The Most Extreme Doors in the World by Sing Core

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

Amazing Beverly Hills Pivoter

One of the most prominent millworks on the West Coast needed the best door he could get his hands on, when he was working on the most beautiful homes in Beverly Hills. If you live in Beverly Hills, you need the best possible doors to represent your image, because unimpressive doors will damage your status. 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.

Doors are one of the most important elements of design when building the most high end residential homes. They must be strong, light weight, and warp free, according to AWI standard. 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.

Terminal C-18 knew there was only one company they could count on to get the job right. Sing Core rose to the occasion.

The panels we manufactured and provided by far exceeded their expectations.

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.

Brandner Design Incredible Accordion Pivot Sliding Door Room Dividers

With the help of Sing Core, Brandner Design’s amazing innovation and design skills made this door one of the most exceptional doors in the world. Many people thought it wasn’t possible to make accordion sliding door room divider walls. No one can shed doubt on these doors, because this video is irrefutable proof.

When their client needed a special door that could divide this room and fit into a recessed receptacle inside the wall, Brandner Design called upon Sing Core to help them with the task. No other company was better suited to the task, because our panels are stronger, straighter, more dimensionally stable, and lighter, so they’re able to accommodate more hardware and stand the test of time, even after hundreds and thousands of uses. In the door business, there is one rule that stands true, no matter what kind of door you are installing. Exceptional panels result in exceptional doors.

This beautiful mural door is an example of how an amazing designer or architect can use our panels to create the most beautiful doors imaginable. Mural doors are one of the more interesting ways to use our products. They can also add a great deal of character to an otherwise stale environment.

We can build you a substrate, ready for you to paint your own murals, or you can order doors from us in any skin.

Sing Core can make you doors in any skin

Metal Doors

Hot Rolled Steel Pivot Door

Sing Core specializes in a wide variety of exceptional quality metal skin doors. We have hot rolled steel, cold rolled steel, and aluminum skins. We also offer edge banding as a premiums option.

Unique Hot Rolled Steel Sliding Man Doors

This beautiful hot rolled steel man door can be opened and closed very. Check out these beautiful Sing Core doors we manufactured for Jet City Winery. The hot rolled steel appearance gave them the amazing darkened look. We used 20 gauge steel with edge banding, which gave the doors a very heavy look, like solid steel, but with the patented and patent pending Sing Core design, we were able to make them very light.

The best metal doors in the industry have Sing Core inside them. We start with a super strong, super light, ultra straight panel, then encase it completely in metal, resulting in a metal door that is up to 900% lighter than solid metal doors, while maintaining increased structural strength, better resistance to warping, and a much higher degree of visual appeal. No one else can do this!

Because pivot doors require exceptional strength and the need to be exceptionally straight and lightweight in order to function properly, Sing Core was the only choice. Only Sing Core can create 14 foot French doors that are lightweight, strong enough to stand on, and warp free according to AWI standards, and visually appealing enough to meet even your most rigorous needs. Quality is at the core of the Sing Core philosophy.

French Doors

14 Foot Tall French Door

Industry leading millworks, architects, and high end designers call on us to make all kinds of doors that present far too much of a challenge for other door manufacturers to construct. This was the very door many of our customers called “mission impossible.”

This 14 foot tall French door can be easily carried and transported by just a single worker, yet, pound for pound, it’s stronger than steel and warp free guaranteed for 50 years. Here at singcore, we make the impossible possible! Doing the impossible while providing you with exceptional quality products is part of our philosophy here at Sing Core.

Giant Sliding Factory Door

Sing Core High End Giant Factory Sliding Doors Increase Productivity

Sing Core Large Factory Sliding doors can be used for all kinds of industrial purposes. They are ideal for warehouses, hangars, factories, plants, manufacturing facilities, and other industrial and commercial scenarios. Using our patented and patent pending technology, we manufacture doors that are easier and less expensive to install, lighter in weight, so they allow you to use less expensive hardware than doors made by the competition.

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.

Giant Factory Door Extremely Light Weight

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.

If you need the highest strength, lightest weight, most warp free large sliding doors and large pocket doors, available in more skin options than any other door, you need Sing Core doors.

