Trivalent blue zinc plating services provide a corrosion-resistant, environmentally friendly, and RoHS-compliant finish for metal components, commonly used in automotive, electrical, and industrial sectors. This electrolytic process deposits a zinc layer with a blue-tinted trivalent chromium passivation, often used on steel, brass, and aluminum for a durable, bright aesthetic.

Yellow passivation zinc plating is a corrosion-resistant coating process where zinc-plated metal is dipped in a yellow chromate solution, creating a protective, iridescent yellow-gold film. It offers superior corrosion protection compared to clear plating, making it popular for automotive parts, fasteners, and heavy-duty hardware
