Save Thousands on Your Next Order

There is a new door making technology to build door blanks for door manufacturers and millworks for any type or design of door with almost any door skin for less guaranteed by inventor Peter Sing. Less than half the labor of stile and rail door. You can save hugely on entire door schedule and get our 50-year warp-free guarantee on all your doors.

With our patented core technology and high production capacity, we are able to produce the highest quality doors at a very low price with very quick turnaround times. 

By making the same size doors, we can cut the production time in half. We add special solid edging to the doors so you can trim them yourself.

We were able to bring a customer’s order total down from

$27,500 to $13,500

for a total of

$14,000 in savings.

We did this by changing their order of 21 different door sizes down to 4 different door sizes.  The customer easily trimmed their own doors. SingCore gave the same 50 year no-warp guarantee to this customer’s order.

Here is what their order looked like before we offered them half price on their order if we could reduce the variations of door sizes:

 

Quantity Application Description
1 Pocket Door 106.5″ x 45.0″ x 2.0″; 1/8″ 
2 Pocket Door 106.5″ x 23.5″ x 2.0″; 1/8″ 
7 Pocket Door 106.5″ x 31.0″ x 2.0″; 1/8″ 
1 Pocket Door 106.5″ x 38.5″ x 2.0″; 1/8″ 
1 Hinge Door 106.5″ x 31.0″ x 2.0″; 1/8″ 
1 Hinge Door 106.5″ x 30.0″ x 2.0″; 1/8″ 
1 Pocket Door 106.5″ x 30.5″ x 2.0″; 1/8″ 
1 Pocket Door 106.5″ x 20.5″ x 2.0″; 1/8″ 
1 Pocket Door 106.5″ x 30.0″ x 2.0″; 1/8″ 
1 Hinge Door 106.5″ x 33.5″ x 2.0″; 1/8″ 
1 Hinge Door 106.5″ x 34.0″ x 2.0″; 1/8″ 
1 Pocket Door 106.5″ x 37.0″ x 2.0″; 1/8″ 
1 Pocket Door 106.5″ x 31.0″ x 2.0″; 1/8″ 
1 Hinge Door 106.5″ x 31.0″ x 2.0″; 1/8″ 
1 Pocket Door 106.5″ x 33.0″ x 2.0″; 1/8″ 
1 Hinge Door 106.5″ x 34.5″ x 2.0″; 1/8″ 
1 Pocket Door 106.5″ x 46.0″ x 2.0″; 1/8″ 
1 Hinge Door 76.0″ x 24.0″ x 2.0″; 1/8″ 
1 Hinge Door 80.0″ x 36.0″ x 2.0″; 1/8″ 
1 Hinge Door 106.5″ x 28.5″ x 2.0″; 1/8″ 
1 Hinge Door 106.5″ x 19.0″ x 2.0″; 1/8″ 

Here is what the client’s order looked like after we had negotiated removing many of the variations of door sizes:

Quantity Application Description
6 Other Door 106.0″ x 40.0″ x 2.0″; 3/8″
7 Other Door 106.0″ x 36.0″ x 2.0″; 3/8″ 
16 Non-Door 106.0″ x 27.0″ x 2.0″; 3/8″ 
1 Non-Door 106.0″ x 19.0″ x 2.0″; 3/8″ 

A typical order from a customer may consist of many different variations of door sizes. The different sizes of doors take us longer to full fill an order. If instead you place an order with all the same size doors, we can streamline our manufacturing process which saves us time and money. We in turn share those savings of time and money with you.

Let us do the most labor intensive parts and you finish the rest to build the best door in the world, especially very large door, but our standard-sized door panels are very affordably priced.

Wholesale Large Door Alternatives for the Best Door Manufacturers

The best door distributers represent the best in trusted door manufacturers across America for high confidence and superior door manufacturing ethics which translate to high quality and performance standards for upholding your credibility and professional ability to deliver only the best doors for your clientele.

What About Large Doors?

If you are like other distributors of the top selling doors from companies like VT Industries, you are getting some of the most coveted door jobs in your area of expertise. That is, for everything within the standard door size-range. Large doors are another thing altogether.

Large Doors

Large doors in your door schedule are going to be a problem. First off, your regular door supplier does not carry them, doesn’t want to build them, and doesn’t want you to sell them.

Why?

Because large doors fail. Even in the best of circumstances, with all the talent and expertise in making and installing millions of standard-sized doors, your supplier is unable to provide you with a door that will not fail after installation if its dimensions exceed 4×8.

Any door over 4×8 is going to present your valued client with problems. This is why large oversized doors are excluded from your standard warranty which covers the rest of the door schedule, because everyone knows that a large door will warp if it is over 4×8.

Where Does Your Door Supplier Go for Large Doors?

Every once and a while your door manufacturer takes on a large door job, which may include hundreds of standard-sized doors and a few large pivot doors, large sliding doors, or large hinge doors. What then? They don’t want to lose the job due to only a few large doors.  

So, what do they do?

The biggest and best door manufacturers in the world know there is only one trusted door manufacturer in the world that can make a large door that will not warp, bend, twist, cup, or otherwise fail, and that is Sing Core.

Sing Core Warp-free Large Oversized Doors

Enter Sing Core, the only large architectural door manufacturer in the United States who can build a large oversized door of any type or style that can build a large door of any material specified by your architect that can be lightweight, high strength, fully insulated, and can be guaranteed warp-free, not to fail, including a full structure warranty for fifty years.

Made in the USA

Sing Core doors are sustainable Eco-friendly doors which are proudly made by hand using safe domestic materials via our patented manufacturing methods using less energy, with very little waste, and a highly honorable respect for managing the best of nature’s materials and recycled materials for long almost service-free long life now and for generations to come.

Sing Core Door Characteristics

Besides being lightweight, warp-free, and stronger than steel pound for pound, Sing Core Eco-friendly doors bring many other high-end attributes to the end product which will be enjoyed by your clientele for years to come, adding even more value to your Sing Core door.

Some of the advantages of having a Sing Core door include being fully insulated for climate control and sound deadening qualities thanks to the high-precision (+/- .006 in. tolerance) patented and patent pending composite reinforced door core.

We Don’t Make Doors

Even though the best doors in the world are made with Sing Core inside, we don’t actually make doors at all. What we build is the best non-warping insulated door blanks in the world. We work hand-in-hand with the best door manufacturers in the world to provide your clients with the best doors in the world of any size, even huge mammoth-sized doors.

In this arrangement, as we help support the best door builders, we provide them with the non-warping substrate (what we do best) as we trust them with handling the door finishing, hardware, and installation (what they do best).

What We Can Do

We do provide your biggest and best door manufacturers with the best support system and can provide them with door blanks in various stages of readiness for them to complete in their door factories.

We are often called upon to make bulk runs of standard door blanks quickly, provide door builders with ready-to-finish door blanks prepared by attaching any available flat building materials, such as any species of natural wood grain veneer, natural wood planks, aluminum, cold rolled steel, concrete, fiberglass, FRP, galvanized steel, hot rolled steel, HPL, LVL, MDF, MDO, plywood, stainless steel, just to name a few, ready for your favorite door manufacturer or millwork to finish.

What We Can Do for You

If you have a good local custom door manufacturer or millwork that you work with locally you can order your Sing Core door blanks and have them sent directly to your favorite millwork or custom door maker for finishing, installation of hardware, and installation.

How to Get a Sing Door

You can get your Sing Door blank custom built to your architectural specifications by clicking on the orange Pricing button at the top of the page.

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.
