GoldGalv: All surfaces are protected with a trivalent chromium finish applied over zinc, creating a chemically bonded non-porous barrier. GoldGalv finishes are applied after cutting and punching which protects all surfaces of the finished product.
SilverGalv: All surfaces are electro-plated with 0.5 mils of zinc after cutting and punching, providing a durable, corrosion resistant product. SilverGalv corrosion resistance is between that of Gold Galv, and Hot Dipped Galvanized products.
Hot Dipped Galvanized: The material is zinc coated after fabrication, providing total product protection on all surfaces.
Pre-Galvanized: A zinc coating is applied by hot dipping the steel at the mill prior to fabrication.
