ELECTRO-GALVANISING PROCESS
Galvanising is the covering of a piece of metal in a zinc bath to protect it from corrosion as well as giving i tan improved appearance.
Various methods are employed. small parts are galvanised in bulk in rotating drums, while for the larger sizes necessary for our cages, a frame is used to reduce surface friction on the material. In this case, the piece is cleaned and hung off a frame designed for this purpose. After the electrolytic bath a covering thickness of 6-12 microns is achieved
