Medium-density fibreboard (MDF) is a popular material, especially because it can be precision sanded and remain very smooth which is an excellent surface area to treat, paint, or apply other materials, anything from vinyl and Masonite® to natural wood grain and metals. The upside to this material is wide open, while the downside presents a challenge.
The biggest problem with MDF is that it is not very stable or strong. The phrase we hear commonly is, “we love it, but it warps like…” (add expletive).
Patented Sing Core and our warp-free technologies enable us to provide millworks and artisans with a high end MDF surfaced material which is lightweight, high strength, and extremely dimensionally stable. Now, you, too, can have the highest grade MDF in the industry to use in your most important high precision projects without risk of failure.
This technology moves the smooth surfaced material which can easily be high precision sanded to a whole new level!
That’s why you find this revolutionary newly invented patented and patent pending warp-free technology atop the tallest building in the United States of America.
Now you can have a warp-free large MDF panel which our clients use to apply almost any laminate surface because it is so smooth, and you can even apply natural wood grain, and it can still be guaranteed not to warp, bend, twist or otherwise fail for 50 years.
Sing Core is the secret weapon used by the top millworks, large furniture designers, and the biggest and best door companies, to keep their MDF straight and true.
It is not uncommon to find Sing’s patented MDF-solution inside the most prestigious locations around the world and from beneath the sea (US Navy) to outer space (NASA) and everywhere in between.
In fact, this is the business arena where patented sing Core shines: If you have a problem keeping it straight, inventor Peter Sing’s core and his True Flat Team can provide you with a rock solid hybrid composite core covered heel to toe in MDF which can be guaranteed warp-free for 50 years.
No other Eco-friendly lightweight material can achieve such feats.
Here is a photo of the inventor standing on a 13 ft span of his core suspended between two sawhorses.
You can see even at only one inch thick there is very little deflection.
And if that weren’t enough, here’s two people standing on a 20 ft span.
Even though Sing’s patented insulation reinforced vertical grain torsion box core is often compared to honeycomb core materials, it’s plain to see that no other lightweight honeycomb core material can compare.
Whether Sing’s core is used as substrate inside panels, posts, and beams, or as warp-free door core, you will find architects, designers, and engineers empowered by having access to the most revolutionary building material which is changing the way things are made.
You will find the most famous door companies in the world entering the field of large custom door making, which they would not have even considered prior to the invention of Sing Core. Why? Because everyone knows that once a door exceeds 7 ft tall and/or three and a half feet wide, you’re looking for problems, for which now there is a solution.
That solution is Sing Core MDF, the highest grade MDF in the industry today.
We at Sing Core are so fortunate to support the arts by providing museums and galleries with the best Eco-friendly museum displays and art display materials in the world which are capable of protecting sensitive works art.
Sensitive love storage bays, large art cabinets, and display materials with Sing Core inside are carefully constructed of low volatile organic compounds (VOC) yet have the most unique design characteristics which are not limited in size or scope.
One such project included 10 ft tall cabinets which are for storing sensitive items in the San Francisco Museum of Modern Art (SFMOMA), located at 151 3rd St, San Francisco, CA 94103, supporting the arts in all aspects from storage to visual presentation.
If you visit the SFMOMA, you might enjoy visiting Jeff Koon’s $58.4 million balloon dog on display.
Due to the lightweight and high strength of Sing museum wall panels, entire display spaces can be reconfigured easily to control traffic flow for special projects or travelling displays, which are designed to be used over and over again without risk of compromising the visual impact of perfectly straight lines.
Only with the invention of patented Sing Core can museum walls be so easily assembled, disassembled, transported, stored, even reconfigured live in between showings.
And size? Size is no problem, anything from 10 ft tall warp-free love VOC cabinet doors to 40 ft tall sliding elephant doors. No project is too large for Sing Core which specializes in making the impossible possible without compromising the art, environment, or sustainability over time.
