So, you may think that a bi-fold garage door is the right look for your dwelling. They have a classic look the reminisces of old times. Stables, country houses, and regal manor homes. This is exactly what Sing Core provides.
Bi-fold doors are defined by having two panels on each side of the opening, for a total of four panels. The outer panels are hinged to the wall, while the inner two are hinged to the outer panels themselves. This produces a compact operating door over wide spans. Some bifold doors will have tracks and/or wheels that support the inner panel during operation. While this may not always be necessary, doors that operate in this way are similar to accordion doors.
Residential Vertical Bifold Garage Doors
In the typical up scale residential home, wide garages are a must. But the drab old “overhead” style door is not the right fit for such a home. Enter, the vertical bifold garage door:
This door is a sleek alternative to the same old tune. Yet, it remains functional in compact, space sensitive designs. And, maintains the easy to operate functionality of the standard overhead design.
SingCore’s patented garage door panel technology is the key ingredient in such a design, where strength, lightness, perfect straight, noise and temperature insulation qualities are highly prized.
Residential Horizontal Bifold Garage Doors
The classic look, nothing beats the traditional craftsman style of horizontal folding bifold doors.
Yet, there is no reason to be stuck in old traditions when superior modern alternatives exist. SingCore’s panels are as much as 3 times lighter than tradition wooden doors, come with much superior insulation, and are guaranteed warp free for 50 years.
For that timeless look, combined with timeless durability — look no further than SingCore.
Folding Garage Door Hardware
For SingCore, hardware is no problem. Our light weight and perfectly straight construction takes the load of any hardware design that you choose. 2 hinge, 3 hinge, 4 hinge or more.
We block out internal supports exactly where you want the hardware to be. Then your crack hardware installation millwork, contractor, door installer, or other trade professional will do the rest of the work!
Bifold Garage Door Track
Bifold garage doors are the right track for the exceptional home that exceeds expectation. You may call a track for a bi-fold garage door an accordion door track. What ever track you take, make sure SingCore is on the bill.
No track is strong enough to take the beating of an exceptionally heavy door panel indefinitely. Or, prevent the warping of a wooden door. Our one of a kind building techniques avoid all these issues!
Compact Folding Garage Door
Folding garage doors can be a great asset to the human race, because they get “out of your way!”
Don’t you think that a folding garage door is in your future? Why go back when you can go forward?
Tri-Fold Garage Doors
There is no reason to stop at two, when you can have three or more of the very best panels in the industry. Our patented and patent pending door technology is uniquely suited for the stress of a tri-fold application via:
Immense strength (stronger than steel)
Profound straightness (straighter than AWI standards)
A lifetime of durability (50 years or more)
Any style, finish, or look!

Sliding metal doors were all the rage in commercial, industrial, and residential applications in the fifties and sixties. The only problem with these doors was that they were costly to maintain because these sliding metal doors were so heavy. It’s a lot of extra weight to add to a structure, especially if the structure isn’t manufactured primarily of concrete and steel.
Rollers would breakdown, bearing would fail, tracks would deteriorate, as the maintenance costs piled up over the lifespan of the door. Now, thanks to Sing Core, there is a solution for making Eco-friendly sliding metal doors which are lightweight, with Sing’s patented solid hybrid core.
The classic design and look of sliding metal doors are making a comeback in modern contemporary architectural designs and it is having huge impact, especially if the sliding metal doors are very large in size.
This new resurgence in metal sliding door design is implementing all types of metal, primarily focused upon aluminum door, stainless steel door, galvanized steel door, cold rolled steel door, and hot rolled steel door, in that order of popularity among modern architects and designers.
When contemplating the incorporation of a large metal sliding door into your design, there are many considerations to take into account. Will there be maintenance required regularly over the life of the door? In most cases, large doors will need regular maintenance to keep them functioning properly, and to repair or replace them if they either become damaged or start to warp.
