What are the newer types of pressure treated lumber? Are there any specific products I need to use with them?
The newer types of pressure treated lumber are less environmentally toxic; ACQ Alkaline Copper Quat, Copper Azole, and Borate treated products. To avoid electrolysis and accelerated oxidation, Simpson triple coated zinc (Z-MAX), Hot dipped galvanized, and stainless steel connectors and fasteners are recommended and available in the store.
