The main difference between trivalent chromium white zinc and white zinc lies in their processing technology, color performance, and application scenarios. The following is detailed information:

Processing technology. White zinc plating is a surface treatment technique that typically involves electroplating zinc by electrodepositing zinc in an electrolyte. Trivalent chromium electroplating is a treatment process that protects the surface of a metal and improves its appearance by coating it with a layer of trivalent chromium compound.

Color representation. The color of white galvanized steel appears white, which is due to the absence of pigments during the coloring process of the galvanized surface, and the high reflectivity of the zinc layer. The color of trivalent chromium usually appears silver white or dark gray, which is due to the trivalent chromium compound adhering to the metal surface to form a layer of ceramic like oxide layer.

Application scenarios. White galvanizing is more suitable for surface treatment of products that require a white appearance, such as household items, electrical enclosures, etc. The surface color of trivalent chromium treatment usually presents silver white or dark gray, which is more suitable for surface treatment of products that require high-end, aesthetic, and anti-corrosion performance, such as automotive parts, kitchen and bathroom products, etc.
