness. Also solid materials that are less likely to move are extremely expensive, heavy and would only be considered for a permanent fixture.

The torsion box table top design gives as flat a surface area as possible while reducing the weight of the table top due to the hollow areas in the center of the boxes. Using a torsion box design, a craftsman can build the most flat surface using 1/10th the solid material.

3. How does torsion box work?

aka: lightweight panel, sandwich panel, honeycomb panel

Examine the theory behind the torsion box/sandwich panel/lightweight panel/honeycomb panel

please click link below:

Sandwich Panel Core

Use Sing torsion box to replace conventional wood core, particle board core for the true flat, light weight and high strength characteristics.

There are several core materials also widely used to function as torsion box such as:

* Wood core
* Furniture wood core
* Table wood core
* Solid wood core
* Wood core table
* Wood core furniture
* Wood door core

Google Search: wood core

Why do craftsmen use wood core? Because it reduces the cost of exotic woods and by alternating grain orientation – like plywood – it can help to minimize warping; but even plywood warps and is very heavy. Using lightweight Sing torsion box may eliminate warping altogether.

* Sing torsion is 10% of the weight of solid wood based core.
* Sing torsion box is stronger than steel lbs for lbs.
* Sing torsion box is safe to work with
fewer injuries if the object is a large door
table or large piece of furniture.

Get your torsion box pre-built for you in 2 ft. x 4 ft. sections

Imagine being able to build a torsion box work table and hundreds of lightweight, high-strength true flat, non-warping panels – endless applications – without the time, energy and cost of building the torsion box yourself?

4. How to work with Sing torsion box

Just use your normal wood working tools and treat it just like you would solid wood core, particle board core (substrate) or any other core materials (lightweight core, sandwich core, honeycomb core). The best core (click here to see charts to compare) material at an affordable price.

Patented Sing Core supplies the military, high-end millworks, general contractors and architects across the USA (see clients list) with massive torsion box structural panels that are lightweight, stronger than steel pound for pound and perfect true flat –> click here <– to see premium Sing Panel for large door applications guaranteed to be true flat and stay flat for 50 years.

Solid wood and metal will move and adapt to temperature compromising the functionality and seal of the most elegant hand-crafted wood door. Diligent woodworkers have sought out Sing’s solution to the oversized wood door.

The same scientific solution of reinforced torsion box applies to tables and other structures that can be built without traditional wood framing for furniture or stick-built homes.

5. How to build with Sing torsion box

It’s easy to build your own products on demand, as you need it in any size you want.

This is the most popular in-house Sing technology used by craftsmen and millworks.

You might have never known how easy it is to build using this cold-press drop-in method.

How Easy Is It?

This is how simple it is to for you to use our pre-built torsion box.

All you have to do is to coat the underside of your bottom skin with regular carpenter glue…

Place your wood edges atop the glued-side of the skin…

Then fill the void with pre-built torsion box pieces until full.

Place glued top skin onto your completed work…

Finally cold-press until dry (those two pc of panels to hold the gluing object are made of Sing panel).

This simple cold press (above) is made of two pieces of Sing panel (one on the top and one on the bottom) and clamped together with pipe clamps.

It’s that easy: Congratulations; you just made your own insulated reinforced torsion box panel!

Oversize Entrance Pivot Doors

“If we could build this giant warp-free wooden pivot entry door, we can build your door.” ~ Peter Sing

For thousands of years pivot doors have been the upscale preference of the most exotic high-end large oversize entrance doors relying heavily on the entry door hardware, specifically the pivot hinge, to manage the functionality of the pivot door.

Due to the size and weight of the conventional modern pivot door the heavy duty hinges and pivot door hardware could account for up to half the cost of the pivot door (e.g., a low end pivot door could cost $3,000, half the price will pay for the hardware due to the heavy weight), creating a high price point as well as being expensive to transport, handle and install.

Yet, the most demanding clients desire this elegant outswing exterior door to make an extreme visual impact for the primary access point of their structure (while bringing the outside in and the inside out by way of the architect’s modern design concept) regardless of price to command attention via first impression.

Pivot doors may be the most expensive designer doors but there’s no escaping the luxurious feel that they lend to designs by top architects who help to create the most leading edge structure designs by featuring the best exterior doors.

