Dimensional lumber is lumber that is cut to standardized width and depth, often specified in millimetres or inches (but see below for information on nominal dimensions vs. actual dimensions). Carpenters extensively use dimensional lumber in framing wooden buildings.
Note: see dimensional lumber for a full discussion of the relationship of actual and nominal dimensions. Briefly, for softwoods, to convert nominal to actual, subtract 1 ⁄ 4 inch (6 mm) for dimensions under 2 inches; subtract 1 ⁄ 2 inch (13 mm) for dimensions over 2 inches and under 8 inches; and subtract 3 ⁄ 4 inch (19 mm) for larger ...
The exact volume of wood specified is variable and depends on the type of lumber. For planed lumber the dimensions used to calculate board feet are nominal dimensions, which are larger than the actual size of the planed boards. See Dimensional lumber for more information on this.
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. It is used for beams, headers, columns, and posts, among other uses.
In North America, the nominal voltage is 120 V, with variance allowed from 114 V to 126 V (±5%). Voltage is also supplied at 208 V, 240 V and 480 V with similar tolerances. In general, electrical devices are designed to work with one nominal voltage, which represents a band of possible actual voltages, power factor and AC waveform shapes.
That, coupled with interest rate cuts that could stoke lumber demand, will likely lead lumber futures prices to a range between $500 and $600, or slightly above pre-pandemic levels, according to ...