Art is precious and should be protected by the only building material which is made to last centuries and can be guaranteed to remain perfectly straight and warp-free for 50 years of faithful service without fail.
That’s why you find Sing Core in the finest historic foundations and art preservation foundations from coast to coast Sing Core is like the transcontinental railway which linked the coasts of America with its varying cultures and lifestyles by bridging the building material gap while preserving the most precious treasures from around the world.
And having access to this patented art and museum material does not have to challenge the budget of your nonprofit organization. Inventor Peter Sing has been known to partner with architects, designers, and artists to help support the preservation of the arts.
Museums and art galleries want a system that is guaranteed to be long lasting, portable, reusable, and easily assembled. Sing Core museum panels provide just that, with the added benefits of being lightweight and eco-friendly.
A two-man team can quickly and easily assemble your Sing museum exhibit in just a couple of minutes. When you are ready to take down this exhibit, the cam-lock system makes our panels easy to disassemble and store flat until you are ready to reuse them. There is no need for complicated hardware to store, catalog, sort, or maintain your Sing Core panels.
American made Sing free-standing museum walls are perfect for executing high-end exhibit displays are elegant, yet lightweight, stronger than steel, and Eco-friendlier than the competition. Our walls require little construction and can be assembled without a large crew. Additionally, our walls can be custom created to be any size according to your and are available in any material.
Our Master Quality Doors are Complimented by Our Ultra High Quality Skin and Surface Choices
Wood Veneers
Veneer allows us to create a high end finish with less weight and cost while offering a wide assortment of beautiful door surfaces. There are a number of different types of veneers that all provide excellent options that will compliment the styles of your structures. Difference species generally demand a different price. Some popular examples are Maple, White Oak, Mahogany, Cherry, Alder, and Hemlock. Veneers are sold in bundles and range in price, but generally use the most flawless wood to provide the absolute most appealing visual aspects for your doors. Standard veneer thickness is .020″, and is often used to decorate high end furniture, cabinetry, cabinetry, floors, and even plywood. You can trust Sing Core to veneer your doors, alternatively you can get substrate only and have your veneer applied locally.*
The beauty of veneer is the high quality wood grain appearance that provides you with the most natural aesthetics. Each piece is completely unique, because it is cut from the actual logs. Not only does this allow you an amazing modern appearance, but also you can achieve a more vintage, timeless, or antique look. Normally, better quality veneers are used for doors, because customers want the best looking doors they can possibly get. Door grade veneer comes in a few distinct grades.
Gorgeous Massive Mahogany Wood Veneer Door
Face Cut Options
Rotary Cut Veneer – Created by spinning the log and peeling off sheets, almost like unrolling a roll of toilet paper, rotary cut veneer is the most common type of veneer. The advantage of this type of veneer is that it results in one continuous sheet. It is a very cost effective way of producing veneer, but it results in a very unpredictable grain pattern.
Plain Sliced or Flat Cut Veneer – This is the second most common cut. In this method, thin layers are sliced one at a time along the width of the log. The slices, which are also called leaves, because the blade works its way from the top of the log to the bottom, there is a gradual transition in the grain pattern. This method of cutting parallel to the growth rings results in a V-shaped pattern that is often seen on sheets of plywood.
Amazing Sapele and Oak Stave Combo
Hard Maple
Rift Cut Veneer – Another interesting method is the rift cut process, which allows for a more straight-grained look. In this method the log is quartered, then cut perpendicular to the grain in repeating arches. The advantage to this is that you get a relatively uniform grain appearance. The disadvantage to rift sawn veneer is that it costs more, because the process is more time consuming.
Quarter Sliced Veneer – This type of veneer is also sometimes called quarter cut or quarter sawn veneer. This cut is often specified when the customer wants an exceptionally straight grain appearance. First, the log is quartered, which allows each quarter to be sliced perpendicular to the growth rings. Since leaves are cut more narrowly than plain sliced, they are much more easily lined up with other leaves, allowing for superior uniformity. Despite it’s vast advantages, this method requires a larger log diameter compared to the alternative methods. This method also achieves a sort of flaking appearance, created when the veneer knife bisects medullary rays in the tree.
