What does wolmanized mean?

"Wolmanized" refers to wood that has been treated with a chemical process developed by Dr. Herbert Wolman to protect it from decay, insects, and other environmental factors. This treatment typically involves the use of copper-based preservatives, which help enhance the wood's durability and longevity, making it suitable for outdoor use in applications like decking, Fencing, and utility poles. The term is often associated with pressure-treated lumber that meets specific standards for resistance to rot and pests.