Since hardware is of huge importance in a pivot door’s design and implementation, there are many options to consider including offset pivot hinge, commercial door hinges, heavy duty door hinges and center pivot door hardware in your pivoting door system.

Steel Pivot Doors

Many pivot doors feature metal structures and framed composites and more popular for exclusive high security environments, commercial steel entry doors and even residential steel entry doors.

How to Build an Exterior Door

Many considerations must go into the design, plan, building and installing a pivot door.

1. The Core Material
The core material that makes up the heart of your pivot door determines so much. Based on your choice of material you will determine your pivoting door’s:

Weight
Strength
Insulation
Precision
Performance
Maintenance

2. The Frame

Will your pivot door be a solid one-piece material construction, or will it be framed or unframed?

Many options about for the substance of your pivot door, first – the most heavy and likely the most unstable – is solid construction, then framing. Framing your pivot door can be with wood or metal, like steel or extruded aluminum. Wood will move framing with metals, like a conventional steel door, may not meet high performance specifications due to welding creating imperfections in the metals.

3. The Entry Door Styles

What will the general appearance of your door be? What exterior surface material, skin (see material options) or design will make your pivot front door stand out to make that impactful visual impression?

the best pivot full lite glass door high end pivot door beverly hills

4. Hardware

What hardware will be required (price is usually influenced by style of pivot and finished weight of door) for optimal performance of your pivot door?

5. Installation

Who will install your pivot door and will any special handling/equipment be required for installation?

Can the Affordable Pivot Door Replace Contemporary Entrance Doors?

Until now, pivot doors have generally been too expensive for the average homeowner to consider, but one pivot door core material is changing all that. Sing Core manufactures an Eco-friendly pivot door core material used by the most high-end architects, designers, door manufacturers, millworks and contractors for building the best pivot doors in the world.

What constitutes the best pivot door in the world? One that is:

1. Eco-friendly (sustainable, true green)

Sing Core panels are constructed with natural wood fiber vertical grain torsion box filled with recycled rigid foam adhered between stress skins using formaldehyde-free glue for a solid substrate.

2. Lightweight

Sing Core panels weigh a fraction of the weight of other solid structural building materials.

3. High strength

Sing Core panels were independently tested by the University of Washington at 660 PSI for super-strength (compared to 10 to 110 PSI of other honeycomb cores used in the aerospace industry).

4. Insulated

Sing Core panels are packed with insulation rated at R 3.5 to R 6.5 (depending on foam selection) and feature sound deadening qualities for security and privacy.

5. High Precision

Only Sing Core panels can be created to be true flat, within .006 inch tolerance with little or no deflection.

6. Versatile

Sing Core panels can feature any surface material (skin), like any wood species, aluminum, ceramic, concrete, fiberglass (FRP), HPL, Kevlar, LVL, MDF, stainless steel, stone or any other flat building material, may host any glass lite openings in any configuration and can be embellished to have the appearance of any style door imaginable.

7. Guaranteed not to fail

Only Sing Core’s professional pivot doors can be guaranteed true flat and to stay flat and not to fail for 50 years. (See free consultation).

Only by using patented Sing Core can any pivot door achieve such results.

Mirror with Sing Core inside = Unbreakable

How Can I Get a Sing Core Pivot Door?

There are many ways that you can make your pivot door dreams come true.

1 Architect

Architects have access to Sing Core technology and are specifying Sing Core in their pivot door designs – especially if they are large pivot doors – that can be manufactured by their favorite millworks.

2 Millworks

Most one-of-a-kind custom pivot doors are created by revered craftspeople and woodworkers who create hand crafted pivot doors for exclusive clientele.

3 Door Companies

Any door company can use Sing Core panel as the substrate for your pivot door. Though many do not feature the Sing Core pivot door as a standards catalog item, in most cases you can special order your pivot door with Sing Core technology.

4 Contractor

Sing Core pivot doors panels are sold without hardware installed and unfinished. Our door panels are manufactured for mill works to install hardware and finish. We do not recommend shipping Sing Core door panels the job site for installing hardware and finishing. This is not the best way to treat a high end door such as a large pivot door made with Sing Core. We highly recommend the GC work with millwork professionals to finish at their facility (except some special restrictions).