Any metal door could be made of any type of available metal, though some types may be cost prohibitive, and others may be too soft to deliver consistent high performance over time, so it’s best to know your metals before you specify the material, unless, of course, price and regular maintenance are not an issue.
Aluminum and steel sliding doors definitely lead the pack over all metal sliding doors, and exterior steel doors are a hot item, and when they encounter direct sunlight, that’s when things start moving. That’s a problem which could prevent the steel sliding door from operating correctly and may cause undo stress on hardware, leading to all kinds of other problems.
When a warping metal sliding door is of concern, Sing Core is the solution, especially for modern metal doors over three-and-a-half feet wide and seven feet tall. Inventor Peter Sing can help architectural door designers to create large metal doors which can be guaranteed warp-free for fifty years.
In fact, if you have a large metal door with a 50-year warp-free guarantee, that door has Sing Core inside and it was designed, engineered, built, and finished to achieve those special results.
While Sing Core is found inside the best metal sliding doors in the world, Sing Core does not make sliding doors. Sing Core works hand-in-hand with the best millworks and metal door fabricators in the world. The result of this massive team effort to achieve such high-end sliding metal doors. No detail is overlooked.
It takes a village to build a lightweight, high strength, metal sliding door that is a one of a kind piece of work which is made to last for centuries and guaranteed to remain warp-free for at least 50 years.
You are no longer limited to a standard selection of steel doors when you can have custom metal doors manufactured to your specifications and you can forget having to rely on inexpensive hollow metal doors which will not last long, when you can have new metal doors built to last for centuries and guaranteed to remain warp-free for 50 years.
New Metal Doors
Your new custom metal doors with Sing Core inside can take on incredible features and offer benefits not found in old-style solid core metal doors.

Commercial Metal Doors
When it comes to commercial metal doors both your business and your customers will sleep better at knowing your metal doors are the top of the line.
Commercial metal doors can take on new value when considering metal doors for your next environmentally friendly construction project. Metal doors with Sing Core inside have less carbon footprint and more sustainability than traditional metal doors.
Industrial Metal Doors
It makes a difference in your manufacturing and distribution when you can depend on your metal doors to rise to whatever challenges you face over time.
Industrial sites are notorious for challenging the environment. To have industrial metal doors which can be highly effective in terms of protection from the elements, added safety and security, with the ability for even very large metal doors to remain straight without the tendency to bend, twist, cup, or otherwise fail even in the most grueling exposure to the elements and constant use.
Heavy Duty Steel Security Doors
Whether you find them in top secret government installations or in the top space and flight programs, your high precision (+/- .006 in.) and high performance (super straight for 50 years) security doors can be far superior to the metal doors you may have encountered in the past.
Imagine not having to factor-in all the added weight of your heavy-duty steel security doors, with the lightweight insulated solid composite Sing Core inside, you can have non-failing security doors that are lightweight and impact resistant and have even been used in top secret sound proof environments.
Institutional Metal Doors
Institutional metal doors with Sing Core inside are making their way into highly frequented high traffic areas within the most rigorous and prestigious institutions, ready to take on any challenges facing design, engineering, or architectural team members.
From grade schools and high schools to ivy league colleges and universities, Sing Core’s institutional metal doors can be found among the entire spectrum of institutions from correctional facilities to the Vatican, and everywhere in between.
Steel Stiffened Doors
The secret to Sing Core’s efficacy amidst the commercial, industrial, and institutional marketplaces can be found deep inside these revolutionary dimensionally stable metal doors. Inventor Peter Sing’s patented proprietary method of reinforcing metal doors in such a way so as to keep them straight and true even in the most challenging of circumstances.
See two people standing on a one-inch-thick galvanized steel panel suspended by nothing bust two saw horses with very little deflection. That is just a sampling of what is possible (and note this panel has no metal door stiffeners installed, this is just Sing Core’s base material). Combine the two and achieve heights which no one has ever been able to reach. Especially when trying to balance weight with dimensional strength and stability.
