Hot Rolled Steel Doors
Sing Core brings an Eco-friendly approach to working with large spans of hot rolled steel with less weight and more strength than plain steel pound for pound, revolutionizing the steel fabrication process. In fact, we are best known for our large hot rolled steel metal doors and hot rolled steel wall panels.
Our patented rolled steel panels feature custom metal fabrication uses high grade formaldehyde free adhesives instead of the more destructive welding process and your Sing Hot Rolled Steel Panel can host an exterior hot rolled sheet metal thickness of 16 gauge or more.
Sing hot rolled steel takes metal working into a whole new arena that is being embraced by steel companies making huge hot rolled steel products without having to use heavy steel framing.
One of the primary functions of Sing hot rolled steel products is in the area of commercial steel entry doors. If you are new to metal manufacturing, you will find that raw hot rolled steel has a more primitive or industrial feel to it, it has a less smooth surface than cold rolled steel and requires finishing to avoid rust or oxidation. The unique appearance of hot rolled steel panels appeals to designers, architects, museums, art galleries and often used in steel wall art.
Especially if you’re considering utilizing hot rolled steel for your large doors, Sing Core can help to mitigate the damages caused by the heavy weight of hot rolled steel doors with interior steel frames that require welding. This allows you to build hot rolled steel doors of immense size that are high precision, just like other types of Sing metal.
The Sing Core material is extremely high precision (within +/- .006 inch) which keeps your hot rolled steel door straight and flat regardless of its size. The advantages of the straighter and truer big metal doors come in handy when you multiply the door’s required integrity by two when dealing with steel double doors. Double steel doors, especially if they are large and oversized, are fraught with additional challenges.
Sing hot rolled steel can be used for upscale industrial steel doors and in commercial metal door replacements for increased performance and high precision which also supply the project with built in insulation and sound deadening qualities.
Our hot roll steel solutions are changing the scope of architectural metal fabrication because the nature of hot rolled steel is predominantly restrictive due to the weight and framing required to support the raw material. Having access to a lightweight, high strength alternative, like Sing Hot Rolled Steel Panels, opens doors to unencumbered creativity.
Sing Core’s hot rolled steel doors are just some of the best doors that are among the many types of doors that have put us on the map as the best door featured in the most high end jobs across the country and the world.
You will find Sing hot rolled steel panels used not only as a standard swing door but also as hot rolled steel flooring, hot rolled steel counter tops, hot rolled steel wall panels and room dividers, hot rolled steel pivot doors and hot rolled steel sliding doors.
Let Sing hot rolled steel set your creativity free. See also: Steel Fabrication

Wide Doors for Hinge or Pivot Door Hardware
Exclusive to multimillion dollar spec homes, the standard extra wide exterior doors are pivot doors to accommodate the unique challenges of wide doors.
The Problem
Wide doors will warp, not just top to bottom but side to side which compromises the seal and creates a problem for latching the door. Wide doors are problematic due to warping requiring regular maintenance to adjust the wide door accordingly.
The Solution
The Sing non-warping Professional Pivot Door Panels are the solution because if the door does not warp, you’ve solved the problem with the failure of wide doors altogether, and can be guaranteed to remain non-warp for 50 years. Even $10,000 wide doors cannot be guaranteed not to warp; even for one day.

