Shaking Up Metal Fabrication to its Core
Sing Core’s Metal Fabrication Department is shaking up the industry!
Our new applications are changing how to fabricate metal panels: Don’t’ Get Framed! One of our clients, I-5 Designs, has us expanding our capabilities to meet the increased demand for the longest, most beautiful aluminum panels that are eco-friendly, lightweight and stronger than steel.
Traditional metal fabricated panels expend excessive energy in their creation, using aluminum framing and the result is a panel that looks acceptable but has no strength.
This is extremely advantageous when maintaining structural integrity over long spans… Check out this page on our web site: . You will see these 37 foot long beautiful ruby red aluminum panels that we are so proud of. Lightweight, eco-friendly, superior strength and gorgeous; you must see it to believe it.

Insulation: Sing Core has built-in insulation value with an R3 to R6.5 rating per inch, depending on client’s needs/specifications.
Sound deadening: Sing Core’s filler material has natural sound-deadening properties. Other sound-deadening options are available at customer request.
Light weight: When compared to other materials Sing Core weighs much less, as much as 50% less, or more, as little as 4 lbs. per sq. ft. yet eco-friendly. This advanced technology used in the aviation industry is now available for use in your home.
Strength: Sing Core based on 2″ x 2″ grids and 3/4″ thick = 660 PSI. For instance, aluminum 3/8″ grids = 30+ PSI (smaller grids should be more strength). Sing Core’s superior strength comes from its advanced torsion box design.
Solid: Sing Core is solid like a rock. While the vertical wood grain torsion box core may be compared to other hollow honeycomb cores, the Sing Core voids are not hollow as they are bonded wall-to-wall and filled with recycled foam for a strong, solid substrate.
Eco-friendly: Sing Core is manufactured using natural wood fibers, no formaldehyde, or toxic chemicals, is created using less energy than any other core material with little or no waste.
Renewable: The structure of Sing Core is 100% renewable (nature-grown) clean fiber and/or recycled material.
Oversize: Sing Core excels in area of large oversize products due to its unique properties and can be up to 50 foot length.
Dimensionally stable: Sing Core is the most dimensionally stable building material allowing us to create large, oversize products (i.e., doors, up to 50 ft.) that are true flat exceeding AWI standards and can be guaranteed to be true flat. Large oversize panels can be truly dimensionally stable without any movement due to temperature and moisture change.
Thickness available: Sing Core is readily available in many thicknesses, up to 6 inches in standard thickness, with custom thicknesses available.
Skin options: Available in many different exteriors including (but not limited to) aluminum, cement board, cold roll steel, concrete, ceramic tile, fiber glass, galvanize metal, glass, MDF, metal, plastic, plywood, solid wood, stainless steel, etc…
Easy to machine: Sing Core is easy to work with in the shop or on-site for sawing, sanding, adding solid wood implants, gluing, cutting and fastening.
Fast turnaround: In you’re in a rush, only Sing Core can be custom made within 24 hours and is proudly manufactured for you in the USA.
Even though Sing Core is less expensive than most solid material, the end result is more structurally sound, lightweight, will not compromise over time and reduces the amount of man-hours and equipment to install.
Sing Core is a honeycomb sandwich panel composite material with built in structural grids. Sing Core could have the exterior surface skin of any material including, but not limited to wood (seen in photo), metal, plastic, glass, Kevlar, even concrete and cement. The strength of our design is due to the structural grids made of naturally abundant, renewable, vertical grain veneer wood fiber. Sing Core is constructed in a fashion similar to torsion box technology most commonly found in the aeronautics and space exploration industries.
This technology is what allows our panels remain strong, lightweight, and flat without denting, cracking, and warping. See a comparison here. Inventor Peter Sing uses this torsion box technology, along with wood fiber and foam to create patented Sing honeycomb core: the incredibly strong, true flat, lightweight, renewable composite material of the future. Check out our products section to see a few different applications.
Engineering Myth-busters
- Heavy is not equivalent to strong
- Lightweight is not equivalent to weak
- Expensive material does not ensure high function
- Solid material is overused and not ecologically responsible
Most construction is a waste of materials, natural resources and has a negative impact on our planet. Solid materials are overused in an attempt to increase the strength or lifespan of the project. This excess of materials and resources is not necessary… and can be likened to killing a fly with a machine gun.
It may be hard to believe, at first, but for the first time in our history, a truly responsible structural alternative can be found in Sing Core technology. Many of our clients were skeptical when they queried us about our lightweight and strong solutions to their design challenges.
That is why Sing Core is the secret ingredient found in the homes, offices, estates and showrooms of royalty, political and religious high-end environments. Once you try the Sing Core alternative, you will never go back to traditional building materials in some cases.
Traditional honeycomb panels have come to the rescue addressing the lightweight needs of industry. Sing Core is compatible to (if not well out-performing) most honeycomb technology in terms of weight, but no other honeycomb core can compare to Sing Core in terms of strength. None.
Before today, you did not know about Sing Core’s environmentally responsible solutions to function and sustainability. Now that you do, what will you do with that knowledge?
Take the Sing Core challenge.

Sing Metal Panels
Sing Honeycomb Metal Panels are stronger and lighter than other metal panels, which can be dented by something as small as a golf ball. The torsion box core holds the Sing Metal Panel flat so that it will not warp and sag. A 16lb steel hammer will easily dent a steel or vinyl door, but not a Sing Metal Panel. Because Sing panels are efficient to produce, they are more affordable than solid steel panels.
