WebThe zinc thickness achieved by HDG is in the range of 2-to-8 mils for many steels and is dependent on immersion time in the bath. However, an HDG thickness in the range of 20-to-30 mils can be achieved with some reactive steels. The HDG process creates a dense coating of zinc that is metallurgically bonded to the steel surface.

Sydney. Posts. 13,956. The biggest problem to paint hot dip galvanised steel is the post galvanised treatment given to every HDG part unless you ask the galvaniser not to. Once taken out of the zinc bath the part is quenched in a chromate bath. It is this coating that interferes with the paint adhesion when freshly galvanised.
