Why use ProWood pressure-treated lumber?Lumber's greatest enemy is biological attack — destruction by termites, fungi and marine borers — as well as damage from rain, sun and wind. Thanks to over 50 years of research, ProWood can stand up to every threat for decades of use.

How do I know if the treated wood I'm using is properly treated for my intended use?Look for a lumber end tag. Each piece of ProWood lumber has a tag containing information regarding the preservative used, the appropriate end use (i.e. above-ground or ground contact), the quality standard and safe handling instructions.

Is ProWood pressure-treated wood building code approved?You should always consult your local building codes before application. When working with ProWood pressure-treated decking, lumber and timbers, you'll want to locate the double-box symbol on the end tag. The double-box symbol is required for building code compliance; indicating the standard authority and the third party inspection agencies. Generally, ProWood decking, lumber and timber products will carry the double-box symbol demonstrating that they are code compliant when used in the right application.
