Introducing the new staple of lumber and hardwood mills, factories and yards:

Sing 2 x 12 Wood Plank

The Sing 2 x 12 is the most versatile eco-friendly hardwood lumber replacement in the world. Now available in Bamboo-style format.

eco-friendly-sing-core-beams-strength-lightweightNo other wood 2 x 12 can match the performance features of Sing’s 2×12, like:

  • Lightweight
  • Straight and true
  • Twist, cup and warp resistant
  • Super strong (stronger than steel lb for lb)
  • Eco-friendly

Sing 2x12s are Flat, Straight and True

Each Sing 2×12 is extremely flat, with no twisting or cracking, unlike solid wood. Sing 2x12s can be used just like any other conventional hardwood, or softwood to build furniture, used as building material for boats, signs, planks, trade show displays, etc…

Sing 2x12s require no tongue-and-groove. Why? Because Sing 2x12s are straight and true, will not warp or twist over time. Therefore, assembling multiple lengths of Sing 2x12s is easy, painless and requires no tongue-and-groove to act as anti-warp control. Sing 2x12s can be joined edge-to-edge with standard carpenter glue, leaving a perfect seam every time, that will last the test of time.

Sing 2x12s are Dimensionally Stable

Lumber is unstable. You know what it’s like to try to find a straight piece of lumber… Then, once you use that piece of standard lumber, who’s to say how straight it will be in a year, or ten years? Tounge-and-groove was invented in an attempt to try to deal with the instability of commercially available lumber.

The unparalleled versatility makes Sing Core’s 2×12 the most amazing product to hit the woodworking industry since… the saw.

  • substrate

Take Your 2×12 to the Next Level

The Sing 2×12 is not any type of soft wood or hardwood that you’ve ever known before; it is a basic material to build almost everything we use in our daily life.

1 Sing 2 x 12 x 8 foot panel

Why have we developed the Sing 2 x 12 x 8 foot Sing Plank?

  1. The Sing 2×12 is a superior match having the greatest amount of flexibility in diverse applications.
  2. Sing 2x12s can be produced in train load quantities. It has all the features of Sing Panels but at a lower cost. Sing 2 x 12 planks could use as substrate. Sing 2x12s can be edge-glued or end-glued to join and create any length or width. It is easy to append with any skin to accommodate any thickness. It is the most lightweight (1.5 lbs. per linear ft.), true flat and strongest insulated lumber ever invented.

2 Bamboo-style Sing 2×12 plank.

Why have we developed the Bamboo-style Sing 2 x 12 x 12 inch?

The only drawback when cutting 2 x 12 Sing Planks is exposing a portion of the Sing Core. When cutting the Sing 2×12 you need to remove a portion of the Sing Core and add insert a solid edge to end cap the exposed end. We have developed the solution by adding solid wood implants to create a Sing 2 x 12 like bamboo, providing cut points which will not expose Sing Core. It will have solid wood pre-installed at end of the Sing Panel cut point.

Due to the feedback of woodworkers who have heavy production schedules, we developed a new and improved Sing 2×12, that we call the Bamboo 2×12.

In much the same way that bamboo’s strength-cut-points occur naturally, Sing has scientifically redesigned the Sing 2×12 into its most prominent advancement, The Bamboo-style 2×12.

Sing-Bamboo-2x12-drawing-1You can see in the drawing (above) that 2 bamboo-like nodes have been put in place in the Sing 2×12 interior in the center-foot-area.
Cutting areas are precisely marked for your convenience. This allows for easy cross-cutting into lengths that are predetermined by the woodworking artist.


For instance, when cutting lengths of 1’, 3’, 4, 5’ or 8’ the nodes (or wood stiles) are pre-installed for convenient cross-cutting into these standard lengths.

Using the standard Sing 2×12, cutting an 8 foot length into two 4 foot lengths, would require the production team or woodworker to install wood styles at the cross-cut point, which may slow-down the production time.

