Sitka spruce (Pinus sitchensis) is used in a variety of structural products. High grades are popular for specialty marine applications such as masts, spars and deck beams, and for ladder stock and industrial equipment where a high strength-to-weight ratio is desired.

In North America, structural grades are in accordance with National Lumber Grades Authority (NLGA) rules for dimension lumber. Sitka spruce is currently marketed under the Northern Species group.
