The standard GoldGalv® finish metal framing channel is made up of a multi-step electro galvanizing and zinc dichromate process. The trivalent chromium finish is applied over the zinc, producing a chemically bonded non-porous barrier for protection from moisture and air. The 0.5 mil electro-plated zinc and gold trivalent chromium finish provide all of the features and protection of hexavalent chromium without the use of the chemical.
