Sing Core is the number one source in America for Eco-friendly lightweight high-strength aluminium sliding doors made in the USA. Architects, millworks, artisans, industrial engineers, and door companies are raving about Sing Core being the only way to build lightweight large aluminium sliding doors that can be guaranteed not to fail for 50 years.
No other aluminium sliding door made anywhere in the world can compare to all the revolutionary characteristics of aluminium sliding doors with patented Sing Core inside, such as,
Lightweight Aluminium Sliding Doors
Aluminium sliding doors with Sing Core inside weight a fraction the weight of other solid core aluminium sliding doors, thanks to the combination of new and old technologies fused into a lightweight solid substrate that is lighter in weight without compromising strength.
High Strength Aluminium Sliding Doors
Sing Core imbues any aluminium sliding door with the strength that is far superior compared to any other lightweight structural building material. So strong, in fact, it was independently rated at 660 PSI; stronger than steel pound for pound. Not to mention,
Insulated Aluminium Sliding Doors
As if all the lightweight and high strength attributes were not enough, Sing Core comes along and ramps up the features to include packing the aluminium sliding door with rigid insulation material which adds both increased climate control and sound deadening qualities which are all the rage, adding even more value to any sliding door with Sing Core inside. But wait, there’s more…
Warp-free Aluminium Sliding Doors
One thing all architects and engineers agree on when it comes to large aluminium sliding doors, is that they tend to fail by moving (bend, twist, cup) due to warp, especially in an exterior sliding door application. Aluminum will bend according to sunlight and/or climate difference on either side of the sliding door, rendering it useless. A warped sliding door is a problem, that can now be fixed and backed by Sing Core’s
50 Year Warp and Structure Guarantee
Sing Core is the only aluminium sliding door that can be guaranteed not to warp, bend, twist or otherwise fail, including full structure warranty, for 50 years, making Eco-friendly Sing aluminium sliding doors the most long-lasting and sustainable sliding doors in the world, proudly invented and manufactured in the USA.

Keeping in mind that any steel sliding door with Sing Core inside will be a lightweight steel door, which are also available in any other materials, including, say, a copper sliding door, or any other lightweight metal sliding door.
See Sing Core for all your sliding metal doors, if you’re interested in the next generation of lightweight metal sliding door.
What’s the latest news in sliding doors in the door industry? Internal sliding doors with Sing Core inside are being specified by architects more and more in their sustainable housing and commercial designs. See our new C Series line of Affordable Barn Door and Sliding Closet Doors.
Long the solution for exterior sliding doors due to their Eco-friendly, long lasting solution for warp-free lightweight yet high strength as sliding doors which are exposed to weather conditions, sometimes, even the most severe weather conditions. For years, architects and designers have sought out the characteristics that only Sing Core can provide for high precision and superior performance over a long life of the architectural exterior sliding door.
As architects became more and more accustomed to specifying Sing Core in their door specs, they started to develop a taste for specifying large internal sliding doors also. Large internal sliding doors, especially if they are wooden sliding doors, are going to fail due to warp if they exceed a height of 7 ft. tall sliding doors.
Then as the trend to specify Sing Core in internal sliding doors continued to grow, something began to shift. In high end homes, commercial and industrial applications, architects were also specifying sing Core for standard sized internal sliding doors. As this trend continues, the question is,
Why Spec Sing Internal Sliding Doors?
That’s the question, right? And you might be surprised about the answer, because Sign Core is the obvious solution to exterior or large oversized sliding door which have the tendency to warp, bend, twist, or fail structurally not long after installation. It’s the only way to build a lightweight wood exterior sliding door exposed to the elements which can be guaranteed not to suffer from door warping for 50 years. So, that explains exterior sliding doors and large sliding doors, but regular-sized internal sliding doors?
Well, it turns out that inherit deep within the patented Sing Core composite sliding door core, which is a solid composite material made of vertical grain wood torsion box core which is fully insulated with rigid insulation inside. The result? A lightweight, super strong internal sliding door that is insulated and possesses the additional attributes of being able to control climate (an advantage of using Sign Core inside external sliding doors) and also imbuing the door with sound deadening qualities, a useful and highly sought after feature in upscale projects.