This wide door could use concealed door hinges as swing door hinges or pivot door hardware for extra wide exterior doors thanks to Sing Core.
Advantages
Using the Sing non-warp door blank as the basis extra wide exterior doors used in multimillion dollar spec homes is not only the only solution, but also imbues your door with the following benefits:
- Lightweight: Sing wide door blanks are 17% the weight of other solid wide wooden doors, i.e. 120 lbs. vs. 720 lbs. at 4 ft. wide door.
- High Strength: Sing wide door blanks are stronger than steel pound-for-pound (660 PSI).
- Insulated: Sing wide door blanks are packed with rigid foam insulation rated at R3.5 per inch at no extra charge for heating/cooling control as well as sound dampening.
- Non-warp: Only Sing wide door blanks can be guaranteed not to warp, bend or twist –including full structure integrity – for 50 years.
Affordable Wide Doors
Expensive pivot doors start at about $10,000 and just the hardware (due to the heavy weight of the door) can run into thousands of dollars and requires highly skilled craftsmen to install/maintain.
Sing wide door are a fraction of the weight and price of extra wide exterior doors. Due to being so lightweight, less expensive pivot door hardware can be used. In fact because Sing wide doors are so light in weight, you can even use standard hinge door hardware. This is why Sing wide door blanks are the premium choice of high end carriage door manufacturers.
Now, wide doors need not be relegated only to million dollar homes, because making them more affordable puts them within the reach of discriminating home owners who would like to increase the impact of their entrance door by switching to an extra wide front door.
Retro-fit Wide Doors
Say, “goodbye,” to sidelites. Sing wide doors can easily be retro-fitted to replace a standard existing exterior front door and sidelites with a single Sing extra wide front door using your choice of side hinges or pivot door hardware.
Sing Wide Doors Always Latch
The difference between sing wide doors and any other extra wide door is that you can always count on one thing: Sing wide doors will always secure and latch every time because they will not warp nearly eliminating wide door maintenance. This high precision can be guaranteed non-warp for 50 years.
Hinge Any Way You Want
Thanks to the light weight of Sing Door blanks, you can choose whether your extra wide exterior doors use side hinges (we suggest considering the use of concealed SOSS hinges) or lightweight pivot door hardware for easy hardware installation.

Professional Pivot Door Panels
Pivot Doors are becoming the most desirable entry door, enhancing the value of high end homes.
The most cost-effective way to make a pivot door is with patented Sing panels. They are fully insulated with urethane, patented Sing core grid makes it stronger than steel pound for pound, and come with a fifty year non-warp warranty with our professional Sing panels. They are also very lightweight, which can save you hundreds in hardware costs alone, as well as save you on shipping costs, labor, and making installation safer.

These are the best true-flat, high precision pivot doors available.
These pivot door panels come standard with frame of 1.5″ wood stiles and 3″ rails, also included 4″ x 12″ wood lock blocks 30” on-center (OC) from bottom.
Standard surface = Luan plywood, upgrade to marine plywood add $100.
You can then lay up whatever skin material you wish: wood stave, steel, stainless steel, FRP or HPL on the surface of Sing pivot door panel or even cut a light opening to satisfy the design of your clients.
The professional Sing pivot door standard panel measures 4 ft x 8 ft x 2.5″ and is untrimmed.
Retail price of pivot doors made with Sing Core pivot door panels often range from $5,000.00 to $10,0000.
Custom oversize pivot doors featuring Sing Core door panels can oftentimes reach $30,000, depending on the skin and finish.

No-fail Pivot Doors
The nature of pivot doors – especially oversized large pivot doors – leads to increased maintenance costs due to warping. When you think of pivot doors warping, you first thought is to think that the door warps along the longest length from top to bottom; it is even more common side to side. Any warp will not only compromise the seal of the door but it will also prevent the door from securing and latching properly. Only Sing pivot doors can be guaranteed not to fail.
Advantages of Professional Sing Pivot Door Panels
ProfessionalSing pivot door panels are the only Eco-friendly lightweight, high strength pivot door blanks that can be guaranteed not to warp or structurally fail for 50 years.
Eco-friendly
Made in the USA professional Sing pivot door panels are manufactured using less natural resources (natural wood), recycled rigid foam and formaldehyde-free adhesives. The manufacturing process uses less energy to produce that creates little or no waste.
Lightweight Hardware
The lightweight nature of a professional Sing pivot door blank means saving thousands of dollars in labor, transportation and installation as well as the heavy duty hardware that would be necessary for a heavier door. For instance, a standard 8 ft. door would weigh-in at 720 lbs. compared to lightweight Sing Core’s 120 lbs. reducing the cost of the hardware significantly. In fact, Sing pivot doors are so light, you could use standard hinges, if you wanted to, without fail.