Factory Hangar Large Sliding Door 5 x 12 x 3.5 inch

Huge 20′ x 12′ x 3.5″ inch Large Factory Sliding Door for Hangars and Warehouses.

This revolutionary new door has so many skins available that you will find it suits every possible purpose. You can use this door as a large factory door, a huge sliding hangar door, massive barn doors, very big manufacturing plant doors, colossal barn doors, and other magnificent bay doors that will leave your guests and customers in awe.

The Sing Core Advantage

Another advantage to Sing Core is that you can apply any kind of skin or finishing. This photo shows high quality siding applied to the huge factory door. The siding is very easy to apply and is great in exterior weather conditions. Whether rain, snow, or hot sun, your door will be protected against the elements every single time.

Applying siding to your door will offer superior weather proofing.

Giant factory doors are a Sing Core specialty, as you can see here from the picture, which shows how large and well built our doors are.

Massive 20′ x 12′ x 3.5″ sliding factory door with siding.

This photo shows the true scale of the door. When you see a full grown man standing in front of it, the massive nature of the door is apparent.

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.

Hot Rolled Steel Doors

Large hot rolled steel panels being finished for installation in winery

Hot rolled steel panels high precision

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.)

Hot rolled steel accordian door panels quote request form example

Click for order example

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.

Dallas Innovation Center Ceiling

Sing Core is proud to play a small role in providing materials for the Blue Cross Blue Shield’s C1 Innovation lab in Dallas’ West End.

In the push for creative space that expands the limits of corporate culture and challenges the norm of industrial design, designers are searching for new materials that make their vision a reality. One beautiful example of this trend coming to reality is this space shown below.

Ceiling the Deal with Lightness and Strength

Although Sing Core has wide spread representation in the large door market in high end custom and architectural projects across the country, occasionally innovative professionals will design our product into more creative works. Above you see our light weight, strong, and warp-free patented Sing Core honeycomb technology employed as ceiling that breaks the mold of traditional design.

In this application, our technology provides a solid backing for the stark straight lines that will maintain the crisp lines indefinitely. While the geometric pattern breaks the mold of lifeless square office spaces and imbues the open design with a creative touch, our lightweight torsion box internal grid structure makes the whole system easy to work with and cheap to hang. Extravagant hardware costs are not longer an issue with our material that is 1/3 the weight of wood yet stronger than steel.

Sing Core in Rehab Buildings

For a few decades now, companies have been rehabilitating old factories and square brick structures for using as cutting edge research and development facilities. Companies find that having a place away from the main corporate office allows for improved creativity and independent thought.

Abandoned buildings provide a unique and cost effective way to attract a younger, hipper work force while maintaining a centrally located position in America’s key cites that the upcoming generation of creative people prefer.

In this environment, Sing Core is a natural choice. Our material itself is a play on natural and commonly found building products transformed in to a form that transcends conventional reality. The strength to weight ratio of our patented core is almost surreal to behold and can be employed in applications that push the boundary of what is possible.

Built for Innovation

These spaces are designed to inspire creativity. These timeless buildings, filled with an air of historical air of conformity, yet wildly out-of-the-box design, present an intriguing paradox that excites the mind to great effect.

Here at Sing Core we are constantly pushing the envelope by iteratively improving our solutions. Although our product is not flashy, our rigidity is the foundation upon which amazing possibilities are built.

Every time that we are able to contribute in our way to the creation of an amazing work such as the C1 Innovation Center, we can be proud of the countless years spent developing and refining our product.

How Can We Help You?

Sing Core is a specialist in the creation of light, strong, warp-free panels of almost any size. If you have a project that can use a panel of particular size, strength, or precision please contact us via our price quote page and let us see how we can help you today!!

Google Best Pivot Door

If you want to find the best door in the world for you next project all you need to do is to use the best tool for finding the best doors, such as:

Google search pivot door

If you’re looking for the what constitutes the best doors, then you might search for the most expensive door. You will find that the door companies which can make the most expensive doors which outperform all other doors in terms of weight, strength, and longevity are the hardest to make. That is, unless you know the secret.

Best Door Secret

Pivot doors are problematic because they only have two points of contact whereby the pivot door is operated and anchored by the pivot door hinges.

