It equals the volume of a board that is one foot (30.5 cm) in length, one foot (30.5 cm) in width, and one inch (2.54 cm) in thickness, or exactly 2.359 737 216 liters. Board foot can be abbreviated as FBM ...
Re-sawing is the splitting of 1-to-12-inch (25–305 mm) hardwood or softwood lumber into two or more thinner pieces of full-length boards. For example, splitting a 10-foot-long (3.0 m) 2×4 ( 1 + 1 ⁄ 2 by 3 + 1 ⁄ 2 in or 38 by 89 mm) into two 1×4s ( 3 ⁄ 4 by 3 + 1 ⁄ 2 in or 19 by 89 mm) of the same length is considered re-sawing.
Engineered lumber can be cut to length and installed much like sawn lumber; the flitch requires shop fabrication and/or field bolting. This, coupled with a much increased self-weight of the beam (11.4 pounds (5.2 kg) for engineered wood vs. 25.2 pounds (11.4 kg) for a flitch beam), decreases the viability of the system.
A PSL block. Parallel-strand lumber (PSL) is a form of engineered wood made from parallel wood strands bonded together with adhesive. It is used for beams, headers, columns, and posts, among other uses. The strands in PSL are clipped veneer elements having a least dimension of not more than inch (6.4 mm) and an average length of at least 300 ...
In the United States, planks can be any length and are generally a minimum of 2×8 (1 + 1 ⁄ 2 in × 7 + 1 ⁄ 4 in or 38 mm × 184 mm), but planks that are 2×10 (1 + 1 ⁄ 2 in × 9 + 1 ⁄ 4 in or 38 mm × 235 mm) and 2×12 (1 + 1 ⁄ 2 in × 11 + 1 ⁄ 4 in or 38 mm × 286 mm) are more commonly stocked by lumber retailers.
When testing wood in lumber form, the Janka test is always carried out on wood from the tree trunk (known as the heartwood), and the standard sample (according to ASTM D143) is at 12% moisture content and clear of knots. [3] The hardness of wood varies with the direction of the wood grain. Testing on the surface of a plank, perpendicular to the ...