Beautiful Maple Veneer Skin
Veneer Matching Options
No matter what cut of veneer is applied, without proper veneer matching, your project will not turn out as expected. Veneer matching is a true art form. The job of matching veneer is a precise job that requires a detailed approach. The appearance is partially determined by how the veneer slices are lined up on the doors.
Book Match Veneer – Every other veneer leaf is turned over, like the pages of a book. With this method, the veneer will be mirrored between each consecutive two leaf section, resulting in a repeating series of symmetrical patterns. This method is preferred by many, because of the continuity of grain. This method produces both ascending and descending prominent characteristics of the grain. Not all cuts of veneer can be used with the Book Matching method, however, but plain, quarter, or rift sliced veneers can all be used for this purpose. This book end formation tends to reflect light and accept stains differently. With this method there is also potential for wide color variation, known as “barber pole” in some species or flitches. Despite these variations, they are still considered desirable.
Random Match Veneer – This method produces a more chaotic appearance, because pieces are generally unmatched, as if the applicator has taken a series of boards and lined them up on the surface of the door. This produces a more old fashioned look, as something that was perhaps built before modern methods of veneer were invented. With this method, there is often a deliberate method to reduce grain consistency.
Continuous Match Veneer – This is when the pieces of veneer are used for both the door and the transom, allowing for a very consistent look between the door and the transom.
End Match Veneer – This is generally selected for doors with transoms. This match uses a single piece of veneer that runs from the bottom to the top of the door. Veneer can be turned turned at the joint to achieve this appearance.
Slip Match Veneer – This is one of the quickest methods of matching veneer, but requires higher quality veneer that is fairly uniform in appearance. Sheets are slipped out on the the surface one after the other, creating a wave of repeating patterns. Some frown on this method, because of the abrupt joints. This differs from book match veneer in that book match is better at hiding the joints. Uniformity of color is superior in this method, because each piece has a similar level of light refraction. It also allows for a relatively straight grain pattern.
Blueprint Veneer – is sequential veneer from a single source to cover an entire area. Complete rooms are the most impressive when they are blueprint veneered. Some jobs include matching blueprint door skins as well. Proceed with caution, making sure there is enough source material to complete the job, and there is no room for mistakes.
Natural Variations
Because wood is an organic product, each piece has its own characteristics. There is a vast array of grain patterns and formations, which can vary among trees and different flitches. Because of that, some trees may not meet standards. Other trees may considered of exceptional quality. Prices may also vary depending on the quality and appearance of the veneer. Because of variations in natural grain of each tree and differences in cuts, you can experience amazingly unique grain, pattern, and color, for each leaf of veneer, which translates into an an unlimited variations in door appearances.
In all cases, the natural wood quality will improve and compliment design elements, especially if the wood is applied in its natural state, unfettered by paints and enamels which might hinder the actual beauty of the wood.
Some species, like maple and birch can show a wide variety of color ranges. When it comes to maple and birch unlimited amounts of sapwood and heartwood, large portions may be unusable, because of unacceptable color. Sapwood lighter in color, while heartwood is darker in color. There is also the issue with light, dark, and color streaks, spots, and color variation that results from mixing sapwood with heartwood. If these sorts of variants in color and grain are not desired by you or your customers, veneer must be selected accordingly. If lighter shades of veneer are desired, you must specify sapwood maple or birch. If darker shades are required, you should select heartwood, however, this type is often limited in supply.
* = Professional veneering can be very tricky. If you are getting substrate from Sing Core and having your millwork (or someone else) apply the veneer, be certain to affirm that they have the expertise to apply the veneer appropriately. We use the highest level of professional veneer professional and techniques. We can guarantee our veneering, if you have veneering done off-site, it is their responsibility to do it correctly. A faulty veneer could jeopardize your Sing warranty.