We believe each professional has it’s own specialized knowledge just like we do not expect an architect to install the door, instead using a highly trained GC.

Since the weight of your Sing Core pivot door will be a fraction the weight of a solid (or framed) pivot door you can save cash that would have to be invested in heavy duty pivot door hardware that could account for half the cost of any other pivot door.

Plus you save on transportation and installation costs, just like our clients (see clients list) and enjoy maintenance-free high performance of your pivot door.

How to Fix a Warped Door

Many people struggle with how to fix a warped door. Nothing is more frustrating than spending your hard-earned money on a nice door, only to have it warp, bend, twist or cup not long after installation.

This problem is magnified exponentially especially if the door is a large oversized door. Some of these high-end large doors can cost tens of thousands of dollars only to discover failure due to warp when the season changes. This can mean job security for door repair services, millworks and contractors serving the account, but can lead to dissatisfaction and frustration for the client.

Patented Sing Core

Dealing with how to fix warped wood doors is considered standard maintenance for high-end applications; that was until the invention of patented Sing Core. Only large oversized wood doors made of Sing Core can be guaranteed true flat – and to stay flat – for 50 years. See: No More warped Doors.

Sing Core solves the issues with warping and eliminates the mystery of the warping door. By integrating Sing Core into your door’s composition you can have an elegant, maintenance-free long-lasting door that will not warp, bend, twist or fail regardless of size or application.

Free Door Consultation

The most prestigious clientele around the world seek out expensive door professionals (Certified Door Consultants) to help design doors that meet or exceed the performance standards. We provide free large door consultation to trade professionals to assure that the door that your client receives delivers the high precision performance that they expect.

Click here to see how patented Sing Core door planks/panels/blanks are made providing the only 50 year non-warping guarantee.

Demystifying Door Warping

There is no longer any need to be frightened of doors warping, due to our extensive experience in providing doors (even huge, enormous doors) that are guaranteed not to warp for 50 years to the most proficient building designers, contractors, mill works and high end door manufacturers.

The biggest problem for doors is warping (especially in large doors) used n high-end home building projects and commercial projects when building sliding doors, pivot doors and big interior doors.

Most door manufacturers and millworks avoid building doors over 8 feet tall or offer a very limited one year warranty with many exclusions/restrictions to prevent exposure to damages due to warping. Click here to see

When you buy your door, and even following installation, it may or may not be flat. Most doors begin to shift and move following manufacture. By the time your door arrives at the job site, it may already be warped or beginning to experience separation between the exterior surfaces and the core material.

Certainly after years of regular use (paper core, foam core) will warp and/or delaminate.

No matter what kind of standard core a door is made from, whether paper core, foam core, SLC (Stave lumber core), particleboard, SCLS (Structure composite lumber), LVL (Laminated veneer), mineral core, MDF, cardboard, etc… warping is inevitable. Even a solid wood door will warp. A sliding or pivot door will have unbearable warp at only ¼ inch due to the reference next to a straight wall or door jam. This warping is even worse in a door over 8 feet because of the strength of the movement. So far, the best solutions have been to only make 7-foot high doors, or to make excuses (i.e., no or very limited warrantees) for doors over 8 feet, or to use gaskets to hide the minor warping, but these are temporary solutions that require costly maintenance and replacement and tarnish the reputations of the building trade professionals involved in the projects. As such, most doors usually do not have warranty protection against the inevitable warping. Even with SCLC (Structure composite lumber core) and LVL (Laminated veneer), commonly used in high end large door will not remain true flat due to the wood fiber constantly moving.

Finally, Sing Core provides a guaranteed solution to the challenges of warped doors and it is the only affordable lightweight high strength solution that can provide 50 years of high performance, remaining straight and true without fail. Plus, Sing Core offers insulation qualities that cannot be found in other strong (heavy) building materials. Only this unique patented torsion box/rigid foam composite can offer the superior strength – bridging long spans, or towering heights – while insulating and providing sound deadening benefits.