Sliding Door Hardware
Due to the lighter weight of the internal sliding doors, there is a great savings in terms of the sliding door hardware. Both in the cost of the hardware due to handling the lighter weight sliding door, but additionally in the installation of the hardware and maintenance over time, as the lightweight sliding internal doors cause less stress and strain on the hardware and structure with regular use over time.
Pocket Door
One of the best uses of internal sliding doors with Sing Core inside is in the pocket door application. Pocket doors are the most important in terms of remaining straight and true because while a sliding door is far more forgiving, warped sliding pocket doors are become destructive to both the pocket door and the pocket which houses it, any further warping renders the sliding pocket door useless.
Pocket Door Hardware
Just as in the savings in sliding door hardware, pocket door hardware associated with sliding pocket doors featuring Sing Core inside is far less expensive to purchase at the outset and reduces the cost of pocket door installation, as well as requiring less long-term maintenance. Not that cost is always of the most importance in the most high end applications, but it means you can use those funds elsewhere in your project without affecting the overall budget.
Internal Sliding Door of Any Type
Whether architecturally specified at the beginning of the project, or as the most predominant use of internal sliding doors with Sing Core inside in replacement doors, your Sing architectural sliding doors are custom built to architectural specifications. They can be made of any available flat building material in any style of door. That is to say, all custom professional grade Sing sliding internal doors are one-of-a-kind warp-free pieces of art that can be guaranteed to remain warp-free (including full structure warranty) for 50 years.
50 Year Guaranteed Internal Sliding Doors

Metal doors which are made using the patented and patent-pending Sing Core technologies are celebrated around the world as being the best metal doors in the world.
Why Do You Need Sing Core Inside Your Metal Door?
Metal Door Problem
Its well-known metal doors are neither Eco-friendly nor sustainable solution and they have the potential to fail more often than not for a variety of reasons. Metal doors warp when hit by the sun’s rays, or exposed to heat or cold, and if there are varying environments on either side of the metal door, such as an exposed exterior metal door, you know trouble is not far away. Also metal doors are extremely heavy which causes hardware or the structure to fail due to added stress and strain due to the heavy weight. Plus, the bigger the metal door, the more likely it will fail and require expensive maintenance calls to repair or replace.
Metal Door Solution
THAT is why you need Sing Core inside your door. Using Sing Core is the only way to build an Eco-friendly sustainable lightweight solid core metal door that is stronger than steel and comes with a full warp-free and structure guarantee for 50 years.

Serving the Top Metal Sliding Door Manufacturers in the World
Sing Core provides professional Sing Core metal sliding door core to the top four metal sliding door manufacturers in the world (with billions of dollars in annual sliding metal doors) enabling them to create a high precision, high performance custom metal sliding door that can be Eco-friendly, made in the USA, lightweight and high strength sliding metal door, that can be guaranteed not to fail for 50 years.
Sing sliding doors make the best sliding wood doors in the United States and around the world. No other Eco-friendly lightweight sliding door core is stronger. Weighing in at a fraction of the weight of solid wood door core, patented Sing Core is stronger than steel pound for pound (660 PSI). This is the only way to make large oversized sliding wood doors that can be guaranteed not to warp, bend twist or otherwise fail for 50 years.
Each professional sing sliding wood door can be guaranteed to remain warp-free for 50 years, including a full structure warranty. This is why Sing Core sliding wood doors are making such a huge impact on the door industry across the USA and abroad.
Any type or style of sliding wood doors can be made with Sing Core inside, such as exterior sliding doors, sliding barn doors, interior sliding doors, sliding patio doors, sliding room dividers, French sliding doors, stile and rail sliding doors, just to name a few.
Patented Eco-friendly Sing Core sliding wood doors are proudly made in the USA, using sustainable manufacturing methods using less energy, with responsible use of recycled and renewable resources, including natural wood fiber, producing little or no waste or loss of energy, leaving a negligible carbon footprint.
There is just no other way to make 20 ft. tall sliding wood doors that will not warp. Wood is a very difficult resource to use for anything over 7 ft. tall because of its tendency to move, especially in exterior sliding wood doors. For instance a sliding wood door that faces the elements on one side and the structure’s interior on the other is going to warp. That’s why no door company guarantees warp resistance of a wood door for more than one year, that is, unless it has patented Sing Core inside.