Metal doors offer many advantages over other types of doors and are commonly featured as metal security doors, in commercial, industrial, institutional, and health care fields. You want the best metal doors because all kinds of metal doors can present problems throughout the manufacturing, installation, and maintenance of a metal door’s life.
Of all the metal doors available in the marketplace today, steel doors are the most common, followed by stainless steel doors, aluminum doors, brass doors, bronze doors, cold rolled steel doors, hot rolled steel doors, Galvannealed steel doors, and galvanized steel doors.
Steel doors steal the show when it comes to metal doors. Steel front doors are by far the most popular of all steel door applications. Heavy duty steel security doors are sought out for the obvious reasons to enhance safety and security for important personnel or high-risk environments.
Commercial Steel Doors
The most prevalent commercial metal doors are custom steel doors created to serve as a metal door in a clean room, protection from extreme weather conditions, coolers and freezers. Or to fill large openings in loading docks, warehouses, parking garages, nautical and aircraft hangers.
Because metal doors are so heavy, leading to increased care and maintenance, hollow metal doors are becoming more commonplace as they are less expensive and are virtually dispensable. Rather than fixing or repairing hollow metal door, they are easy enough to simply discard and replace them with another inexpensive hollow steel door.
Government installations use metal steel doors, but its not enough to just have a door made of metal, they have greater expectations in terms of high-precision and high-performance. The most distinguishing users of metal doors are seeking out manufacturers of steel doors which can deliver better precision and performance. Architects, designers, engineers, and custom metal door manufacturers are on the lookout for the best steel doors.
Architectural Metal Doors
Sing Core puts the power to create any type of metal door made of any type of metal available. Including, but not limited to, stainless steel, aluminum, brass, bronze, cold rolled steel, hot rolled steel, Galvannealed doors, and galvanized steel doors, just to name a few.
Now your architectural metal doors are only limited by your imagination. With Sing Core inside you can design the biggest, most impressive, oversized doors (doors of any size, up to 50 ft. or more) in any style, with or without light cutouts or window openings, which may include one or more man-doors. The sky’s the limit.
Join the likes of I.M. Pei and other leading contemporary architects in creating enormous one-of-a-kind metal doors and leave your mark in the architectural world.
The Best Steel Doors
The best steel doors have characteristics which differentiate them from other metal doors which are more readily available. The best steel doors will deliver high marks on the following metal door attributes:
Sing Core makes the most lightweight steel doors which have solid composite cores throughout which weight little more than hollow steel doors, but with increased performance in all related areas across the board, which is the first item of business when considering whether your metal doors can pass the best metal door tests.
High Strength Steel Doors
Without compromising weight (see lightweight steel doors), Sing Core enables the best metal door manufacturers to provide their clientele with the best in superior strength performance. Even compare in side by side independent analysis, Sing Core is rated at more than 660 PSI, which is stronger than solid steel pound-for-pound, without all the unnecessary weight.
High Precision Steel Doors
When it comes to metal door manufacturing, Sing Core door making technology uses manufacturing methods which are may times more accurate than common welding used in metal door manufacturing. In fact, Sing Core possess the highest tolerances for metal door fabrication at +/- .006 tolerances, imbuing Sing Core with the highest possible precession for demanding, high end jobs.
Insulated Steel Doors
It’s not hard to fathom how safety and security can benefit from a highly insulated steel door. Whether in high end commercial or industrial applications, or amidst health care or residential applications, the addition of high insulation can offer many benefits, making Sing’s metal doors the most energy efficient steel doors.
Sing Core delivers insulation options throughout metal doors to provide added safety and security, which provide the end user benefits which can be demonstrated as sound-deadening and increased climate control characteristics. Sing Core is often featured inside the most effective sound proof metal doors and refrigeration metal doors capitalizing on the high insulation value of having Sing Core inside.
