Galvanized Steel Pipe Fittings & Flanges

Hot Dipped Galvanized

Hot dip galvanizing (HDG) is a process in which steel flanges are submerged in molten zinc at a temperature of 850F.  During this process, the molten zinc reacts with the steel to form thin layers of zinc alloys.  These layers form a barrier that can provide exceptional corrosion protection compared to more traditional methods.  This helps to increase the life and productivity of each flange.

Kerkau hot dip galvanized flanges and fittings come with extra deep stamping for ease of identification.  All threading is done after galvanizing to ensure quality of thread.