Hinge doors can be secured by multiple hinges, even a full length piano hinge which anchors one whole side of the door completely. Even so, with one side fully anchored, a large door will warp, bend, twist or cup, causing it to fail. A warped door will compromise the door seal and may not be able to allow the door latch to secure properly.

High End Pivot Doors

Pivot doors rely only on those two pivot points, one on the top of the door, and the other opposite it on the bottom of the door. It is imperative for a functioning pivot door to remain straight and true, or else you cannot operate it properly.

Only the best pivot door companies can make a high-end pivot door which can perform over time without failing due to door warp.

50-year Warp-free Guarantee

All you have to do, is to contact the top pivot door manufacturers on your search results and ask them if they offer a large pivot door with a 50-year guarantee.

If they do, these doors will all have Sing Core inside.

With Sing Core inside your pivot door, it will be lightweight (a fraction the weight of other solid core pivot doors), and high-strength (at 660+ PSI, stronger than steel pound-for-pound).

9 ft wide warp -free weatherproof pivot door

You also have the added benefit of having a pivot door which is fully insulated for climate control and sound deadening capabilities (Sing Core can be found inside the most efficient soundproof doors in the world).

You Can Laugh or Cry

When you discover the secret of the most expensive high-end doors, you might start to laugh, but before you start laughing, think about this:

You might be crying, if you make the wrong decision, and find yourself in possession of a weak door which may fail prior to when you might have expected.

This is why most large door manufacturers will exclude large doors (over 7 ft tall and 3.5 ft wide) in the door schedule from the warranty following installation. Chances are they will start to fail at the next change of season.

21 ft tall aluminum pivot door

Then you might reason (as many have) that if Sing Core can make the best doors in the world the most valuable doors in the world, then Sing Core could make anything better, and it does.

Doors and So Much More

Entire homes have been made of Sing Core, which is available in post and beam and panel formats, changing the way homes are built, including all the interior and furniture inside a Sing home.

Sing Core makes everything better and its Eco-friendly nature makes everything more sustainable over time.

A Low Cost Alternative Way to Build Very Large Sliding Doors

Although not as tough as our original one piece door designs with a 50 year guarantee, our segmented doors still come with our patented Sing Core structure inside and carry a 5 year warp-free guarantee. And, they can be sold at a much reduced price.

In the past, very large and oversize specified doors were often made as a single piece and shipped whole to the contractor for installation. This is particularly true of very large pivot doors and sliding doors. With modern door construction techniques pioneered by Sing Core large doors can be produced and shipped to the customer in several pieces. These segmented doors pass on savings to the customer while maintaining the highest quality standards for warp free door construction.

Benefits of Modern Segmented Door Construction

Building a door in sections provides numerous benefits without compromise in strength, lightness, and flatness:

See Them Come Together

More Efficient to Build

Constructing a door in smaller sections makes the door easier to handle in the factory and easier to produce in general. Having more manageable sections leads to quick and efficient construction, at a cheaper cost. Doors constructed with our modern sectional approach pass on savings to the customer.

Cheaper to Ship

Doors cores produced in sections are built to be convenient and cheap to ship compared to a door built in one piece. This may reduce shipping costs payed by the customer to receive their door purchase.

Easier to Handle

Very large doors constructed in segments conform to common sizes. When you receive the door at your site handling it in segments is usually more natural for workers used to traditional sized doors than and 4×8 materials than handling an extra large door. Leaving joining the door until it reaches the site cuts costs and saves time all the way from our factory to your building site.

Strong and Stable

Sing Core doors shipped in sections and assembled on site maintain the highest standards for strength, lightness, and straightness. At Sing core we guarantee warp-free performance of segmented doors for 5 years.

How to Assemble a Sing Core Segmented Door

Assembly of a modern sliding door constructed using Sing Core technology without any specialized tools and equipment.

1. Lay Each Panel Flat

The first step to join a Sing Core sectional door is to lay the panels on a flat surface. Any flat clean surface will work. For very large doors we like to use two straight beams laid on the ground along to hold the top and bottom of each door segment.

2. Slide a Spline in to One Side

Each spline and pocket are precisely cut to fit with strength. Our products are built with our 5 year warp-free guarantee in mind. Simply push or lightly hammer the spline in place on one side of the joint. Then your panels are ready to be fit together.

