Zinc Yellow Trivalent
Zinc Yellow Trivalent is a corrosion-resistant finish where metallic zinc is first deposited on the fastener’s surface through electroplating. This is followed by a yellow trivalent chromate treatment that enhances corrosion protection while meeting environmental and safety standards. It provides a safer alternative to traditional hexavalent finishes.
Appearance - Fasteners with this finish have a bright yellow or gold color, often showing iridescent hints of green, pink, or purple depending on the lighting. Generally, fasteners with a Zinc Yellow Trivalent finish have a less vibrant color compared to traditional hexavalent Zinc Yellow finishes.
