Common Uses

Construction and framing, plywood, heavy timber construction, flooring, doors, and veneer.

Geographic Origin

Western North America and the Pacific Northwest

Workability

Generally works well with both hand and machine tools, though the sharp contrast in density between earlywood and latewood can occasionally cause uneven planing or sanding if tools are not kept sharp.

Finish Recommendations

Accepts stains, varnishes, and polyurethanes very well; conditioning may be required for uniform staining due to density variations.

Notable Features

High strength-to-weight ratio, distinct resin canals, and a characteristic sweet or resiny scent when freshly cut.