3. Joining the Panels

The final step in joining a modern sliding or pivot door is to press the sides together. This can be accomplished a variety of ways, including gentle application of a sledge hammer, a few ratchet straps, clamps, or any other means you have of providing joining force. Once joined, the door is strong and secure, built to last, and can be finished and installed as any other Sing Core door.

Cracks in Wood Stave Doors

Here, at Sing Core, we get calls all the time about problems associated with wood stave doors, especially if they are large, oversized wood stave doors. These problems, such as bending, twisting, cupping, and warping should be celebrated as wood’s natural tendency to adapt to it’s environment. Unlike other synthetic materials, wood stave is sourced from a previously live authentic tree unique unto itself, a valuable resource in the eco structure of our planet.

A tree is a living, breathing part of our environment, made of the same atomic stuff we are, a sort of shirt-tailed cousin, which survives consciously for years by continuously adapting to its environment.

Even following the harvesting of a tree’s wood, the wood’s independent slices fight for their right to continue to acclimate and survive, expressing their individuality and uniqueness.

That’s why designers, architects, and pretty much the rest of us love the look and feel of real wood. We appreciate the look of it, the design of the individual expression of the tree’s growth rings, and it makes you have a comfortable sense of being home in a virtual hug from Mother Nature.

When wood stave (natural slices of wood) is applied to a door core material, the wood will move to accommodate the environmental challenges and circumstances which it is presented with.
In the case of cracking wood stave doors, the surface crack is the nature of the wood to adjust to the tension of the door’s core. The wood is still trying to provide you with the best door ever, so it sacrifices the surface finish and moves to accommodate the needs of interior core of the door. A crack-resistant finish will result in the tension being spread over a larger surface area, developing a warped or cupped door which can be more problematic to deal with than a surface crack.

Natural wood stave doors will move, warp, bend, twist, and crack, unless they are uniquely engineered with the proper composite materials to result in a wood door that does not move.

Sing Core provides architects, custom door manufacturers, and millworks with the best structurally sound composite door core which is lightweight, insulated, dimensionally stable, and stronger than steel pound-for-pound. Properly laminated materials, including the application of the natural wood stave to the patented torsion box composite core in concert with patent pending straighteners, delivers to clients a natural wood stave door which can be guaranteed to remain warp-free, including a full structure warranty, for an unprecedented 50 years.

A cracked natural wood surface door is likely due to a moisture problem, which varies in intensity between interior wooden doors and exterior wooden doors. Any wood door needs to be properly acclimatized to avoid cracking and excessive movement, also contributing to a wood’s tendency to move would be considering the way in which the wood was sliced, cut, or sawn.

Wood stave is a much higher concept in wood-faced doors than wood veneer as wood veneer which is not susceptible to cracking or warping, it is very thin and cannot easily be repaired when slightly damaged. Wood stave is a thicker natural wood product which can easily be maintained using basic woodworking skills.

The Only 50 Year Non-warp and Structure Guarantee

When you spend $10,000 to $100,000 on a door and it warps, can you fix it? No.

It may be a beautifully and skillfully handmade door, but if it is warped, it fails to function as a door to any level of satisfaction.

These expensive doors are made with solid materials or core substrate material which is the weakest link. The core of the door determines the weight, strength, and long term performance of the door. Only doors with patented and patent-pending Sing Core technology inside can be guaranteed not to warp or fail regardless of size, exterior surface material used, or style of door for 50 years.

“We’ve switched from using LVL door core to Sing Core and no longer have to worry about warped doors.”

While LVL and wood-based door cores are fine for standard sized doors, these are not practical for large doors because they increase the weight of the door significantly making it more apt to fail, expensive to handle, maintain, and even potentially dangerous.

This is why the top door companies, millworks, and custom door manufacturers rely on Sing Core delivering the best door substrate enabling them to warranty wooden and large doors.

Would you settle for a 1-year warranty?

Most doors come with the standard 1 year warranty (large doors may only carry a 30-day warranty, or more commonly, are exempt from any warranty at all) because, as is well known and they say in the industry,

“All large size wood doors warp,”

unless they have Sing Core inside.