Sing Core helps door manufacturers and mill workers build doors which satisfy even the most challenging high-end door market. (Click here to see our client list.) Doors made with our patented Sing core panels are true flat and may be guaranteed to stay true flat for 50 years. In addition, our patented Sing Panels (door blanks) are:

1. Dimensionally stable with a high precision tolerance of +/- .006 inch. This is laser precision which produces the smoothest and most true-flat panels.
2. Fully insulated for temperature control and sound-deadening qualities and which are 3 to 5 times more insulated than solid wood-based door cores.
3. Lightweight so that even a 4 inch thick door will weigh only 2 to 3 pounds per square foot. An average wood-core weighs 8 to 10 times more than our patented Sing core.
4. High strength which has been verified by the University of Washington at above 660 PSI, making our Sing panels pound-for-pound stronger than steel. (You could drive a 12,000-pound forklift over them without crushing them!)
5. Water-resistance/waterproof doors made of patented Sing core panels can be completely exposed to the weather without warping. (Click here to see our exterior door gallery.)
6. Eco-friendly and non-toxic structure glue for bonding skins and Sing core.

High Precision Doors

Sing High Precision Doors are a marked improvement in door development, design and implementation thanks to a newly invented Eco-friendly core material that is lightweight, insulated and stronger than steel pound for pound.

This new technology is revolutionizing the door industry especially in regards to large oversize doors. Architects, designers, mill works and door manufacturers all experience problems with doors that are larger than normal size.

Large doors present a variety of challenges in areas, like:

choice of available materials
lightweight doors are weak and tend to fail
heavy doors strain hardware and structure
increased regular maintenance
failure due to warping

Sing High Precision Doors solve all these issues with an Eco-friendly insulated solution.

How high precision are Sing High Precision Doors?

Sing High Precision doors are created with so much accuracy that the original door slabs are perfectly flat within .0006 inch accuracy.

After applying your desired composite materials and/or skin, your high precision door can be laser CNC machined for a perfectly flat surface, limited only by the accuracy of your CNC machine shop capabilities.

The Large Challenge

Certainly, you could use laser CNC cutting and engraving to machine nearly any door made of almost any commonly used door material for a flat result. The challenge comes from standing the door upright and expecting a degree of effective usefulness over time.

Why Large Doors Fail

The effects of gravity, varying degrees of moisture and/or atmospheric change, and the natural limitations of the characteristics of the building materials that comprise the door all contribute to its failure. This causes dissatisfaction for the end user, who has invested a great deal of expense in the design, manufacture and installation of this specialty large door.

Door warping is the number one problem for oversized doors that are otherwise enjoyed by the most discriminating end users.

The Disappointment

No one wants to spend that kind of money on a door that is going to warp, bend, twist, delaminate or compromise the structure or hardware with normal recommended use.

Now, here’s the exciting part…

Sing High Precision Doors can be guaranteed not to warp, bend twist or otherwise fail for 50 years!

Imagine having a large door that can be installed that will not pave the way for repeated service calls over the life of the door.

Take a look at some of our clients who trust us with those difficult door challenges because they are the most reputable high performers in the industry who only deliver the highest marks in terms of customer satisfaction, especially now that they can deliver a fail-free large door that will not cause frustration for their client’s or their service departments. See clients List.

Highest Precision in Doors

Click Image for True Flat

No other building material can be guaranteed to maintain a true flat surface and milled with laser precision for long-term maintenance-free performance for 50 years. This is why you can find the growing demand for the Sing solution from beneath the sea (US Navy) to outer space (NASA) and everywhere in between.

The high precision Sing solution is not just for doors; turned flat these very same Sing Panels can become floors, tables, counter tops, ceilings and roofs. Turned on their sides, these patented panels become walls, moveable partitions or virtually any other type of application.

Solid Wood Stave Door Blanks

Applications -> Building Components -> Doors -> Solid Wood Blank Doors

solid wood stave sliding door wood planks composite honeycomb panels

Click on picture to see our wood skin gallery!

Our panels make doors!

Patented Sing Core solid wood stave door blanks feature the newest technology in the door industry for composite doors yielding the only eco-friendly, lightweight, fully insulated, high-strength doors with wood blanks of any size (up to 40 ft.) that can be guaranteed true flat and to stay flat for 50 years.

Large door versus regular-size door challenge (i.e., over 4 feet wide and over 8 feet in length):

Large doors are heavy, dimensionally unstable, require more strength due to the heavy weight, and are a challenge to manufacture, ship and install. High-end jobs require precision and true flatness to please the customer. A homeowner’s architect, general contractor and mill worker must solve the problem of warping doors. The solution to the challenge is to use patented professional true flat Sing panels to make your doors.

