Standard-sized Doors for Retail

You asked for it, and Sing Core delivers, and as always, goes the extra mile.

For years, Sing Core has been providing the most exclusive solutions for large high-end door manufacturing, made available to only the best custom door manufacturers and millworks. Since we started supporting the door industry rarely does a day go by when we aren’t dealing with many requests for standard-sized doors for retail installations.

Unfortunately, since our factory is only set up for one-off custom large doors, the cost of making a standard-sized door with Sing Core inside is just too cost prohibitive, except in the most high-end jobs with a large budget for architectural doors. That is, until now.

Introducing Retail-ready 3-0 x 7-0 Sing Doors

Financed by our success of building high precision Eco-friendly one-of-a-kind warp-free doors that can be guaranteed not to warp, bend, twist or otherwise fail for 50 years (no other door company in the world can do that without having Sing Core inside), we have created a new division at our factory to build standard-sized 3-0 x 7-0 doors with Sing Core inside.

These warp-free flush doors are priced to sell, so that you can now provide the best doors to your retail clientele featuring Sing Core inside at a price point that is attractive and affordable.

Priced for Retail Kick-off Event

We are kicking off this new line of retail-ready doors in the most requested size: 3-0 x 7-0 doors, available for either interior or exterior applications. You also get to choose from paint grade, veneer, or natural wood stave Sing flush doors starting at $xx.xx each, with no minimum order.

Standard lite cut outs are available (8 styles to choose from). Doors with window openings cut require a 10 piece per cut out design minimum order.

Strongest Lightest Weight Doors in the World

Kick My Door

As we kick off this event, inventor Peter Sing invites you to kick his door, which is so strong, “You will break your leg before you crash my core.”

Sing Core is renowned world-wide as the only way to build a lightweight door using high precision (+/- .006 in. tolerance) core material which is stronger than steel pound for pound (660 PSI) for building doors that can be guaranteed not to warp or fail.

Note: Kick doors with Sing Core inside at your own risk.

Ready to Ship Unfinished Doors to You

As always, Sing Core does not finish, provide hardware, or pre-hang doors. Prices are for unfinished door slabs only.

To sweeten the deal even more, we will ship to your company direct. Sing custom doors are only shipped to millworks and custom door manufacturers only, because finishing and creating the ultimate warp-free door depends highly on the craftsmen who create the finished product.

Since these are standard 3-0 x 7-0 sized doors, there is plenty of hardware and retail-ready framing material available over-the-counter, so these doors do not require the same attention to details as our custom-sized doors. The only thing is, we need to trust your skills in finishing the door.

5-year Warp-free Guarantee

Assuming the door is adequately sealed and finished, Sing Core guarantees every one of these doors, both interior and exterior doors, to remain warp-free for 5 years, including full structure warranty.

Now you can order with confidence and at special retail-ready pricing your choice of 3-0 x 7-0 doors with Sing Core inside.

How to Build a Sing Door

There is no doubt that Sing Core is responsible for the best doors in the world that can be built in any size for any functional purpose that can be guaranteed to not warp, bend, twist or otherwise fail for a full fifty years of regular use, even though Sing Core does not build doors.

Some individuals can be confused when they visit Sing Core and expect to just buy a pre-hung door that is the best door in the world, only to find that Sing Core does not actually make the door. Sing Doors are made of Sing Core, although we only supply the pre-configured base door material to achieve the results sought by the most demanding clients in the world.

Standard Size Sing Door Blanks

By popular demand SingCore introduces patented door core in economical and easy-to-use standard door width door blanks.

How does it Work?

In the real world, an architect, engineer, designer or the client conceives of the concept of their desired door. In many cases the high concept doors are problematic; some of them are large doors, which tend to fail due to their enormous size, while others may feature exotic materials that are susceptible to warp. Sing Core has the technology to create a lightweight substructure that is stronger than steel pound-for-pound and can be structurally guaranteed for 50 years under normal designed and manufactured use.

It might be helpful, for you to follow us on a journey through the making of a Sing Door.

A Day in the Life of a Sing Door

Door idea dream door concept any size any material any shape any design1 STARTS WITH THE DESIGN

The first step is the idea of the door, that beyond conceptual design is reduced to its most simplest form: The height, width, thickness of the door and the exterior material that is to be featured on the exposed surface(s) of the door.

Custom door design specifications sing core insulated torsion box door core2 SUBMIT TO SING CORE

The idea is then submitted via trade professional (possessing wholesale privileges) via our online quote request. The doors’ specifications are reviewed by our Non-warp True Flat Specialists, who can help determine what materials will be used inside the door to achieve the results expected by the end user.

If the client’s expectations include trouble-free high performance over a long life, the resulting design will be given special treatment resulting in a professional door base.

The resulting specifications are sent to Sing Core’s factory to custom assemble all the substructure components and composite materials necessary to achieve the results sought by the client.

This includes interior framing, insertion of Sing’s patented torsion box core material, solid inserts, lock blocks, fusion of other inner and surface materials plus any specified lite cutouts for installation of glass windows.

4 DOOR FINISHING

Exterior door handmade custom doors any size large door torsion box coreAfter the Sing Core factory has created the base door (door blank) it is sent to the door finisher; this could be a door manufacturer, custom millwork, industrial engineers or high end craftsperson specializing in ornate doors for elite consumers.

The door finisher applies the final finish to the door (trimming, edge routing, painting or other finish treatment), drilling, preparing the finished door for hardware and will likely install the glass (if specified, though sometimes this is done on site depending on the project).

The door finisher may (or may not) pre-hang the door (install all hardware and attach frame).

5 DOOR INSTALLATIONS

Then the door is packed up and sent to the job site, where the attending licensed contractor installs the final door.

Sing Crowd Manufacturing

In this sense, each and every Sing Door is a crowd manufactured project; it is a cooperative effort of many individuals from concept-to-installation, without whom no Sing Door would ever be made.

So, How Can I Get a Sing Door?

The process is simple; if you are a door company or qualify for a wholesale account, you deal directly with us, otherwise, you must seek out a professional anywhere within the Sing chain who will contact us and deal with us directly and they will partner with us by submitting your request to make sure you get the best door in the world custom-designed for the high performance that you demand.

The secret of the best door makers in the world is that they can use the Sing solution as their door’s base material to create a warp-free door, which is the best solution to the problem of warping doors, especially large doors which would otherwise be extremely prone to warp.

2 Lightweight, high strength, insulated and Eco friendly

The strongest lightweight door in the world is made with Sing Core inside. This revolutionary Eco-friendly building material is based on patented technology that is the best of old wood craftsmen’s technology (torsion box) and new composite technology (recycled rigid foam insulation) fused with advanced adhesives and enhanced with patent pending non-warp stiffeners. The result is an extremely lightweight panel that can span distances without deflection that has not been accomplished before in any affordable manner.

3 Easy to Install

Even the largest strongest sound deadening door can be installed in half an hour. This 500 pound Sing pivot door panel measures 10 ft. tall x 12 ft. wide x 3.5 inch thick and took less than half an hour to install in the Seattle Center for Architecture and Design.
