Our most popular door blanks are paint grade, and can be made to your specs including surface materials of,

Birch ply (most common)
Wood plywood
MDO
HPL
Other material, as specified

2 Wood Grain and Wood Stave Door

Besides paint grade for the surface, we also provide solid wood stave laminate on both sides of the sliding door. Wood stave is easy to work with and will last. Your Sing wood stave door will be more high precision than solid wood door (less warping, and twist and crack) due to Sing Core’s extremely high tolerance (+/- .006 inch) and, rigidity and high strength (660+ PSI) and professional grade wood grain and wood stave doors are certified and guaranteed not to warp, bend, twist, or otherwise fail for 50 years.

Sing Core provides hot-press ready door blanks to door manufacturers who add wood veneer on both sides of Sing door blanks which are made of Luan skin or marine grade plywood sandwich with patented Sing Core in the middle, solid wood around 4 edges and wood block implants where needed for hardware.

The Secret Disclosure of Non-warping Wood vs. Veneers Revealed

We are so excited to disclose the details of the secrets that we have discovered enabling some of our finest clients to achieve the highest performance in large wood stave products guaranteed not to warp, bend, twist or otherwise fail for 50 years.

The reason the secret has never been revealed before is due to it never being possible to create a perfectly straight large wood stave product. Wood will move (warp) or fail due to its nature; that is, until we accomplished creating non-warping products for two of our most exclusive clients.

Wood Veneer

Prior to this, wood veneer was the only option for even hoping to have a mostly flat surface, but this is still an issue when attempting to cover a long span. For instance, in an oversize large wooden table or oversized wood door, if warping is a concern, wood veneer adequately deals with the tendency of thicker wood grain surface material to move and vary over time and distance.

While wood veneer is handy, it will not survive damage very well and may not be repairable, like a solid wood stave.

We understand the advantages and nature of all types of veneers while working hand-in-hand with the veneer industry.

The Problem

Two separate clients from different locations of the United States sought us out to solve this problem:

Large doors that are often extremely heavy and often fail due to the excessive weight causing strain on the hardware and structure and warping compromising the door’s sealing capabilities.

Both clients expected a lightweight solution that was not only as warp-proof as possible but could maintain the highest degree of tolerance for flatness across the surface area. They were servicing high-end customers who understand the limitations of traditional building materials yet enthusiastically willing and able to finance the discovery of new methods to provide a no-fail solution.

The Solution Case Study

In these recent scenarios, one client requested solid mahogany wood stave while the other desired stainless steel 12 ft. x 10 ft. true flat doors. Both present their own share of challenges.

We were honored to take on the challenges – as we have always been when helping all our clients – and never more excited to know that we had overcome the challenges and achieved an entirely new level of high precision and high performance. So high, in fact, that even we had never attempted such a high standard challenge before.

The Results

We were able to produce high performance lightweight doors that were stronger than steel pound for pound, had the highest tolerance (the core approximately within .006 inch) and guaranteed not to warp, bend, twist of otherwise fail for 50 years!

That creates a new standard for the most precision high performance large doors made of hardwood or any other flat building material.

The Secret Revealed

The only way we could have achieved such high precision and high performance is due to the secret ingredient in the door’s core material: Sing Core. With patented Sing Core in the heart of these doors we were able to achieve these unprecedented standard results.

The secret of Sing Core lies in its unique reinforced vertical grain torsion box honeycomb core. There is no other Eco-friendly honeycomb panel material made in the USA that is lightweight, so strong (660 PSI) and can traverse long spans with little or no deflection. See comparison.

Secret Infused Applications

Now that we have achieved the results that were previously not possible by any known building technology, it is easy to see that a door could also be a wall. Laid flat; could be a floor, ceiling, roof, table or countertop.

How could you apply this technology to other applications?

Sustainable Longevity

Using patented Sing Core in practically anything can add life to products and projects that previously had a relatively short life expectancy were disposable and created a high demand on waste resources.

Consider using Sing Core in your next project for a better world.

Our panels make doors!

Patented Sing Core solid wood stave door blanks feature the newest technology in the door industry for composite doors yielding the only eco-friendly, lightweight, fully insulated, high-strength doors with wood blanks of any size (up to 40 ft.) that can be guaranteed true flat and to stay flat for 50 years.

Large door versus regular-size door challenge (i.e., over 4 feet wide and over 8 feet in length):

Large doors are heavy, dimensionally unstable, require more strength due to the heavy weight, and are a challenge to manufacture, ship and install. High-end jobs require precision and true flatness to please the customer. A homeowner’s architect, general contractor and mill worker must solve the problem of warping doors. The solution to the challenge is to use patented professional true flat Sing panels to make your doors.