Sing Core wood stave door planks are the only solid wood doors that will not warp, bend, twist or cup following installation. This means no more continuous service calls for maintenance of big doors that cannot possibly stay straight due to the limitations of solid wood – or any other door core – that is subject to failure. Sing panels have a patented honeycomb/torsion box interior which gives lightweight yet unsurpassed strength (pound-per-pound stronger than steel) and stability to any door, and allows Sing Core to provide a 50-year guarantee

Interior Doors:

Sing panels make amazing designer doors in any style. With Sing panels, fragile doors such as French doors are made lightweight yet strong, not warping or breaking hinges, which will last for many decades.

Exterior Doors:

Sing panels make sturdy exterior doors in any style. With Sing panels, exterior doors are lightweight and strong, even when oversized. Our professional doors are guaranteed to stay true flat and not warp or twist for 50 years

When is a door not a door? When it fails to function as a door.

The problem is that all door core materials are either not high precision, too heavy or will move when exposed to moisture, humidity or change in temperature resulting in door failure.

Heavy solid metal or steel will not warp, bend or twist, but is not high precision due to welding (sing core tolerance is + or – .006 inch!) and is often impractical due to the overweight issues causing excess strain on both the hardware and structure, causing continued maintenance issues. The solution is our patented lightweight yet strong Sing core technology.

Finishing a door blank:

There are two types of finish for door blanks: paint grade and wood grain. Paint grade includes such finishes as metal, Masonite, marine plywood, etc. Wood grain finish includes such finish as solid wood stave and thin veneer.

Why Use Solid Wood Instead of Veneer?

Never settle for substandard veneer doors again. Door engineers prefer to use inexpensive veneer as opposed to real solid wood facings because veneer is thought to be less likely to warp, bend or twist. But thanks to the super-strength of patented Sing Core technology, you can use solid wood stave and wood blanks with confidence knowing that your door can be guaranteed true flat and will stay flat.

How can a solid wood-faced door stay true flat? As every woodworker knows, when using a solid wood surface, the grain will move according to moisture or temperature change causing the door to fail. When using our patented Sing Core as a substrate you can safely use solid wood because the solid torsion box/honeycomb patented material is continually keeping the wood grain straight and true. Whereas wood stave has more wood fiber giving it more of a chance to warp than thin veneer due to the unbalance of the both side of the door moisture contents, patented Sing technology solves this problem by combining stiffing skin on both side of our patented Sing core. This Sing panel technology eliminates the troublesome movement of the door blank — warping is no longer a concern when wood stave is combined with patented Sing core.

In addition, solid wood is easy to work with, install (no need to hot press), repair and remodel. That’s why professionals trust Sing Core’s years of expertise in helping to design the only wood stave doors (that look just like solid wood doors) that can stay straight and true for many decades while respectfully honoring the beauty and elegance of solid wood, which far outlasts easily-damaged veneers, yet can be sanded and repaired if necessary.

Celebrate your real wood!

Our Eco-friendly lightweight, high strength alternative is the best solution for combating the issues associated with weight and size, especially large doors. Only our patented Sing torsion box/foam composite core combined with our years of experience provides guaranteed solutions for oversize doors.

That’s why this technology is found everywhere, from beneath the sea (US Navy) to outer space (NASA) and everywhere in-between.

Sing panels may be finished in almost any wood species, like mahogany, redwood, teak wood, cherry wood, walnut wood, cedar wood, Ipe wood, sapele wood, poplar wood, ebony wood, ash wood, oak or any other hardwood or exotic wood types available.

This same wood blank composite technology is also a common solution for high-end projects like engineered hardwood flooring, shiplap, wood furniture, wood shelves, decking, shed doors or any other application demanding high precision and exemplary performance over time.

How is wood stave/veneer added to Sing panels?

Wood stave is added directly to the metal or wood skin our patented Sing cores. Wood veneer is added to an 1/8-inch mdf attached to the metal skin.

Aloha from Honolulu, Hawaii, where Professional Sing non-warping doors are making an impact.

