Wolmanized® CCA Heavy Duty™ wood is timbers, posts, or plywood that is pressure treated with CCA preservative to provide protection from termites and fungal decay. The chemical used to preserve Wolmanized Heavy Duty pressure treated wood is a mixture of the oxides of copper, chromium, and arsenate known as CCA. Learn more about CCA. For 75 years, CCA-treated wood has been specified in a wide variety of applications; as of December 31, 2003, this wood may be produced only for listed uses. When used as recommended, CCA-treated wood is harmless to people, plants, and animals.Its use provides environmental benefits as well as decades of service.

This includes wood that will be in contact with water, soil, concrete or masonry, subject to periodic wetting, or exposed to moisture or high humidity. For more technical information on Wolmanized Heavy Duty wood, such as explanation of CCA and how it works, fixation, retention and penetration, and heartwood versus sapwood, download the Wolmanized Heavy Duty Wood Specification Guide.
Recommended Hardware Fasteners should be corrosion-resistant, such as: hot-dipped galvanized, copper, silicon bronze, stainless steel 304 and 316 or other metals having corrosion resistance equal to that of hot-dipped galvanized. Aluminum is subject to corrosion and should not be used in direct contact with CCA treated wood.
