One of the first markets to take advantage of sandwich panels was the aerospace industry. Lightweight honeycomb cores are utilized in airplanes main bodies, the floors, and bulkhead interior panels. Beyond aerospace, advanced honeycomb, balsa, and foam cores are used significantly in the marine, wind energy, construction, and various transportation industries.
Sandwich panel cores are low in density and lightweight; but when combined with reinforcing fibers and resin, they become incredibly light, stiff, and strong structures. With mixes of lightweight cores, composite skins, and adhering methods, new sandwich structures are constantly being developed for a myriad of needs.
Today, an endless amount of cores are available from major companies such as Diab, Baltec, Rohacell, or Dow. Composite skin combinations are virtually endless as well. Thus, the first step in selecting an appropriate sandwich panel is analyzing the necessary demands. The quantity of sandwich necessary must be estimated as well to help identify the best manufacturing method. Selecting the appropriate sandwich structure, core, skins, adhesive, and manufacturing method requires a multifaceted approach to create a product that meets all engineering demands.
Why A Sandwich?
Long ago engineers realized that by adding a core to a material, the strength and stiffness could be dramatically increased with very little added weight. Cores, in comparison to the additional structural value they add, are extremely cost effective. With a sandwich, less material is required than with a solid structure.
A sandwich panel acts much like an endless I-beam; where the skins are separated at a constant distance to provide stiffness. Like an I-beam, as the skins become further apart, the structure gains more proportional stiffness. It is estimated that by increasing the sandwich thickness by two, the panel will become 12 times as stiff and six times as strong. The advantage of a sandwich is that little weight is added when increasing the thickness.
Another advantage of a sandwich panel is that the core helps distribute and absorb impact. In common cores such as balsa or foam, the skin is in constant contact with the entire core; thus during an impact, the force is distributed over a wider area. However, this is not true for all sandwich panels. For example, honeycomb, although often stiffer and stronger, has much lower impact resistance as the skin is not in full contact with the honeycomb core. In a sandwich panel, the compression strength of the core helps prevent the sandwich from wrinkling, delaminating, or buckling; all common methods of failure. As well, the core’s shear properties help the sandwich panels’ stiffness and in effect, prevent the skins from “sliding” when bending force is applied.
Sing Core is the new space age composite material that is the affordable cousin to Balsa wood and has many features that Balsa wood does not have. Using the best combination of science and nature, patented Sing Core is a Balsa wood hybrid, using a natural vertical wood torsion box design.
While torsion box has been used for centuries as lightweight structure, but Sing Core fills the open spaces with recycled foam (available in a variety of densities and material to meet your specifications), then the exterior surfaces (or skins) are bonded, completing the solid structure.
Weigh the alternatives and you can make an educated decision as to whether Sing advanced composites (the best of both worlds) will better suit your needs at less than one-third the weight of Balsa wood at less than half the price.
Balsa wood does have high compression, yet compared to other composite cores, Sing Core tests out at 660 PSI, that is stronger than steel pound for pound (even bullet proof doors don’t test that high). And Sing Core is more ecologically responsible as we use only 8% natural wood fiber (compared to balsa wood’s 100%) yet due to its unique design is much stronger when compared to other materials.
Unlike Balsa wood, Sing Panels are resistant to warp, twist and rot, and they are pre-insulated for insulation and sound-deadening.
And Sing Core is so much more affordable than balsawood, especially if you are considering incorporating it as a lightweight substrate material for a large project, like a door, a table top, conference table, etc… See more applications.
Sing Core’s built-in torsion box structure, where the grid voids are not left unfilled but are filled with EPS foam provides a solid surface for bonding exterior building materials to that will not delaminate over time. Upgrading to closed-cell foam, makes Sing Core a perfect match for marine applications, like decking materials.