Door Graphics and Murals
Our doors make an exceptional surface for applying murals, canvases, or printed wraps and images. This is an excellent way to make an otherwise standard looking door, beautiful and vibrant.
In recent years, graphics, scenes, or photos applied to the surfaces of doors that turn your openings into true works of art. This style of door is only limited by your imagination! Some examples are as follows:
Fine Art: Amazing portraits, scenery and landscapes, animals, objects like cars and still life images
Designs: Patterns, colors, shapes, and other abstract art
Wood Grains: Any sort of wood species, style, or colors
Plants: Beautiful flowers, leaves, barks, and other plant based imagery
Textures: Pebbled, rusted, grainy, smooth, baked earth and other textures
Other: Anything you can imagine can be printed Sing Core doors as long as you have high quality electronic images and graphic files.
We start with a smooth tempered board or Medium Density Overlay (MDO) for a best quality finish, or select a wood veneer or paint grade option for your highest quality finishes. This is only limited by your imagination!

Customer Review: Joe Ballweg
⭐️⭐️⭐️⭐️⭐️ (5/5)
*”I needed a large (10′ x 7′) pocket door fabricated for an art studio renovation that would not warp or be too heavy to maneuver. SingCore worked with the project’s budget to make their product practical. I appreciated the work Ivan did to ensure that the shop drawings were clear and met all the requirements for the installation.
Our door was shipped in 2 panels and I was given instructions regarding unpacking and joining the panels. Ivan was also helpful in offering advice on how to deal with receiving the 650 lb crate without a loading dock and with minimal help.
The process of joining the panels was involved and some preparation was required, but I asked many questions and they were all answered thoroughly and helped with the entire process. I wouldn’t hesitate to use SingCore again or recommend them to anyone needing a large stable panel.”*
— Joe Ballweg
Lightweight Yet Solid Modular Door System
First of all, Sing Core panels use our patented honeycomb core. This unique core is designed to be ultra-light while maintaining the solid feel of a traditional wood or metal door.
Even oversized doors become easy to move and install. In many cases, a single person can handle the door without special equipment. This reduces labor and makes every job easier.
In short, you get a door that feels solid without the weight that slows you down.
No Warping—Guaranteed for 50 Years
Warping ruins doors over time. It causes misalignment, poor sealing, and eventual failure. However, our Modular Door System completely solves that issue.
Each panel is guaranteed to remain warp-free for 50 years. That’s right—five decades of guaranteed performance. You can install massive pivot doors, custom sliders, or tall entry doors with full confidence.
Because the system is built to last, you won’t face costly callbacks or repairs.
Unlimited Sizes and Endless Options
Traditional doors are limited by material size and weight. In contrast, our modular design removes those limits. You can build doors as wide or tall as you need by connecting multiple panels.
Furthermore, the system works with almost any type of door: curved, pivot, sliding, or folding. This makes it ideal for unique designs and oversized architectural features.
Plus, every door is built to order. That means you choose the finish, edge banding, core options, and more. Whether you need fire-rated skins or soundproof cores, we’ve got you covered.
Easier to Ship and Faster to Install
Large doors often come with big problems during shipping. They require custom crating and oversized freight. Thankfully, the Modular Door System avoids all of that.
Instead, we ship each door in compact, lightweight panels. These smaller sections are easier to handle, store, and transport. This helps reduce freight costs and project delays.
Once on-site, the door panels connect using a concealed alignment system. The result is quick, accurate assembly that saves time—and eliminates frustration.

What About Large Doors?
If you are like other distributors of the top selling doors from companies like VT Industries, you are getting some of the most coveted door jobs in your area of expertise. That is, for everything within the standard door size-range. Large doors are another thing altogether.
Large Doors
Large doors in your door schedule are going to be a problem. First off, your regular door supplier does not carry them, doesn’t want to build them, and doesn’t want you to sell them.
Why?
