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.)

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.

Sing metal wall panels lightweight stronger than steel pound for poundEspecially 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.

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.

Sliding Glass Doors

When you’re not just looking for any sliding glass doors, there’s a good chance you’re looking high and low for the best sliding glass door to suit your needs, your particular taste(s) as well as beautiful sliding French and patio doors. Normal, off the shelf glass sliding doors are not going to suit what you want in a sliding glass door. Chances are you’re looking for the best sliding glass doors, doors that are not your run of the mill sliding French or patio doors, but unique one of a kind sliding glass patio doors.

About Sliding Glass Doors

Standard sliding glass doors come in vinyl, fiberglass, rolled or extruded aluminum, and in the more expensive projects featuring natural wood to show case and frame the metal. Enter the new generation of large sliding glass doors specified and insisted upon by the most high-end door companies, architects, designers, engineers, and custom sliding glass manufacturers in the world.

The most popular sliding glass doors are inexpensive, made of vinyl, fiberglass, rolled or extruded aluminum. You are not likely to find these materials in the higher caliber jobs in the most elegant locations around the world. In these most exclusive projects, you’re more likely to find natural wood grains or hot rolled steel featured.

Now, you can have nearly any material featured in your sliding glass doors, with Sing Core inside to make the best sliding glass doors in the world. This new way of building impeccable sliding glass doors is thanks to Peter Sing’s patented and patent-pending sliding glass door frame material which enables the creation of Eco-friendly high-end sliding glass doors of any size to be built and be fully sustainable.

All backed by Sing’s unparalleled

50-Year Warp-free and Structure Guarantee

There exists no other way to build a lightweight impervious sliding glass door to come with such a guarantee without Sing Core inside.

 

 

If you really want the best sliding doors, you will need to enlist the skills and artistry of a local millwork or custom sliding door manufacturer.

Sliding Glass Doors

Sliding glass doors are the most prevalent and sought after styles of patio doors, which can and often do include several sliding glass doors in succession including overlapping sliding glass doors which are also called bypass sliding doors because one door slides over another door panel, which may or may not be a sliding patio door. Depending on the design, one or more glass doors may be stationary.

The best sliding glass doors featured in high end homes are made with wooden sliding doors that feature large glass window lite cutouts. It stands to reason, if you’re going to have a nice patio, you’re going to want to enjoy it both from the inside and the outside of your home. So, unless you’re primary concern is high security level patio doors which can be made of Kevlar and featuring Lexan clear polycarbonate, you’re going to want sliding patio doors with a view (glass installed).

Sliding Glass French Patio Doors

Those sliding patio doors with the big glass cutouts? We call these sliding glass doors, “French patio doors.” By definition a French door is a usually a wood door featuring a large window glass pane. Sliding glass French doors allow you to enjoy the beauty of the outdoors regardless of the time of year. French doors are Eco-friendly in that they maximize the availability of the natural lighting.

For The top of the line, highest end sliding glass doors, look no further.  We can make panels that will shock and awe even the competition.

 

 

 

If your French patio doors have Sing Core inside, they are lighter in weight and also insulated for climate control and also sound deadening qualities, maximizing your investment for the most Eco-friendly French patio doors.

While the sliding French patio door is intended to provide access to and from the patio area, they are also elementally and visually impressive enhancing the overall appearance of any patio access area. Sliding French patio doors are by far the most elegant patio doors, and backed with Sing Core’s 50 year warp-free and structure guarantee, are by far the most sustainable patio doors.

Wooden Sliding Glass Doors

Since wooden sliding glass doors are the preferential choice of designers, architects and owners of the most expensive homes ($20 Million & up) chances are these are going to be wooden sliding doors which are featuring large lite cut outs and are likely to be very tall, which could be 16 ft. tall wooden sliding glass doors, or taller sliding glass French patio doors. Wooden sliding doors (especially if they are large wooden sliding doors) present a number of challenges for the architects, designers and millworks or custom door manufacturers who build them. The number one problem with any long span of wood is that it will warp. It’s not a matter of if the large wooden sliding door will warp, but when it will warp.

That’s why it’s so important to have Sing Core inside your large wooden sliding doors, because a warped wooden sliding door which does not open of close is not a door at all. Although, if your door has a large window glass pane lite cutout, you will still have the view, even if the door fails, your wood French patio door can be a French patio window.

The wisest most efficient designers and architects increasingly are specifying that all their large wooden sliding doors with glass and wooden French patio doors have “Sing Core inside.”

Sliding Glass Door Design

The design of glass sliding doors, and sliding French doors in particular, can be complex and may require a true team approach to the glass sliding door design. The architect can specify the glass sliding doors, and the designer (who may also be the architect or the owner) knows what they want. The concerted efforts of the custom glass patio door builder or manufacturer, the millworks, (as well as Sing Core, if specified) and the install team, must work in tandem to solve all the pending challenges that may arise from the glass sliding door design.

