Surface Treatment in marine environment

Surface Treatment in marine environment

Surface Treatment in marine environment

(OP)
Of Hot Dip Galvanising and Hot Zinc Spraying, which is typically the most effective surface treatment on carbon steel in a coastal marine environment in terms of impact resistance, adhesion and corrosion resistance?

Thanks,

RE: Surface Treatment in marine environment

HDG and zinc metallizing are both reasonably effective in a coastal environment. If the metallizing is sealed, I would give it the advantage.

RE: Surface Treatment in marine environment

I have no experience with zinc metallizing other than as a repair method for damaged galvanizing, but I don't think there is a substitute for hot dipped galvanizing. One of the beauties of HDG is that the thicker the steel, the thicker the protective layer of zinc which is deposited in the process.
