Powder Coated Galvanized Metal Strut Channel Steel Unistrut Hot Dip 3m Support System

Products:

HOT DIPPED GALVANIZED (HG) is used for both Unistrut channel and fittings, this is the chosen finish for where applications will be in a severe corrosion setting. Galvanized channels are A36 hot rolled steel, or mild steel, channels that have been dipped into a molten zinc coating process (ASTM A123). Hot-dipped galvanize (HDG) can be identified by its crystallization pattern, also known as “spangle” on the surface of the material. Galvanized steel takes a long time to rust, but it will eventually rust. This type is carbon steel that has been galvanized or coated with a thin layer of zinc. The zinc acts as a barrier preventing oxygen and water from reaching the steel, providing advanced corrosion protection.

Features:

Galvanized steel offers excellent resistance against water and chlorine but pales in comparison to stainless steel's corrosion resistance when dealing with marine environments. The protective layer on galvanized is also not self-healing like the passive layer on stainless steel. Galvanized steel is standard steel that is coated in zinc to provide enhanced corrosion resistance. The galvanized protective coating protects the iron steel substrate from corrosion due to moisture, saturated environmental conditions, or ambient humidity.
