A. Hi Ashtabhuja. Hot dipping can be specified to ASTM A123
[affil. link], zinc plating (electrogalvanizing) to ASTM B633
But cold rolled lip channels are used in 1001 applications so there is no single appropriate finish. In fact, pregalvanizing is probably not acceptable for some of those applications. Where are these channels going and for what purpose? Thanks.
