WebUnfortunately, coating projects over hot dipped galvanizing can be challenging. When you compare all the procedures, inspection, testing, cleaning, profiling, etc., with the application of a shop-applied zinc-rich primer, the choice becomes clear. Unless the galvanized metal is not going to be coated, the better choice is to use a zinc-rich primer. WebThe hot-dip galvanizing process is an inter-diffusional mixing of iron and zinc, forming a multilayer coating on the steel hardware’s surface. The iron and zinc diffusion creates intermetallic layers that form perpendicular to the steel surface and give a uniform coating on all steel surfaces. When galvanizing structural bolts, zinc metal ...
