1.weight calculated on the basis of 640 kg/m^3 (40 lbs/cu.ft.) density and nominal thickness.
2.15 mm (19/32 inch) thick and thicker are available in either square-edged or tongue-and-groove on the long edges.
3.thicknesses are available on special order.
The most common panel size is 1220 x 2440mm (4′ x 8′). Panels can also be made to a metric size of 1200 x 2400mm. Panels may be specially ordered up to 2440 x 7320mm (4′ x 24′). Larger panel sizes are desired by the manufacturers of wood I-joists because the long lengths reduce the need for web splicing.
Sizes smaller than the standard size can also be specially ordered.
Thicknesses are available from 6mm (1/4″) to 28.5mm (1-1/8″).
Panels may be sanded on one or both faces on special order.
