Chromated Copper Arsenate (CCA)
Pressure-Treated Wood
Of all the wood products found in your local lumber yard, none has shown a more spectacular rise in popularity during the last 20 years than CCA pressure-treated wood. In 1976, it was a poorly understood material that was rarely, if ever, stocked by any Canadian yards; now it is unusual to find a dealer in North America who does not carry a generous assortment of decking, fencing and landscaping posts and timbers, much of it carrying a 40-year warranty against rot and insect attack.