Sing Core wood stave door planks are the only solid wood doors that will not warp, bend, twist or cup following installation. This means no more continuous service calls for maintenance of big doors that cannot possibly stay straight due to the limitations of solid wood – or any other door core – that is subject to failure. Sing panels have a patented honeycomb/torsion box interior which gives lightweight yet unsurpassed strength (pound-per-pound stronger than steel) and stability to any door, and allows Sing Core to provide a 50-year guarantee

Interior Doors:

Sing panels make amazing designer doors in any style. With Sing panels, fragile doors such as French doors are made lightweight yet strong, not warping or breaking hinges, which will last for many decades.

Exterior Doors:

Sing panels make sturdy exterior doors in any style. With Sing panels, exterior doors are lightweight and strong, even when oversized. Our professional doors are guaranteed to stay true flat and not warp or twist for 50 years

When is a door not a door? When it fails to function as a door.

The problem is that all door core materials are either not high precision, too heavy or will move when exposed to moisture, humidity or change in temperature resulting in door failure.

Heavy solid metal or steel will not warp, bend or twist, but is not high precision due to welding (sing core tolerance is + or – .006 inch!) and is often impractical due to the overweight issues causing excess strain on both the hardware and structure, causing continued maintenance issues. The solution is our patented lightweight yet strong Sing core technology.

Finishing a door blank:

There are two types of finish for door blanks: paint grade and wood grain. Paint grade includes such finishes as metal, Masonite, marine plywood, etc. Wood grain finish includes such finish as solid wood stave and thin veneer.

Why Use Solid Wood Instead of Veneer?

Never settle for substandard veneer doors again. Door engineers prefer to use inexpensive veneer as opposed to real solid wood facings because veneer is thought to be less likely to warp, bend or twist. But thanks to the super-strength of patented Sing Core technology, you can use solid wood stave and wood blanks with confidence knowing that your door can be guaranteed true flat and will stay flat.

How can a solid wood-faced door stay true flat? As every woodworker knows, when using a solid wood surface, the grain will move according to moisture or temperature change causing the door to fail. When using our patented Sing Core as a substrate you can safely use solid wood because the solid torsion box/honeycomb patented material is continually keeping the wood grain straight and true. Whereas wood stave has more wood fiber giving it more of a chance to warp than thin veneer due to the unbalance of the both side of the door moisture contents, patented Sing technology solves this problem by combining stiffing skin on both side of our patented Sing core. This Sing panel technology eliminates the troublesome movement of the door blank — warping is no longer a concern when wood stave is combined with patented Sing core.

In addition, solid wood is easy to work with, install (no need to hot press), repair and remodel. That’s why professionals trust Sing Core’s years of expertise in helping to design the only wood stave doors (that look just like solid wood doors) that can stay straight and true for many decades while respectfully honoring the beauty and elegance of solid wood, which far outlasts easily-damaged veneers, yet can be sanded and repaired if necessary.

Celebrate your real wood!

Our Eco-friendly lightweight, high strength alternative is the best solution for combating the issues associated with weight and size, especially large doors. Only our patented Sing torsion box/foam composite core combined with our years of experience provides guaranteed solutions for oversize doors.

That’s why this technology is found everywhere, from beneath the sea (US Navy) to outer space (NASA) and everywhere in-between.

Sing panels may be finished in almost any wood species, like mahogany, redwood, teak wood, cherry wood, walnut wood, cedar wood, Ipe wood, sapele wood, poplar wood, ebony wood, ash wood, oak or any other hardwood or exotic wood types available.

This same wood blank composite technology is also a common solution for high-end projects like engineered hardwood flooring, shiplap, wood furniture, wood shelves, decking, shed doors or any other application demanding high precision and exemplary performance over time.

How is wood stave/veneer added to Sing panels?

Wood stave is added directly to the metal or wood skin our patented Sing cores. Wood veneer is added to an 1/8-inch mdf attached to the metal skin. Call us for a free consultation on the best option for your project.

Wood Stave

Woodstaves (a narrow length of wood “stave” with a slightly beveled edge) can be utilized to form the exterior of Sing Core. These can be used to replace other types of solid wood building materials.

Standard wood stave exterior measures:

1/8”

Using Sing Core with wood staves is ecologically responsible doe to having the same appearance as solid wood by using fewer natural resources.

Other benefits include:

Material is stronger than (steel) solid wood
Lighter in weight than solid wood
Remains straight and flat
Rot, warp and twist resistant

Using Sing Core with wood staves reduces:

Energy consumption
Production costs
Labor costs
Shipping costs
Maintenance
Waste
