Unistrut Channel Hot Dipped Galvanized
Unistrut Channel Hot Dip Galvanized (HDG) - the finished part is immersed in a bath of molten zinc.
This method results in complete zinc coverage and a thicker coating than pre-galvanized or plated zinc. The zinc coating is typically 2.6 MIL or 1.5 oz./sq. ft. of surface area.
Hot Dip Galvanised is the coating of choice of Unistrut Channel for applications where severe corrosion is a design factor.