Because large doors fail. Even in the best of circumstances, with all the talent and expertise in making and installing millions of standard-sized doors, your supplier is unable to provide you with a door that will not fail after installation if its dimensions exceed 4×8.
Any door over 4×8 is going to present your valued client with problems. This is why large oversized doors are excluded from your standard warranty which covers the rest of the door schedule, because everyone knows that a large door will warp if it is over 4×8.
Where Does Your Door Supplier Go for Large Doors?
Every once and a while your door manufacturer takes on a large door job, which may include hundreds of standard-sized doors and a few large pivot doors, large sliding doors, or large hinge doors. What then? They don’t want to lose the job due to only a few large doors.
So, what do they do?
The biggest and best door manufacturers in the world know there is only one trusted door manufacturer in the world that can make a large door that will not warp, bend, twist, cup, or otherwise fail, and that is Sing Core.
Sing Core Warp-free Large Oversized Doors
Enter Sing Core, the only large architectural door manufacturer in the United States who can build a large oversized door of any type or style that can build a large door of any material specified by your architect that can be lightweight, high strength, fully insulated, and can be guaranteed warp-free, not to fail, including a full structure warranty for fifty years.
Made in the USA

Sing Core Door Characteristics
Besides being lightweight, warp-free, and stronger than steel pound for pound, Sing Core Eco-friendly doors bring many other high-end attributes to the end product which will be enjoyed by your clientele for years to come, adding even more value to your Sing Core door.
Some of the advantages of having a Sing Core door include being fully insulated for climate control and sound deadening qualities thanks to the high-precision (+/- .006 in. tolerance) patented and patent pending composite reinforced door core.

Sing Core and James Abke Turn Mercedes Van into a Portable Home
James Abke is a professional of the highest caliber who is also an avid traveller. He needed the best accomodations for his extended trips in his Mercedes van. Because of his unique needs he sought out a unique company who could do something which, in most industries, is normally called “mission impossible.”
James chose Sing Core because of our proven track record of providing the most unique products that are designed to perform under the most extreme conditions. Mr. Abke needed materials to build his special luggage rack and bed in the back of his Mercedes that would allow him to eat, sleep, and work in his van.
“The panels are awesome…I have a feeling they will last a lifetime.”
-James Abke

Digital Tech
This job required a material that would be extremely strong, rigid, with virtually no flex, yet light weight. James Abke knew this was something almost no one could do. That is why he approached Sing Core, Inc.
The Force Behind Sing Core
Under the supervision of Master Inventor, Sing Core Founder, Peter Sing, we got right to the task, designing this system for maximum performance and lighter weight. Using our patented and patent pending Professional Sing Panels. Sing Core is the best product on the market for these types of applications, because our core is stronger, tested independently in UW labs to be able to withstand 660 PSI of force, up to 90% lighter in weight than solid wood, more versatile, and more visually appealing than any other product on the market.
Because Mr. Abke required only a 1” thickness on his panels, he could not use just any material. He needed the strongest, lightest weight material he could possibly get ahold of. These panels had to be stronger than steel to endure the punishment he had planned for his Mercedes van conversion. This configuration required that the system be able to hold up several hundred pounds of weight without showing any signs of stress. These panels also offer much more insulation and sound blocking capabilities than solid wood or hollow core panels, thanks to Sing Core patented and patent pending technologies.
See how small these panels fold up! They are barely noticeable once folded for storage, and they are completely out of the way, thanks to James Abke’s implementation. This design allowed him to fold down the panels so he could use them as storage or else move them to the side and use the full space in the back of the van for cargo.No oneelse can do this.
Multi Purpose Design
James Abke was driving across the country in his van when he got the idea to do the unthinkable. Because of his unique need for a system that would allow him to work, sleep, as well as, store luggage in his van he designed a system that would be able to accommodate all three.
“I worked with several Singcore agents to find a solution and came up with a panel that I was able to coat with a truck bed liner (Rhino-Liner) in order to make the panels nonskid and very durable.”