So, how can you get sliding wood doors with Sing Core inside? It’s easy, just go to your favorite architect, sliding door manufacturer, mill work, or sliding door company, and tell them what size door you want and be sure to ask for, “Sing Core inside.” We cannot sell or ship Sing Core doors directly to consumers or do it yourselfers, as we are the manufacturer supplying Sing Core sliding door core only to door manufacturers and builders of custom doors.
Large oversized wooden doors are the greatest hurdle facing architects and designers, because though there is little more impressive than a huge wooden door to catch your attention, so the bigger the better, but then there’s the issue with warping, which is a constant struggle for the owner to secure regular maintenance of such a beautiful door, likely at least seasonally.
Thanks to having Sing Core inside, you will never have to worry about warping doors again. While they are built to last for centuries, each professionally guaranteed Sing wooden sliding door can be non-warping and include a full structure warranty for 50 years. No other Eco-friendly, lightweight, high strength can have such a guarantee in the world.
And what if you’re looking to build a large sliding door out of a material other than a natural wood grain? No problem, your sliding doors could be made out of any available flat building material, such as aluminium sliding doors, cement, concrete, fiberglass (FRP), glass, HPL, Kevlar, LVL, MDF, steel (cold rolled steel, steel diamond plate, galvanized steel, hot rolled steel, etc.) as well as the only unbreakable mirror sliding doors, just to name a few.
One of the best uses in emerging technologies attributed to the Sing Core solution for sliding doors is that of sliding French doors. In the scope of sliding French doors, the door is framed with a significant amount of solid material detail, such as is found in wooden sliding doors or aluminium sliding doors, but the main visual feature of the doors is a large pane of glass, similar to that of a glass sliding door. The result is a French sliding door which features the best of both worlds, an elegant frame with a large glass opening (lite opening).
Large Sliding French Doors in Office Building
Sliding French doors are more common in exterior uses, such as sliding patio doors.
Sliding Patio Doors
Sliding French doors make fabulous sliding patio doors which can feature many patio sliding doors in a line to offer greater visibility between the indoors and outdoors. Plate glass sliding door can be extremely heavy and may risk injury of little fingers which may be in the wrong place at the wrong time. The lighter weight Sing sliding door solution helps mitigate the risk of injury from sliding patio doors, while offering increased safety and security as wells as a degree of insulation which would not be possible for a simple sliding glass door left to itself.
Sliding Internal Doors
While sliding doors are used to separate the indoors from the outdoors, increasingly they are finding their way inside the home in a variety of sliding internal door applications. Sliding internal doors appear in a variety of sliding door designs. The most modern sliding doors are stylistically fashioned after the sliding barn doors of yesteryear.
Sliding Barn Doors
Sliding barn doors are set apart from other types of sliding doors due to the type of sliding door hardware which is a major component of the design of the sliding barn doors. Sliding barn door hardware traditionally is on top of the door from which the sliding barn door hangs. Exposed wheels roll back an forth on an exposed track, which gives the impression of an old style rolling barn door, like you might have seen out in the country or in old movies, or TV shows depicting barns which featured this type of sliding barn door.
Though the architectural sliding door design features may vary depending on the presentation, as the sliding barn door surface material may have a rustic appearance, or a highly polished modern sliding barn door appearance, which may feature wood, or other more contemporary sliding barn door materials.
Sliding Wall
One of the most popular uses of an interior sliding door is the concept of the sliding wall, which is not unlike the sliding patio door design, but usually features a solid door facing which could be either wood or some type of metal, such as aluminum sliding doors or steel sliding doors, used as a method to provide insulated separation between adjoining rooms, or dividing a large space into two or more separate rooms, while still retaining the large space, when needed. In this case, sliding doors room dividers can be sliding internal doors, feature barn door sliders, or a combination of folding sliding doors, depending on the architectural specifications of the sliding partition wall units.
Wooden Sliding Doors
Wooden sliding doors are the most problematic doors due to Mother Nature’s wood grain’s tendency to move according to the environmental conditions within the proximity of the faces of the wooden sliding door. In this sense, the door can seem very alive as it tends to bend or cup. This is one of the primary benefits of featuring Sing Core inside any type of wooden sliding door because it’s the only known method of creating a strong, lightweight, solid core wooden sliding door that can be guaranteed not tio warp, bend, twist or otherwise fail for 50 years.