Low Maintenance Steel Doors
Metal doors with Sing Core inside are the most comprehensive of all doors when it comes to reducing maintenance costs over time. For instance, metal doors will mainly fail due to warp or deterioration over time. Unless you’re using disposable metal doors, you will be faced with regular maintenance issues, unless your metal doors have Sing Core inside.
Imagine having a metal door which requires very little maintenance over time. Metal doors with Sing Core inside are covered by the only known comprehensive 50-year guarantee in the industry. The guarantee covers everything from door warp to the door’s structure for fifty years. We know of no other door manufacturer which guarantees their doors to remain warp-free for 50 years, including the structure of the door over time.
Eco-friendly Steel Doors
For years, Sing Core has been the most earth-friendly way to manufacture high precision doors in a safe, sane, and earth-friendly manner, often touted as the most sustainable over time. The expected life of a metal door with Sing Core inside is 100 years, though it is guaranteed to last 50 years. No need to replace your steel doors except in the changing of design characteristics.
Sing Core uses very little energy and no toxic skilled-metal manufacturing methods with little or no waste in their patented manufacturing process of metal doors. Plus, due to their extreme light weight, these metal doors consume less energy in the delivery process, are much easier to manipulate and maneuver throughout the installation process, adding to the sustainability of Sing’s steel doors’ lifespan from creation throughout time.
That’s why you will find Sing Core used in very sensitive environments such as museums and archival installations which require very low volatile organic compounds (VOC) to protect their invaluable assets for centuries.
Guaranteed Steel Doors for 50 Years
Above all, your metal doors are backed in writing for remaining warp-free for 50 years, including the full structure over time. You can rest assured that you can have your steel doors guaranteed not to warp, bend, twist, or otherwise fail for fifty years.
The new revolution of metal sliding door starts with the latest, most significant improvement in metal sliding door design which enables millworks and door companies to build the largest metal sliding doors in the industry which can be lightweight and stronger than steel pound for pound.
Inventor, Peter Sing, empowers architects, engineers, and leading-edge designers with his patented and patent-pending technologies enabling them to create doors of enormous size of nearly any metal that can be guaranteed not to warp, bend, twist or otherwise fail for 50 years.
Materials used in these new, revolutionary metal sliding doors vary among the wide variety of metals such as aluminum, steel, silver, pewter, wrought iron, chrome, bronze, brass, brushed metal, black iron, nickel, and copper doors, just to name a few.
As you may have guessed, metal sliding doors with Sing Core inside are probably not for the average home with metal sliding doors of normal size. You’re much more likely to see these doors appearing in more high-end applications in commercial, industrial, and multi-million-dollar estates.
Sing’s patented invention imbues doors with incredible attributes which enables the best custom door manufacturers to build oversized metal sliding doors that can be fully insulated, lightweight, and very strong. Sing Core is used in large sound proof metal sliding doors, as well as being specified in climate control, fire-rated, and other highly-rated doors.
That said, nearly any metal sliding door can be lighter in weight yet have its other functions magnified many times without compromising the other characteristics or the performance of the metal sliding door.
The high precision door core (+/- .006) empowers custom door manufacturers to make a metal sliding door that is extremely accurate with the highest tolerances attainable with the ability to be guaranteed not to structurally fail and remain warp-free for 50 years.
Now, any big metal door can possess these same characteristics, whether it be distressed, such as distressed bronze metal sliding doors, distressed nickel, even architectural replacement doors and any historically restored big metal door.
Giant metal doors needn’t be big and heavy, like their predecessors, as they can utilize Sing’s complex array of composite materials which span from his basic, patented structurally reinforced torsion box core design to anti-warp technologies which enable to make large warp-free metal sliding doors reach new heights in precision, sustainability, and performance.
Made in the USA, these architectural metal doors outperform other architectural doors in side-by-side analysis, yet inventor Peter Sing says, “We don’t sell doors.” And, indeed, they do not.
