We do not sell finished doors, but provide door planks to door industries and mill workers with patented Sing Core panels to build the most true flat, insulated premium doors in the world guaranteed. Warping is a challenge for high-end door makers. However, premium Sing Doors are highly insulated doors that will NOT warp, bend or twist.
Premium Sing Doors made of patented Sing Core materials and special skin are the only Eco-friendly, lightweight, high-strength, insulated doors that are true flat and will stay true flat for 50 years guaranteed (with our free consultation and an additional cost) regardless of application or size.
The secret is our patented Sing Panelscombined with appropriate skin (even wood), length, thickness and knowledge of years of experience in handling thousands of over-sized, challenging doors (for example see our Warehouse door). See our coast-to-coast clients list.
Patented Sing Core panels are about 15% the weight of particleboard, pound per pound stronger than steel and cost less, but more dimensionally stable than any wood core, a great advantage in your factor-in shipping costs. This technology has endless applications. Click here to see how: Door News Archive
Note: Only certified-premium (with free consultation) true flat Sing Doors qualify for our 50-year guarantee. For other true flat doors, we may be able to make them more flat than the industry standard by adding more thickness and strong skin with a proper Sing core in order to build a true straight but less costly door plank.
Any type, style or appearanceof any door with any shape, size or number of window-light openings, CNC cut-outs to offset the high labor cost of traditional style and rail doors. One more reason that Sing doors are making record sales.
Our most recent developments include our highest performance large door solutions yet. Take for instance our most precision lightest weight and highest strength large wood pivot door that is not only true flat but guaranteed to stay flat without warping, bending or twisting for 50 years!

Sing Punch-Proof Doors
SINGCORE-The new generation of door making it impossible to punch through and destroy.
As low as $50 a door for a door that will last a lifetime.
Today, the most common doors found in private residences contain a paper core. These doors are flimsy and are easily punctured, even when slightly impacted. Owners of these doors find themselves spending time and money on repairs, replacements, and installations that would not have been an issue had they purchased a door from Singcore. Singcore doors do not cost much more than paper-core doors, yet they have been tested to be at least 49 times stronger.
Door Security
How secure are your doors? With our patented core, you can rest assured that our torsion box technology will stand up to harsh treatment and all weather conditions. Our doors have been thoroughly tested and have been proven to withstand the impact of a sledgehammer. There is no comparison between the stability, structure, and strength of Sing Core doors versus paper-core doors.
This is a Sing Overhead Garage Door Panel compared next to a typical steel overhead garage door panel. Same size and thickness but as you can see the steel panel buckles with only a few pounds put on it while the Sing Panel holds almost all of Inventor Peter Sings weight without any problem.
Stronger than Steel,
Lighter than Wood
Doors do not have to be made out of steel to be rigid and strong. Sing Core doors are stronger and lighter, than steel and vinyl doors. Standard steel overhead garage doors are made of steel so thin that a golf ball can dent it. This is not the case with Sing Core doors. We offer higher quality doors at prices competitive with steel doors with quality superior to wooden doors.
Sing Core doors are more stable, provide better insulation, and are far lighter than solid wood doors. The torsion-box core holds the Sing Core door flat, ensuring that that the panel will not warp and sag like ordinary wood.
Patented Sing Door Methods
Sing Core doors are versatile and customizable. Every order is custom designed with the client’s project in mind. Each door is constructed using methods that specifically cater to our customers’ individual needs. We construct our doors using the following methods: pole barn grade, paint grade, wood grain grade, andplank grade.
How We Build Our Doors (The Best Method – Sing Torsion Box Panel Method)
The easiest way to build the best doors.
Step 1 – Apply Glue to the Skin
Step 2 – Build Solid Wood Frame
Step 3 – Install the patented Sing honeycomb torsion box core & press on the skins.
Step 4 (optional) – Cut hole for window and prepare window trim.
Step 5 (optional) – Install glass and finish the door to desired look and function.
Step 6 – Install the door onto jam.
Method 2 – How We Build Our Doors (The Second Best Method – Stile Rail)
On the left are patented Sing honeycomb stile and rail. On the right is veneer (walnut) ready for gluing onto the patented Sing honeycomb stile and rail.
Apply glue to our patented Sing honeycomb stile and rail.
Press veneer to patented Sing honeycomb stile and rail. Most honeycomb panels cannot handle the high pressure and temperatures of the hot press, Sing honeycomb can.
Stile and Rail after the veneer has been pressed on.