Warp-free Sliding French Doors
Sliding French Door Specs
The only known method for manufacturers of sliding French doors to create a warp-free sliding French door is to start with patented Sing Core’s insulation reinforced torsion box composite solid core material with patent pending warp-free technology to prevent the large oversize sliding door from failing for the service life of the wooden sliding doors, which would otherwise fail. Sing Core provides the sustainable Eco-friendly lightweight, high strength, torsion box composite technology to sliding door manufactures that can be guaranteed warp-free for 50 years.
A sliding door that moves can jeopardize the sliding door lock, making it difficult, if not impossible, to secure. Let’s face it, a door that cannot be secured, is not much of a door at all. While warp-free is a huge advantage of sliding doors with Sing Core inside, another benefit is huge savings in sliding door hardware and maintenance over time.

Sliding Door Hardware
The weight of the sliding door determines the size and nature of the sliding door hardware to be used to accommodate the sliding door’s operation. Whether the doors operation is as an automatic sliding door, or manual sliding door operation, the sliding door mechanism and hardware must be suited to the weight of the door. For heavy sliding doors, the sliding door hardware could cost many times the cost of the sliding door itself, which includes the sliding door handles. Fortunately for sliding doors that have Sing Core inside, they weigh a fraction of the weight of other solid core doors, which accounts for being able to utilize lighter weight sliding door hardware to match the sliding door, which also reduces stress and strain on both the structure and the hardware over time saving time and money over the life of the sliding door.
Sliding Door Repair
Of all the materials with which a sliding door company could build a sliding door, Sing Core is the most sustainable Eco-friendly material made in the USA, and can easily be repaired on site. For instance, in commercial sliding door operations, heavy equipment could damage the door, such as being punctured by forklift forks. If the doors are made of other traditional core material, the entire door might have to be replaced. But if you have Sing Core inside, the door can easily be repaired without compromising the high performance, precision, strength, security or insulation qualities of your sliding door with Sing Core inside.
If you’re looking for the best in large sliding door design, you’ve come to the right place. Sing Core specializes in creating the ultimate sliding door experience. That’s why you see Sing large sliding doors everywhere on planet earth and beyond, from beneath the sea (US Navy) to outer space (NASA) and everywhere in between.
Sliding Doors
The deal with sliding doors is that you want your sliding doors to remain straight and true throughout their service life. Architects, designers and end users face the issues associated with the problems associated with sliding doors, such as,
Problems with Sliding Doors
The first problem with sliding doors is that they tend to move (warp, bend, twist or cup) compromising the doors’ performance. Especially in the case of sliding doors because they hang parallel to a wall (like sliding barn doors), another door (such as double sliding doors) or within a wall (like sliding pocket doors). If the door does not stay straight, it can wreck either the sliding doors or the surfaces they slide against, or both.
Heavy Sliding Doors
One way to deal with the problem of warping sliding doors is to build them using extremely heavy and warp resistant materials, such as steel, which introduces whole new set of problems, which will increase maintenance costs over the life of the door. Even though the heavy sliding door may not warp, it will require expensive heavy duty hardware (which can cost many times the price of the door itself) which can easily be compromised due to regular use, as well as the added stress of using a heavy door, will add stress and strain to the frame and structure, also requiring additional maintenance over time. Some architects and designers might consider using a lighter weight metal, such as,
Aluminum Sliding Doors
Of course, aluminum sliding doors make more sense; though contemplating the use of solid aluminum sliding doors will still introduce the problem of heavy weight. One way to manage the weight of the door is to use a honeycomb material, such as aluminum honeycomb, paper honeycomb or some other type of honeycomb material inside the otherwise hollow core sliding door. The only problem with that is that as you introduce a lightweight substrate, the door begins to warp again, especially if they are exterior sliding doors.
Wooden Sliding Doors
Ah, the elegance and beauty of natural wood. We love it and exotic wood grains can instantly garner the awe and attention of anyone spying a large sliding door made of wood. This is why many large sliding doors are wooden sliding doors. As magnificent and appealing as they are, wood is the worst culprit of all, because it can barely sit still for as long as you can. Due to wood’s natural characteristics, it is most prone to warp, bending, twisting and cupping, because even separated from the tree, it still fights for survival and the grain will either expand or contract due to the elements it is presented with. Exterior doors are the most problematic because one side faces the interior space, while the other side faces the elements outside, a perfect recipe for door warp.