-James Abke
The icing on the cake was that Mr. Abke’s design was able even able to accommodate a bed. Because of the ultra high strength, lightweight, warp free quality of Sing Core, James Abke was enabled to design a system that could easily accommodate two people, 500 pounds with no difficulty at all, without any compromise at all to the integrity the structure. Having a bed in his van allowed him to sleep on location, anywhere.
This was the perfect application for our products.
“It was imperative to me to have light weight panels strong enough to hold two people (for camping mode) or heavy equipment (in work mode) and be thin enough to be able to be stored inside a rather compact cargo van when they were not in use.”
-James Abke
James Abke’s design was simply one of the ways we can do this. The possibilities are only limited by your imagination. We can even make drawers or other additions that can give you better storage options than you ever imagined. For this sort of application that requires such precision, high strength, light weight, and warp free character. Sing Core is the only solution for this type of situation.
We do not make SIP panels. SIP panels will bend, break, twist, and crack. They are made very cheaply with Chinese materials. Our panels are made from the absolute best materials. They are made 100% in USA, using materials sourced from the USA.
James Abke’s new system can hold huge amounts of luggage. Sing Core technology allowed him to have more than one layer of storage in the back of his van. With our technology, we can manufacture panels that are stronger, more durable, lighter in weight, more warp resistant, available in more skins, with more bells and whistles. Moreover, they come in any size, larger than any other panels on the market, they are more visually appealing, and come with many more features. Not to mention, they are the only panels on the market that come with a full 50 Year Warp Free Guarantee. They are 100% made in America, using materials sourced from the united states.
Sing Core has been making doors for nearly 15 years. During that time, we have made big and small doors, high and low, made of the best materials available on the market, built to last a lifetime, guaranteed to be warp free, according to AWI standards. Without a doubt, every door that comes through our factory is a work of art, but there are a number of doors which have exceeded all expectations to become some of the most extreme doors ever made.
The Most Extreme Doors in the World by Sing Core
Many doors have made it into the Sing Core Hall of Fame, but today let’s focus on a few of the most impressive doors.
Sliding Doors
Microsoft Huge Sliding Door
We were approached by one of the leading door and windows companies in the world, Cascade Door and Hardware to make this door that nobody deemed was even possible. With a span of 25 feet wide and a towering height of 9 feet tall, this door is, hands down, one of the largest doors in the world.
We were approached by Microsoft to accomplish a task known most often in the industry as “mission impossible.” We rose to the challenge, because we knew we could do it. This door is stronger, straighter, lighter in weight than any other door of its size in the world. Only Sing Core can do this!
We have solved all the problems with large doors, because our patented and patent pending special construction methods allow us to manufacture doors that are stronger, straighter, lighter in weight, and warp free according to AWI standards.
With our large Modular Door System you can transport multiple panels into difficult to reach areas of a work site, then join them together to make humongous doors that appear virtually seamless and function as single, complete functioning doors. You’ve never seen anything like this before, because no other door manufacturer can do this!
When you need the biggest and the best, only Sing Core will do!
Pivot Doors

Not only are Sing Core doors the strongest in their weight class, they are also up to 80% lighter than solid wood doors. Moreover, they are warp free and eco-friendly, and far more visually appealing than competing doors. They can also be made in any size with any skin.

Because of our unique patented and patent pending designs, our doors can be made with extreme precision, within tolerances of +/- .006 of an inch. No one else can do this! In the door manufacturing industry. This kind of door is often called “mission impossible” and is selected by the most prestigious architects and designers in the world.
AIA Seattle Design Center Giant Pivot Doors
AIA Seattle Design Center Giant Pivot Room Dividers
FAIA Mr. Peterson, a senior architect for Suyama Peterson Deguchi, called on Sing Core to make these huge pivot man doors for the AIA Seattle Design Center remodel. They needed doors that were extremely strong, yet light weight enough to work with their specialized door hardware. Their idea was to create a gallery that could be instantly converted into a conference area. Sing Core patented and patent pending technology made this possible by using our ultra light weight, high strength design.