Extra care must be taken in the selection of the glass sliding patio door hardware, ensuring that it is rated for exterior use, and also matched to the weight of the sliding patio glass door as it was designed. The weight of the sliding glass patio doors dictates the types and styles of sliding patio door hardware which will be necessary for improving performance and reducing maintenance over time.

For patio doors that have solid warp-free Sing Core composite core inside, these patio doors will be lighter in weight than other solid core doors, reducing the cost of what otherwise might require heavy duty sliding door hardware, which can cost many times the cost of the sliding doors themselves.

Modern Patio Doors

In this day and age, modern glass sliding doors need not adhere to the same design characteristics as their sliding patio door forerunners. In the most contemporary architectural designs custom lite openings can be designed which contrast wildly in comparison to earlier traditional designs.

 

 

It is common for Sing Core to pre-cut custom lite openings in modern sliding patio doors based on the visionary drawings of the contemporary architect, designer or owner.

By altering and creatively designing the glass openings in an otherwise sliding French door configuration, a unique glass design and install can increase the effective curb appeal and radically enhance the perceived value of a home, when the owner desires to be uniquely separated from the pack.

Plus, high end modern sliding patio doors need not be limited to being manufactured of wood. You might see these highly individualized, one-of-a-kind patio doors made of hot rolled steel, copper, or concrete, because custom patio doors with Sing Core inside could be made of any available flat building material.

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!!

Classic Hidden Hallway Door

About Hidden Doors

Hidden doors, or jib doors, are the most particularly demanding for high precision because any misconfiguration or door warp will make an otherwise invisible door stick out like a sore thumb (literally), and if it’s too far out of plumb, it may not operate at all.

Patented and patent-pending hidden door technology, you con create a flawless, high precision invisible hidden door that will operate without fail. other advantage of using Sing’s core within your hidden door include possessing an Eco-friendly door that is fully insulated for sound deadening and climate control, lightweight (one-third or less the weight of other wood based solid core doors), high strength (at 660+ PSI, stronger than steel pound for pound), impact resistant, highest precision (Sing Core sports .006-inch tolerances), and here’s the kicker,

50-Year Warp-free Guarantee

The only way in the world to build a sustainable lightweight high strength hidden door that can be guaranteed not to warp, bend, twist, or otherwise fail (including delamination) for 50 years, is to have your door build with Sing Core inside.

Sing Core is known for it’s large, showy doors. But, our lightweight door technology has many varied applications. Whenever style and durability are a factor, Sing Core panels deliver where others cannot.

A Unique Addition to Your Project

Nothing sells a finished product like the little touches. When you think that everything else has been tried, consider adding a hidden door to your project.

Hidden doors allow for additional space utilization in a design while minimizing visual clutter due to door framing and hardware. This gorgeous example, built by one of Sing Core’s clients using our patented lightweight honeycomb technology, oozes refinement and class. At a glance, the door melds in to the hallway molding and leaves the  lines unobstructed.

Our Panels are Your Canvas

An artist cannot paint without a strong canvas, likewise a builder cannot make living art without strong building materials to form their creations.

Sing Core door slabs come with a 50-year warp-free guarantee that demonstrates the underlying stability and quality of our materials. We stand by our ability to create doors that are:

  • Lightweight
  • Sound proof
  • High insulation value
  • Straight
  • Strong
  • and Dependable

When You Client Demands the Best

May companies on the market offer a variety of door cores. We acknowledge that our product is not the right solution on all situations. For doors of usual sizes and applications, or exacting production standards leave little flexibility in pricing to meet budget demands. Where our doors shine is in very large, high tolerance, or very high end applications.

When all that maters is the best possible outcome for your project, then remember Sing Core and our patented and patent pending “honeycomb” door technology cannot be beat.

Smooth, Flush Trim, and Anything You Can Imagine

Flush is just the start of the possibilities when it comes to high end custom doors. With Sing Core almost any possibility to can be realized. Almost any size can be realized using the unique strength and straightness of our honeycomb core. Too thin and too big are not in our vocabulary.

The real question is how big can you imagine? What do you and your clients seek to realize?

A Miraculous Material

Many people are surprised to see how much then can accomplish beyond the norm with Sing Core backing their work. For us strength is really not a problem. Warping can be relegated to a fear of the past.

We would be boosting to say these things if the product didn’t warrant the praise. But in this case we can, in humility, say that what we provide top end millworks, construction companies, and architects pushes the boundary of what is possible.

When you use Sing Core you are in the driver’s seat. Do you want metal skin, solid wood skin, paint, plastic, fiberglass? Almost anything can be realized with less weight and greater strength than even aluminum or other space age door technologies.

What Can We Do For You?

Although we aren’t the right fit for every project, when your design has unique needs remember that Sing Core is there to back you up.
