Description
A soft, red coastal tree, Sequoia sempervirens, found within 30 miles of the Pacific coast in northern California and southern Oregon. Redwoods are the tallest living trees and soome are more than 2000 years old. The redwood tree produces of lightweight, spongy wood that has a straight grain. The strong, durable wood is used for bridges, boxes, lumber, shingles, siding, fencing, and decking. Natural tannin dyes in the wood tend to cause brown stains in paint films. Redwood is resistant to decay and insect attack. It significantly expands and contracts with changes in humidity. Peak lumbering years were 1910-1930.
