First of all, the cost of galvanizing screws is low, and the galvanized layer has high anti-corrosion ability and is not easy to rust, but it cannot maintain the original luster for a long time, and the cost of chrome plating for screws is high. The protective ability of the chrome plating layer is not as good as that of the galvanized layer, but the chrome plating is more wear-resistant and can maintain the original luster for a long time. For screw fasteners that need to be exposed, it is recommended to choose a decoration that has a bright appearance and is more wear-resistant.
