Sitka spruce (Pinus sitchensis) is used in a variety of structural products. Because it is stronger than the same weight component made of steel, Sitka spruce is used in building airplane framework components. It has virtually no odour or taste so is suitable for food storage and processing.
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. The wood has excellent acoustic properties and is used to make sounding boards in pianos and other musical instruments such as violins and guitars.
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.
