Warp-free, lightweight, insulated honeycomb panels

The Structural Core

No other material can outperform our patented lightweight, high-strength, Structural Core

What is SingCore’s Structural Core?

The patented foundation of all our products, such as our Custom Door cores and blanks, that possess reduced weight and increased strength solutions across many industries.

The Structural Core utilizes the strength and weight bearing qualities of vertical grain with insulated foam to form a patented torsion box that provides a lightweight, strong, structural core.

High precision lightweight high strength warp resistant insulated reinforced torsion box Sing Core high performance



Ask yourself: Are solid materials practical for your complex design and construction projects?

No. Most, if not all, materials lose their structural integrity over long spans due to their own weight creating challenges in the design. Also, natural solid materials are more apt to warp, twist, crack, expand and contract compromising your final result.

Technical Info

Detailed Description

Sing Core is made of high precision core which is +/- .007 inch (aluminum core is only +/- .015 inch). Sing Core requires special handling by skilled technicians and high-precision machinery to achieve our valued high precision. This precision is the major element required to create a high-strength honeycomb/sandwich panel. It would be counter productive if we sold patented Sing Core to people mishandling the material. It will not benefit either us or our customers. This is the main reason we invite people to use our Sing Sandwich panel which is easy to machine and glue to make your own lightweight/high-strength panels, posts and beams… the applications of Sing Panels are endless. It has been used in many industries and trades. The character of Sing Products include being super lightweight, extremly high-strength, dimensionally stable, pre-insulated and Eco-friendly.

Sing core is just like torsion box technology that has been used in the wood working trade for thousands of years, and if often compared to lightweight core, honeycomb core and other composite building materials in the industry. It is also compared to SIP (structural insulated panels) with the exception that structural insulated panels actually do not have the structural grids that are necessary for strength, making SIP less than 10% the strength of Sing Core.

Structural Core comparisons based on 2″ x 2″ Grids

Core: 99% of solid materials used in building and manufacturing today hosts wood-based core (including solid wood, plywood, particle-board, LVL and MDF). Even 100% solid material has a core that is unique to itself (solid wood, solid steel, etc.), without any lamination.

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.

Affordable: Even though Sing Core technology is used in high-end applications, we make it affordable for broad use in a large number of applications. Sing Core performance is comparable to any high-end core but could be as little cost as low-end wood product core.

Waterproof upgrade: Sing Core is available in waterproof upgrade, to accommodate your specific water resistant requirements.

Fire retardant upgrade: When used in fire retardant applications, the Sing Core fire retardant door is the lightweight, super-strong, eco-friendly alternative.

Bullet-proof upgrade: In high-security end products, most cores used in bullet-proof applications are heavy in weight, causing strain on the infrastructure, unlike Sing Core.

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.

Sing Core Block is the foundations of many products and applications including building your own hardwood on demand.

Applications of Sing Core;

Sing Core is the fundamental building block of all patented Sing Products and can be manufactured with basic woodworking tools.

All patented Sing products are start from this simple lightweight high strength core see Sing Products

You can use Sing Core as filler core to increase the void between two panels or beams to build any structure with increased density using Sing Sandwich panels and by adding solid edge and solid wood implant to create Sing Panels and Sing Post and Beams.

Sing core could solve the problem of strength, lightweight and dimensional stability of panel, post and beam structure components for many industries.

Sing products are simple to make; likewise, our pricing methods are simple and unique.

singcore sheetWhich industries use Sing core?

Sing Core has greatly impacted and modified the methods by which many products are made, affecting multiple industries and product categories.

For instance, Sing Core is providing solutions for aluminum fabricators for a stronger end product with superior strength while still being extremely lightweight, eliminating excess welding and fastening to the frame, using Sing Core’s press technology.

The result is a better eco-friendly sustainable result that looks better when the job is complete, that requires less labor, increased production output with less high-skilled labor (aluminum welders and fabricators).

Sing Core technology provides you with more strength, much lighter weight in comparison to other building materials and an aluminum panel that is true flat.

The surface of any Sing Core panel can be any substance that meets your requirements greatly enhancing the broad spectrum of industries across the board.

Can I use your Core to build curved designs?

Yes, our Core can be cut into any flat shape. It can be sanded or planed to any desired thickness.


SingCore Drop-in Process

The technology of our Structural Core is a “drop in” process. This process includes, laying a bottom skin of any flat material, then creating the solid outer edges that could also be made of any material, i.e., wood, plastic, aluminum, stainless steel, cement board, etc… implant blocks may be placed at this time at desired location if necessary.

The empty container, hollow interior, is filled with patented sing core (dropped in) that is sliced to the desired thickness. The interior surfaces are glued prior to securing the top skin then cured.

Now you have a completed panel of any length, width or thickness that can be used as a wall, modular furniture panel, cutting board, nearly anything completed and ready to go.

Sing Core block could also be used in a variety of applications, and can also be manufactured into Sing Core Panels, Posts and Beams.

Sing products are simple to make; likewise, our pricing methods are simple and unique.
