A Sing Sandwich Panel can host any flat building material as its exterior surface material, making it the one of the most high performance composite materials of the future. Sing Sandwich has Sing Core® exposed edges.

  • Use Sing Sandwich as alternative to following core material (click here to see comparison Sing Core vs. other types of core)
  • Balsa wood core, plywood core, particle board core, MDF core, plastic core, aluminum honeycomb core, paper core, cardboard core, foam core

Sing Sandwich type of skin:

Sing Sandwich comes with a plywood surface material which is easy to works with in any wood shop and is becoming a common commodity in many millworks. The plywood surface material is easily bonded to other surface materials using standard wood glue and can be cold pressed, vacuum pressed, hot pressed, cut, sliced or ripped just like standard bood-based materials in your shop.

Use directly as

Shelf, tiny house, pallet, dunnage, sandwich panel walls, sandwich panel roofing,

The less expensive, lighter weight Sing Sandwich can build anything that can be built with Sing Panel.

3 Sing Panel, Post and Beam

aluminum-honeycomb-panelsThe patented torsion box composite technology is completed by adding solid edges to the Sing Sandwich to form a solid lightweight Sing Panel structure superseding precision and performance of other sandwich panels and honeycomb panels. Standard edges are inch-and-a-half solid wood but could be architecturally specified to be any known material possible. Using T Slot as your solid edge increases the versatility of the Sing Panel exponentially and is also available in Post and Beam configurations.

Honeycomb Panels


honeycomb-panel-torsion-box-coreHoneycomb Panels by Sing Core

Sing honeycomb panels are a sandwich panel composite material with built in structural grids. Our grids are made of vertical grain renewable veneer wood fiber, and foam. We construct our Singcore based on torsion box technology most commonly found in the aerospace industry. This technology allows our honey comb panels to remain strong, lightweight, and true 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 “true green” composite material of the future. Check out our products section, the applications are virtually unlimited!

The Sing honeycomb core is based on primitive torsion box designs used by high-end woodworking craftsmen, but is exponentially improved upon the basic design.

Sing honeycomb core is manufactured with LESS

  • raw materials
  • labor
  • equipment cost.

honeycomb-panels-planedOur unique manufacturing process requires LESS

  • energy for production
  • space
  • and makes less waste.

Sing honeycomb panels are

  • true flat
  • fully insulated
  • sound deadening
  • lightweight
  • extremely strong
  • last the test of time
  • and are earth friendly.

That is why the supplier of high-end custom-built oversize products to the

  • honeycomb-panels-any-dimensionPresident
  • Prime Minister
  • Kings
  • and the Pope

has sought out Sing honeycomb panels as their solution. Yet, we make this technology affordable, even to compete with cheap imports.

Sing honeycomb panels are available with solid wood edges, or without solid wood edges (photos show Sing honeycomb panels without solid wood edges).

If you are currently importing substandard plywood from off-shore, shouldn’t you think about being proud to say, “Made in the USA,” reducing your costs, delivery times and providing your clients with a superior product that is not only eco-friendly but “true green”?

Spend Less Get More With Sing Honeycomb Panel

Every Sing honeycomb panel is packed solid with insulation wall-to-wall within the patented torsion box-like structure, making it solid as a rock and stronger than steel pound-for-pound.


Sing Honeycomb Panel Core Structure
The secret of the Sing honeycomb panel is in the Sing core. Our Sing honeycomb core utilizes torsion box honeycomb board core technology to ensure strength, enabling our product to be extremely lightweight and high strength.

True Flat
Sing honeycomb panels utilize torsion box strength honeycomb board technology in order to ensure flatness.


Vertical Grain Wood Fiber
The heart and soul of Sing honeycomb panel is in our patented Sing Core invention. The core utilizes renewable vertical grain wood fiber and foam, to create our stronger than steel, lightweight, composite material.


High Strength
Sing honeycomb panels are stronger than steel, solid wood, plastic, metal, glass, brick, and concrete in terms of pound per pound comparison.


Sing honeycomb panels are high strength, flat, and lightweight. A 4’ x 8’ x 1 ½” panel with 1/8 “ Luan plywood skins, and solid wood edging weighs in at about 55 lbs. A standard sheet of plywood weighs in at about 96 lbs.


Lightweight High Strength Honeycomb Panels of Any Size

Any dimension for unparalleled strength and performance. Even when used as post and beam.

Rot resistant honeycomb panels

Even without coating, Sing honeycomb panels outlast plywood, solid wood, MDF, and particle board. Plywood and engineered wood rot crack because of the weak glue layers. Sing honeycomb panels last because underneath the skins lie Sing Core, which keeps the panels flat through torsion box technology, and therefore doesn’t allow the panel to crack.

Sing Core are the honeycomb panel manufacturers that can guarantee a lifetime of performance for a lifetime of uninhibited service.

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 patened 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 bwtween 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  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 Sing Core blocks to build curved designs?

Sing core can be cut into any flat shape. Sing Core is versitile and can be sanded or planed to any desired thickness.


Sing Core Drop-in Processsingcore drop in 1

The technology of Sing 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.

