1. Paint Grade Door

2. Wood Grain and Wood Stave Door

3. Hardwood Plywood Door

1 Paint Grade Door

Our most popular door blanks are paint grade, and can be made to your specs including surface materials of,

  • Birch ply (most common)
  • Wood plywood
  • MDO
  • HPL
  • Other material, as specified

 

2 Wood Grain and Wood Stave Door

Besides paint grade for the surface, we also provide solid wood stave laminate on both sides of the sliding door. Wood stave is easy to work with and will last. Your Sing wood stave door will be more high precision than solid wood door (less warping, and twist and crack) due to Sing Core’s extremely high tolerance (+/- .006 inch) and, rigidity and high strength (660+ PSI) and professional grade wood grain and wood stave doors are certified and guaranteed not to warp, bend, twist, or otherwise fail for 50 years.

Sing Core provides hot-press ready door blanks to door manufacturers who add wood veneer on both sides of Sing door blanks which are made of Luan skin or marine grade plywood sandwich with patented Sing Core in the middle, solid wood around 4 edges and wood block implants where needed for hardware.

Note: Veneer has to be handled very carefully every step of the way during production (we prefer to let the millworks handle this delicate procedure) and it is easy to damage by users over the years (but wood stave can be easily sanded and repaired).

We offer a very good price for wood stave doors, the cost is not much more than wood veneer doors.

3 Hardwood Plywood Door

We could make door with hardwood plywood as an effective way to make super large doors that you can stain any color. Up to 4×8 doors have no seam, but by orienting the grain horizontally, you can achieve a nearly seamless presentation on really big doors or extraordinary size.

Available in any available wood species, most common are Sapele, Oak, and Maple ply.

Sing Hardwood ply door has excellent strength, yet is lightweight, features good insulation and better sound deadening qualities than solid wood plank doors.

Our panels make doors!

Patented Sing Core solid wood stave door blanks feature the newest technology in the door industry for composite doors yielding the only eco-friendly, lightweight, fully insulated, high-strength doors with wood blanks of any size (up to 40 ft.) that can be guaranteed true flat and to stay flat for 50 years.

Large door versus regular-size door challenge (i.e., over 4 feet wide and over 8 feet in length):

Large doors are heavy, dimensionally unstable, require more strength due to the heavy weight, and are a challenge to manufacture, ship and install.  High-end jobs require precision and true flatness to please the customer.  A homeowner’s architect, general contractor and mill worker must solve the problem of warping doors.  The solution to the challenge is to use patented professional true flat Sing panels to make your doors.

Sing Core wood stave door planks are the only solid wood doors that will not warp, bend, twist or cup following installation.  This means no more continuous service calls for maintenance of big doors that cannot possibly stay straight due to the limitations of solid wood – or any other door core – that is subject to failure.  Sing panels have a patented honeycomb/torsion box interior which gives lightweight yet unsurpassed strength (pound-per-pound stronger than steel) and stability to any door, and allows Sing Core to provide a 50-year guarantee

Interior Doors:

Sing panels make amazing designer doors in any style.  With Sing panels, fragile doors such as French doors are made lightweight yet strong, not warping or breaking hinges, which will last for many decades.

Exterior Doors:

Sing panels make sturdy exterior doors in any style.  With Sing panels, exterior doors are lightweight and strong, even when oversized.  Our professional doors are guaranteed to stay true flat and not warp or twist for 50 years

When is a door not a door? When it fails to function as a door.

The problem is that all door core materials are either not high precision, too heavy or will move when exposed to moisture, humidity or change in temperature resulting in door failure.

Heavy solid metal or steel will not warp, bend or twist, but is not high precision due to welding (sing core tolerance is + or –  .006 inch!) and is often impractical due to the overweight issues causing excess strain on both the hardware and structure, causing continued maintenance issues.  The solution is our patented lightweight yet strong Sing core technology.

Finishing a door blank:

There are two types of finish for door blanks:  paint grade and wood grain.  Paint grade includes such finishes as metal, Masonite, marine plywood, etc.  Wood grain finish includes such finish as solid wood stave and thin veneer.

Why Use Solid Wood Instead of Veneer?

solid wood composite door planks any size thickness true flatNever settle for substandard veneer doors again. Door engineers prefer to use inexpensive veneer as opposed to real solid wood facings because veneer is thought to be less likely to warp, bend or twist.  But thanks to the super-strength of patented Sing Core technology, you can use solid wood stave and wood blanks with confidence knowing that your door can be guaranteed true flat and will stay flat.

How can a solid wood-faced door stay true flat? As every woodworker knows, when using a solid wood surface, the grain will move according to moisture or temperature change causing the door to fail. When using our patented Sing Core as a substrate you can safely use solid wood because the solid torsion box/honeycomb patented material is continually keeping the wood grain straight and true.  Whereas wood stave has more wood fiber giving it more of a chance to warp than thin veneer due to the unbalance of the both side of the door moisture contents, patented Sing technology solves this problem by combining stiffing skin on both side of our patented Sing core.  This Sing panel technology eliminates the troublesome movement of the door blank — warping is no longer a concern when wood stave is combined with patented Sing core.

In addition, solid wood is easy to work with, install (no need to hot press), repair and remodel.  That’s why professionals trust Sing Core’s years of expertise in helping to design the only wood stave doors (that look just like solid wood doors) that can stay straight and true for many decades while respectfully honoring the beauty and elegance of solid wood, which far outlasts easily-damaged veneers, yet can be sanded and repaired if necessary.

Celebrate your real wood!
