3604-16 Galvanizing or tinning - not electrolytic, N.O.C.

     Applies to establishments engaged in providing galvanizing or tinning services, not using an electrolytic method, that are not covered by another classification (N.O.C.). This process uses molten zinc or tin dip to coat metals to deter corrosion (galvanizing) and tarnish (tinning). The process is used on all types of metal products from hand tools to automobile body parts and pieces of machinery. Work contemplated by this classification includes, but is not limited to, preparing metal by cleaning and washing in an acid solution, flushing with clean water, dipping in a metallic solution, immersion in the molten zinc or tin, and draining and/or blowing away the excess to achieve a smooth finish before cooling.

     This classification excludes galvanizing or tinning using an electrolytic process which is to be reported separately in classification 3603-11 and any galvanizing or tinning operations conducted in conjunction with a metal or metal product manufacturing operation which is to be reported separately as appropriate to the product.