Peter Sing- inventor and president of Sing Core- spent forty years of his life to create this new sandwich honeycomb panel technology and with hard work and great perseverance, he has succeeded in his goal. His next step for his company, is to spread the word out to everyone. Peter Sing believes that people are crazy for settling with heavy, non-versatile, and expensive plywood/particle board when they can use Sing Core’s lightweight, affordable, and reliable honeycomb panels.

Imagine being able to use a lightweight, strong, wooden honeycomb panel that allows you to create anything from basic furniture or large sliding door to an entire house that you live in. But Sing Core is cheaper and friendlier to the environment. Sounds too good to be true, but it’s not, because Sing Core Honeycomb Panels give you that advantage. This new and innovative style of honeycomb panel is so much more than lightweight, strong, and durable; it is long lasting, reliable, simple, and affordable.

Why use thick plywood- that can be difficult to construct with- when you can use the versatile Sing Core honeycomb panels. Through Sing Core, you will have the components to be able to build thousands of Sing Core products, with that eco friendly touch.


Pictured to the right is a 1 ton truck on a piece of 1/4″ inch thick Hardy Plank wrapped around our Honeycomb core. it does not crack under the pressure of a 1 ton truck. This is the future economical, concrete home structure. The picture is proof. Can you drive a 1 ton truck over a conventional frame home wall without it cracking??



Sing Core Honeycomb Panel description:

  • Strength– Is more than 10 times the strength of aluminum honeycomb core. A one inch by one inch grids aluminum core only has 60 psi; Sing Core 2”x 2” grids have reached more than 660 psi, the smallest core possesses more psi strength, but failed the test against Sing Core. Sing Core grid’s sizes range from 2 in x 1.5 inch to 5 in x 5 inch.
  • Sing Core with Application– Starts from 4 lbs. per cubic ft. and the larger the core grids, the lighter it weighs.
  • Dimensionally Stable– Doors made of Sing Core are guarantee to be true flat. Since we assure the flatness of Sing Core doors, our customers haven’t requested any refunds for their purchase. The most popular door that we manufacture are oversized doors (larger than 7 ft. x 3 ft.). We can do any custom size; the largest door/movable wall we sold was shipped to Bangkok, Thailand and was, 32 ft wide x 16 ft tall (four of them to divide a large conference room to several small conference rooms or a banquet hall).
  • Eco Friendly– Sing Core honeycomb panels are made of renewable veneer. The Sing Core panels take less energy to build a strong composite core, lightweight (which take less energy to transport), has longest life span, and it’s environmentally friendly (compare to other type of core such as paper honeycomb, aluminum honeycomb core, and plastic core).
  • Sing Panels- Come complete with solid wood edging, pvc edge, aluminum edge, or open edges.
  • Skin Choice- Several different skins: such as aluminum, FRP, cement, plastic, and wood. Sing Core products are suitable for indoors/outdoors, plus, our panels are waterproof because of the many different varieties of skin and close cell foam to keep the panels completely watertight. There are two types of wood based panels; paint grade and wood grain.
  • Thickness- Sing Core honeycomb panels come in any thickness from 1/2 in. to more than 8 in. size of Sing panels;The largest door/movable wall we build are 32 ft wide x 16 ft in length (It weighs less than 800 lbs App. 1.5 lb per sq ft),With our patented Sing core biscuit layin under each join  which keep the Sing large oversize panel true dimensionally stable without any movement due the the temperature and moisture change (We offer a 10 year structural guarantee) paint grade.

Multiple Sing Panels can be joined together by a variety of methods to create entire structures or large multi-panel projects on-site using a variety of fastening options.

Sing Core Panels are typically Paint Grade- Produced ready to finish by consumers and businesses. Panels are paint grade, not paint ready, which means that the customer may have to putty, sand and prime before painting.

Custom Choices for Wood Grain- There are paint grades, wood grains skin for Sing panel finish treatment, and there are two type of wood grain Sing panel available. Option 1 is veneer/staves and option 2 is strips/planks. Sing plywood skinned panels are used to build doors, floors, walls, table tops, and roofs; It’s the least expensive and the natural plywood has a thin layer of wood veneer on the surface (the advantages are very affordable, can be stained/ shows beautiful wood, difficult to sand, repair, and has tiny join if it is over 4 ft x 8 ft size).

Two Types of Wood Grain- Sing plank- The 1st type is plywood type of wood skin which uses 1/8 inch wood stave of any kind of wood species, pressed on the top of Sing core panel(advantage: wood stave Sing panel can be sand,repair,like solid wood due to the thicker wood surface).click here to see picture. The 2nd type, is Sing wood grain panel glued to the  natural wood stave slice solid wood to 1/8 inch thick then glue on top of Sing torsion box long panel. Sing true wood planks normally range from 7 in. to 10 in., wide x 8 ft. or 10 ft. in length x 1 1/2 inch thick which look more true flat than real solid wood (click here to see pictures), than glued edges. Sing wood planks can form a large oversize door, table, or wood plank. Sing Core panels could be made at any size and thickness. Sing wood planks are light weight, true flat, fully insulated, and sound deadening than solid wood. Sing Core panels look and function better than solid wood which will warp and shrink. (it would be impossible to join solid wood planks to build doors as large as 10 ft wide x 12 ft or larger). See picture of Sing Core Flooring. Natural planks provide beautiful wood and Sing wood panel invention will make it even more beautiful and function better.
