What is ZMAX®?
ZMAX® is a thicker coating (galvanized per ASTM A653 with a G185 coating) than the standard hot-dip galvanized coating (galvanized per ASTM A653 with a G90 coating). This thicker coating is available on select Simpson Strong-Tie connectors. Due to this increased galvanized thickness these connectors would be expected to have a longer service life than standard galvanized connectors. See Simpson Coatings Available for additional information.