Without Suyama Peterson Deguchi and Sing Core, AIA would not have been able to accomplish their tasks of converting their office space into a unique, convenient, practical, world-class conference room, gallery rife with style and elegance.

Terminal C-18 Film Screening Room, Minneapolis, Minnesota
The C-18 in Minneapolis, Minnesota Airport needed a double purpose wall, one side for their art exhibit, the other side for their quiet theater screen viewing room. The problem was that these walls needed to open and close to allow access the the foyer area.

Miller Blaker 16 Foot Tall Pivot Door
Miller Blaker came to us with one of the most challenging jobs in the entire world. They needed doors high quality enough to install on the top floor of the most prestigious building in the world. They came to Sing Core, because they knew our proven track records of building doors that are not only best in their class in terms of structural stability and strength, but also light weight enough to hang on Miller Blaker’s hardware of choice.
No one else can achieve the dimensional stability Sing Core can.
These doors had to be perfectly straight, dimensionally stable, and incredibly strong for use in such a challenging scenario. Miller Blaker required doors that were 16 feet tall, 3 feet wide, yet only 2.25 inches thick. Often these kinds of dimensions are what industry professionals call “mission impossible.” Here’s at Sing Core, we make the impossible possible.
Moreover, we built these doors with a solid oak edge that makes the entire door appear like solid wood with no seam. Only Sing Core can do this!
The best doors made with the best materials.
When Miller Blaker came to Sing Core, what we ended up with was a winning combination all around, one of the best architects in the world, paired with the best materials in the world, for doors that would end up in one of the best locations in the entire world.

Huge 20′ x 12′ x 3.5″ inch Large Factory Sliding Door for Industrial Use.
At this factory, the workers were struggling daily with their large factory door that was warping and twisting, due to environmental factors. Their door was excessively weighty and the door was extremely difficult to open and close. Door functionality was severely impaired, because of warping and twisting. It was also peeling and falling apart, due to poor construction. The managers knew they needed to fix the problem, but not just any door would do. This is why they called upon Sing Core to solve their problems.
Sing Core tackled the problem immediately with their patented solutions. First of all, because of the size of the door, they knew they would need to solve the weight problem.
With our patented and patent pending methods, solved the weight problems. This huge panel measures 12’ x 5’ x 3” thick, yet it only weighs 121 pounds so it can be easily lifted by two men, as you can see in the photo. This demonstrates there are no other panels on the market as light and large as Sing Core panels.
The Strongest of the Strong
Tested independently, in UW labs, as able to withstand force upwards of 660 PSI, Sing Core, hands down, manufactures the strongest material in its weight class. Large doors need higher strength to stave off potential warpage. That’s how we provide doors that are stronger, lighter, and more warp free, according to AWI standards.
Our panels can support the weight of a grown man with next to zero flex.
Sing Core doors also come with nearly any skin. Our most popular skins are Alder, Mahogany, Western Red Cedar, Fir, Pine, Hemlock, Balsa, Birch. Even better, we can apply hot rolled or cold rolled steel, aluminum, copper, bronze. Your doors are only limited by your imagination.

Sing Core Triple Panel Sliding Door
There are many ways to build a door. One of the most effective ways is to build multiple doors that open together in one space. There are advantages to covering your door opening with more than one panel. This allows each panel to be lighter and it offers more versatility with your hardware. Hardware does not have to be as strong, because the the weight of the full door does not rest all on one track. Also, it is much easier to install a door in sections, because very large doors tend to be heavier and much more difficult to install.
Singcore patented and patent pending technology allows us to make doors that are so large, yet so light they can be opened with just one fingure. Over the years, we have done so much research and development in the areas of strength and light weight attributes that we have been able to make panels that are much stronger, pound for pound, than competing products. When you need large industrial doors that hold up under the most rigorous conditions, Sing Core has your door.