True flat technology is based on expertise in building carriage doors that can be guaranteed true flat and stay flat. This composite science includes the proper proportions of Sing Core, aluminum and/or other materials based on your requirements or specification. In this way each Sing carriage door is a work of art.
Wood-based carriage doors are exposed to a variety of weather conditions, glaring sun, wind and rain and it is important to keep the surface primed and coated to make sure that it does not crack while exposed to weather.
Sing carriage doors prolong functionality of surface treatments due to being made with patented Sing Core’s torsion box structure that holds the wood surface to maintain a forever flat surface without twisting or cracking.
You may further weather-protect – even for withstanding the most severe weather conditions – by integrating other material into the surface of your Sing carriage door. Surface skins of aluminum, FRP or stainless steel will not crack like natural wood or plywood to prevent compromise of your Sing carriage door.
If you like the look of solid wood but seek high-performance and longevity, you can use Sing aluminum as your true flat carriage door’s substrate, you will be able to maintain straightness of your doors making them less likely to crack due to movement cause by expansion and contraction of the wood surface material.
See how Sing Panel’s torsion box structure prevents surface crack because of the patented Sing Core’s unique characteristics.
To keep your carriage door true flat is a challenge for solid wood or even plywood.
Sing Core and Sing Panel master true flat technology for very high-end doors requiring less that 1/16 inch deflection which is more costly.
Sing carriage doors far exceed the AWI industry standard or ¼ inch deflection to be considered flat.
Sing Panels are so versatile, you can do just about anything with them.
As a matter of fact, prepare to adjust your thinking, because thanks to Sing Wood Planks you can,
Say Goodbye to Tongue and Groove
Tongue and groove joinery is designed to keep wood planks flat when attaching because wood moves. Natural wood (or most any wood product) tends to warp, bend or twist due to environmental changes.
Not necessary when using Sing Hardwood that is created true flat and will stay flat indefinitely.
What if you needed to attach wood or tongue and groove planks to the surface of your Sing Panel?
No problem.
Just make sure that you order your Sing Panel with the solid wood (or other material) implants to meet your requirements.
You can add stiles (vertical implants) or rails (horizontal implants) to have the anchor points that you need to match your expectations.
The only caveat, is that you must leave at least 12 inches of Sing Core material on either side of the implant in order not to compromise the sustained flatness of the lightweight, high-strength panel or door.
If you have a special custom, architecturally specified, or otherwise unique requirement for your project, don’t hesitate to ask. We are experts in the unexpected, and seek to exceed your every desire. Visit our pricing page for more information and to submit your price quote request.

Our light weight aluminum and honeycomb composite is the perfect component available in nearly any aluminum thickness for use in aluminum structures.
Next up, our galvanized metal panels are equally as popular as our Sing Core aluminum that exceeds any machine aluminum strength while remaining lightweight and true flat. This is the only aluminum material that can be perfectly flat and stay flat over long spans for years.
If you are ready to take your aluminum design to the next level, Sing aluminum metal products are worth investigating in your best interest, for the benefit of your clients and a better world.
The simplest and least expensive way to join sing panels is to join in any way according to your budget and/or expertise.
Due to Sing Panels being so straight and true it is easier to join panels together because they line up perfectly unlike other building materials.
In many cases, for instance, standard 4×8 panels can be nailed, glued or channel-joined quickly and easily with satisfactory results.
Other options for fastening panels may include cam locks (see examples left and right) that can be pre-installed, making assembly and joining easy and more secure.
The Sing cam-lock panel solution is a high-demand solution for panels that are routinely assembled and disassembled, especially in moveable walls, trade show booths, and various wall cladding applications.
Thru-bolt Joining
One of the most inexpensive and secure ways to join sing panels is by utilizing a simple nut and bolt connection method, especially, if the panels will be routinely or repeatedly assembled and disassembled.
Stainless steel nuts and bolts offer the safety and security when joining sing panels.
Biscuit Joining
In many cases, Sing Panels can be pre-configured for biscuit joining at your site of factory.
Especially for large projects, this enables Sing Core panels to be sent individually, reducing shipping and handling costs, for assembly at your facility or job site.
See images below for example of biscuit assembly of Sing Panels

Beautiful, huge Sing Core joined doors. No one else can do this!
Unless specified Sing Panels do not ship edge-banded as 93% of our wholesale customers do their own edge-banding when finishing their Sing Panel.
Edge banding can take many forms from vinyl and plastic to wood and steel. Sing Panels are not intended for use as an un-banded product and may not qualify for our 50 year warranty if un-banded.

Advanced Large Panels
Sing Core specializes in extremely large panels (up to 50 feet) that are extremely true flat and use our nearly seamless assembly process.
This is the most high-end and expensive process where we perform the highly specialized meticulous work in our factory yielding the high level of perfection that many of our most discerning clients require. See: our clients.
These must be manufactured in our plant to ensure accuracy with tolerances within thousandths of an inch and are more costly to ship due to the nature of their being larger than multiple panels that can be assembled on-site.
Connectors for Connecting
Cam-Locks
One of our many features is the ability to add fasteners/locks to our panels…one example of this is the “S-Hook Lock” with a turn of the hex wrench you can fasten or unfasten your panels quickly.
The “S-Hook” fastening lock that is attached to the side of these panels to allow for easy assembly of the wall system.
With a quick turn of your wrist on the hex key your panels will be attached to each other.
Barn Door Assembly or ‘H’ Channel
If you are planning to keep your panels as a permanent structure you may choose the H-Channel attachment feature. Apply your adhesive the slide panel into the channel on each side then either veneer over the panel and channel or you may choose to putty, sand and paint your panels to cover over the H-channel.
Tongue and Groove
Tongue and groove is another fastening choice especially if you using our panels for flooring or ceiling. Make a nice almost seamless connection but give wood veneer a hardwood flooring appearance.
Biscuit Joint
This is a modified biscuit joint attachment. Similar to the H-joint the you are using a single long “beam” as the connector and gluing them together. Best use is for oversize tables (such as vacuum tables) and oversize doors as well. Because our panels are made of honeycomb rather than solid wood, they will not warp. Our honeycomb is light and strong.
Ship Lap
The ever popular ship lap as a connector alternative.