Large Sliding Doors
The bane of perplexed custom sliding door manufacturers is the additional challenges with doors which are taller than 7 ft. tall and wider than 3.5 ft. Very few, if any, custom door manufacturers or millworks will even consider guaranteeing a door over seven feet tall. Why? Because they know it is going to fail, and they will be called upon to deal with it. In most cases, the job as a whole will have a warranty on the work done, with the exception of the large sliding doors which are normally noted as exceptions to any warranty that might cover the rest of the job. That is, unless you know the answer to the problems associate with large sliding doors.
Sliding Door Design Problems Solved
Architects and engineers are constantly perplexed with the problems associated with sliding doors, fortunately an Eco-friendly composite solution made in the USA, helps to solve the problems associated with faulty sliding door design. Patented Sing Core, along with their true flat door team, can help to create sliding doors that will remain straight and true far beyond the service life of any other sliding doors.

Standard Sing Core Cold Rolled Steel Sliding Door Blanks are manufactured with patented Sing Core material as the base interior substrate of the door. The Sing Core substrate material is created using a vertical grain natural wood torsion box design while the traditionally empty voids are filled wall to wall with recycled foam. The foam material is available in various forms depending on your specification. The default is recycled EPS foam. Natural wood lock blocks can be positioned at locations as necessary for locking mechanism placement and/or as sliding hardware anchor points. The core material is framed by 1.25-inch wood stiles and rails for finishing strength and attaching hardware. The torsion box is completed by adhering 20 gauge cold rolled steel as exterior material (skin) according to your specifications. The man door opening is cut out to architectural specifications.

Large sliding doors are a challenge for any door manufacturer, especially if they are more than 7 ft. tall because they will warp, compromising the performance of the sliding doors and causing strain on hardware and structure due to heavy weight. That’s where Sing Core comes in.
Our non-warp experts – and the clients that we serve – know that Professional Sing Panels are the only materials that can create a lightweight, insulated, high precision large door that can be guaranteed for 50 years for warp and structure.
Sing Core is growing in popularity across all industries as the large door solution, especially if doors are prone to warp (which most big doors are) but we also help architects, door manufacturers and high-end millworks create the best Doors of Any Size, type or style and is increasingly being sought out for endless products.
How to Build a Large Non-warp Sliding Door
The first step is to contact us with the specs for the doors that you want. The specific size(s), the exterior surface material desired and the functionality of the door, including exposure to weather conditions.
Next up, your specifications are reviewed and conferred with the trade professional via FREE Consultation.
After your free consultation, the True Flat Team will help design to design the metrics matrix of your door’s composition to result in a door that can meet or exceed your expectations and be guaranteed not to warp, bend, twist or otherwise fail (including full structural integrity) for 50 years.
At the factory, door substrate specialists bond all the materials (patented Sing Core, interior hard point blocking, Professional Sing Panels, surface materials and edging) to the design specifications.
Professional Sing Panels are extremely strong and resistant to deflection, like these non-warping door blanks that are lightweight and stronger than steel pound-for-pound.
Then skins are applied and following curing, the door blanks are shipped to door finishers who complete the door manufacturing process.
Now, your door is ready to go to the job site for installation.
The final result is an Eco-friendly lightweight, insulated, high precision large door that will not fail for 50 years, guaranteed.
These large lightweight panels with extraordinary strength can also be true flat and used for sliding doors, barn doors, carriage doors, moveable walls; if laid flat, can become table top, stage floor or mezzanine floor.
Check out the new doors for one of the world’s largest distributors of mint oil! We were really happy to build two sets of large oversize doors for an essential oil warehouse recently. One pair of panels became the double door set opens to the sides (left), while the other set of three rolls off to the same side (right).
It was important for the customer that the doors fit their doorway shape and be easy to roll. These sliding doors have a patented torsion box foam core that will keep them lightweight and smooth rolling. The series of three rolling doors link together and slide so easily that one person can push it open with just one finger.
The customer was satisfied not to need special slider tracks for our panels. Even though the doors are enormous, they don’t have the weight problems of solid core doors.
When Peter hand delivered the panels, everyone was smiling because they knew they had made the right decision in purchasing non-warping Professional Sing Panels.