Hawaiian door manufacturer sought out Sing Core in search of a non-warping exterior door solution for rigorous climate variances especially large oversized sliding doors and pivot doors.

During the free consultation, the manufacturer explains that large doors are known for warping top to bottom, but people don’t talk much about warping side-to-side, which makes it a constant struggle for latching and sealing the door. These are the constant issues that face the makers of large exterior doors.

The specifications for the door included a natural Sapele wood stave exterior which complicates the door project even more because the innate natural wood grain will have a tendency to warp, bend and twist according to changes in temperature and humidity.

Door manufacturers find it hard to believe that inventor Peter Sing would be willing to, “put his neck out on the line for 50 years.” It is this 50 year non-warp and structure guarantee that intrigues manufacturers of larger doors, especially if the door specs include exposed solid wood.

The undeniable fact is, patented Professional Sing Core is the only way to build a lightweight, high strength non-warp door. And Sing Doors are guaranteed not to warp – top-to-bottom or side-to-side – for 50 years including full structure guaranteed also.

We are the best door substrate for doors, not just in the continental USA, where we are best-known but also in Alaska and Hawaii, when it comes to the most prestigious big doors.

Here’s an example of a 98” x 84” x 3” Professional Sing Door with custom lite cutouts for a modern pivot door presentation and 1/8” Sapele wood stave exterior, weighing in at only 250 lbs.

Overhead Door vs New Garage Door

If you are in the business of overhead garage door or any type of door business then this new garage door is an opportunity for you. The reward can be win-win for you and your customer.

The problem for overhead door and traditional carriage doors vs. Sing garage panel door

Everybody wins by switching to patented Sing Core.

The trend is 90% or more or garage doors are light duty metal or vinyl overhead doors. Traditional carriage doors cost at least 4 times more than those metal or vinyl garage doors. Now the patented Sing panel garage door with its small price tag and endless features for your customer means the end user gets a better product for less money.

The 7 Wonders of Sing Garage Panel Door are:

Price. Sing Core panels cost about 87% less than carriage doors, yet comparable to inexpensive overhead doors in price.
Insulation. Pre-insulated Sing garage door panels protect you from the elements and are sound-deadening.
Air tight. Sing garage door panel maintain their seal because they are resistant to warp, bend and twisting.
Lightweight. You don’t need expensive heavy duty hardware because they weigh one-fifth the weight of traditional carriage doors.
Strength. Compared to other composite core materials (that range from 10-to-100 PSI) Sing garage panels weight in at 660 PSI (stronger than steel pound for pound.
Low maintenance. Because they are lighter in weight and do not warp, bend and twist, you don’t have to worry about garage door repairs.
Security. Your new design (if based on carriage door design) is harder to breach than simple overhead door design.

Overhead door

The overhead door is so popular due to mass production with thin gauge metal at low cost, even so we see many overhead door companies utilizing the Sing solution in their designs.

This is what most of American homeowners are looking for even it is easy to dent. If you use your garage as a shop or living space it has little or no insulation. Even if it is well insulated overhead, there’s virtually no way to make it air tight like carriage door. The good news is the sing carriage door is low cost and can be the new standard of garage door.

The revolutionary solution for overhead door.

Carriage door

The carriage door is the way American home’s garages used to be made before overhead doors become popular. But due to the high price, heavy weight and not being insulated well and warping leading to air and temperature leaks – especially in the winter due to the movement of the wood (low temperatures made wood carriage doors shrink and summer heat make the doors expand).

The biggest concern about carriage doors is that they are too expensive. You could spend over $4,000.00 for a 8 ft x 7 ft carriage door and over $8,000 for a 16 ft opening garage door, but none of those framed carriage doors will be easy to install due to the heavy weight and if they’re not perfectly straight. If it warps then it will leak the air and many times even otherwise adequate gaskets cannot stop the air leak.

Sing Panel Garage Door

For garage dealer or distributor:

High profit margin (selling one set of Sing carriage doors will make more money than selling 6 overhead doors, still making the customer happy, because they will have paid less than half of the traditional carriage door).

For garage door manufacturers

You will love to Sing… We will supply you the Sing Core to build better, stronger, lightweight garage doors. Sing Core is available at low price if you could order by the truck load – or even better – we might be licensing to you to build garage doors out of Sing Core.