Many individuals have sought out Sing Core directly for their door solutions, but Sing Core does not sell any completely finished doors. Sing Core onlyu supplies their warp-free materials to qualified millworks and custom door manufacturers who use their specific skill sets to create some of the world’s best doors out of Sing’s metal sliding door materials.
For the few people who have misrepresented themselves as being qualified to enter Sing Core’s supply chain, they have been dissatisfied with receiving an unfinished product, and who wouldn’t be, if they were expecting to receive a completely finished metal sliding door that is ready to hang.
So, if you’re on the hunt for tall metal doors or wide metal doors but you don’t want them to be heavy metal doors, Sing Core is the only known way to accomplish such a feat.

How to Get a Sing Large Metal Door
Its easy, just visit or call your local custom metal door fabricator and tell them you want “Sing Core inside” your metal door. Sing Core will work hand-n-hand with them to provide you with the best large metal door available in America today.
And, “Yes,” Sing Core was invented in America and is proudly made in the USA to reach your highest expectations.
Sing Core brings an Eco-friendly approach to working with large spans of hot rolled steel with less weight and more strength than plain steel pound for pound, revolutionizing the steel fabrication process. In fact, we are best known for our large hot rolled steel metal doors and hot rolled steel wall panels.
Our patented rolled steel panels feature custom metal fabrication uses high grade formaldehyde free adhesives instead of the more destructive welding process and your Sing Hot Rolled Steel Panel can host an exterior hot rolled sheet metal thickness of 16 gauge or more.
Sing hot rolled steel takes metal working into a whole new arena that is being embraced by steel companies making huge hot rolled steel products without having to use heavy steel framing.
These lightweight high strength hot rolled steel accordion doors (see video above) are 10 ft tall, each door panel is 3 ft wide and (brace yourself) only 3/4 inch thick… high precision and perfectly straight! (Try that with anything else… Only possible with patented Sing Core.)

One of the primary functions of Sing hot rolled steel products is in the area of commercial steel entry doors. If you are new to metal manufacturing, you will find that raw hot rolled steel has a more primitive or industrial feel to it, it has a less smooth surface than cold rolled steel and requires finishing to avoid rust or oxidation. The unique appearance of hot rolled steel panels appeals to designers, architects, museums, art galleries and often used in steel wall art.
Especially if you’re considering utilizing hot rolled steel for your large doors, Sing Core can help to mitigate the damages caused by the heavy weight of hot rolled steel doors with interior steel frames that require welding. This allows you to build hot rolled steel doors of immense size that are high precision, just like other types of Sing metal.
The Sing Core material is extremely high precision (within +/- .006 inch) which keeps your hot rolled steel door straight and flat regardless of its size. The advantages of the straighter and truer big metal doors come in handy when you multiply the door’s required integrity by two when dealing with steel double doors. Double steel doors, especially if they are large and oversized, are fraught with additional challenges.
Sing hot rolled steel can be used for upscale industrial steel doors and in commercial metal door replacements for increased performance and high precision which also supply the project with built in insulation and sound deadening qualities.
20 ft x 5 ft x 1 inch strength demonstration
Our hot roll steel solutions are changing the scope of architectural metal fabrication because the nature of hot rolled steel is predominantly restrictive due to the weight and framing required to support the raw material. Having access to a lightweight, high strength alternative, like Sing Hot Rolled Steel Panels, opens doors to unencumbered creativity.
Sing Core’s hot rolled steel doors are just some of the best doors that are among the many types of doors that have put us on the map as the best door featured in the most high end jobs across the country and the world.
You will find Sing hot rolled steel panels used not only as a standard swing door but also as hot rolled steel flooring, hot rolled steel counter tops, hot rolled steel wall panels and room dividers, hot rolled steel pivot doors and hot rolled steel sliding doors.