Now, with the new and improved Bamboo-style 2×12, these challenges have been resolved, streamlining the production process


In the example (above) you can see how easy it is to edge-glue (using standard carpenter’s glue) Sing Bamboo 2x12s together into a large panel that could be used as a tabletop, counter, door, etc…

Question: If I need to build a door or table at 36 inch wide x 84 inch x 1.75 inch, what should I use Sing 2×12 plank or Sing Bamboo-style plank?

Answer: The Sing 2×12 Plank, because the Sing Bamboo-style 2×12 added cut-points would be superfluous (plus, the Sing 2×12 is less expensive).

Aesthetically, the Bamboo-style 2×12 and the Sing 2×12 look the same. If you require the Bamboo-style 2×12, you must specify when ordering.

Please examine the following table of Sing Core vs. all other types of cores (we use Balsa wood core instead other types of wood base core for comparison. Sing Core is about half of the weight of Balsa wood but at a fraction of the price). Sing Core is a revolution in lightweight, high strength core; the bottom line is low cost and high performance.

Insulation: Sing Core has built-in insulation value with an R3 to R6.5 rating per inch, depending on client’s needs/specifications.

Sound deadening: Sing Core’s filler material has natural sound-deadening properties. Other sound-deadening options are available at customer request.

Light weight: When compared to other materials Sing Core weighs much less, as much as 50% less, or more, as little as 4 lbs. per sq. ft. yet eco-friendly. This advanced technology used in the aviation industry is now available for use in your home.

Strength: Sing Core based on 2″ x 2″ grids and 3/4″ thick = 660 PSI. For instance, aluminum 3/8″ grids = 30+ PSI (smaller grids should be more strength). Sing Core’s superior strength comes from its advanced torsion box design.

Solid: Sing Core is solid like a rock. While the vertical wood grain torsion box core may be compared to other hollow honeycomb cores, the Sing Core voids are not hollow as they are bonded wall-to-wall and filled with recycled foam for a strong, solid substrate.

Eco-friendly: Sing Core is manufactured using natural wood fibers, no formaldehyde, or toxic chemicals, is created using less energy than any other core material with little or no waste.

Renewable: The structure of Sing Core is 100% renewable (nature-grown) clean fiber and/or recycled material.

Oversize: Sing Core excels in area of large oversize products due to its unique properties and can be up to 50 foot length.

Dimensionally stable: Sing Core is the most dimensionally stable building material allowing us to create large, oversize products (i.e., doors, up to 50 ft.) that are true flat exceeding AWI standards and can be guaranteed to be true flat. Large oversize panels can be truly dimensionally stable without any movement due to temperature and moisture change.

Affordable: Even though Sing Core technology is used in high-end applications, we make it affordable for broad use in a large number of applications. Sing Core performance is comparable to any high-end core but could be as little cost as low-end wood product core.

Waterproof upgrade: Sing Core is available in waterproof upgrade, to accommodate your specific water resistant requirements.

Fire retardant upgrade: When used in fire retardant applications, the Sing Core fire retardant door is the lightweight, super-strong, eco-friendly alternative.

Bullet-proof upgrade: In high-security end products, most cores used in bullet-proof applications are heavy in weight, causing strain on the infrastructure, unlike Sing Core.

Thickness available: Sing Core is readily available in many thicknesses, up to 6 inches in standard thickness, with custom thicknesses available.

Skin options: Available in many different exteriors including (but not limited to) aluminum, cement board, cold roll steel, concrete, ceramic tile, fiber glass, galvanize metal, glass, MDF, metal, plastic, plywood, solid wood, stainless steel, etc…

Easy to machine: Sing Core is easy to work with in the shop or on-site for sawing, sanding, adding solid wood implants, gluing, cutting and fastening.

Fast turnaround: In you’re in a rush, only Sing Core can be custom made within 24 hours and is proudly manufactured for you in the USA.

Our simple pricing method makes it easy for your sales team and customers to determine price based on volume, such as length, width, and thickness per board ft.
