3-In-1 Grey Zinc protects, matches and seals all in one easy step.
Grey Zinc is a zinc rich coating containing metallic zinc which protects steel from corrosion. The metallic zinc is sacrificed in the preference to the steel, therefore ensuring long term protection.
Grey Zinc is ideally suited for touch up welds and damaged structures or components.
In highly corrosive environments, Silver Zinc Supplies’ Grey Zinc Cold Galvanizing Primer is recommended as an undercoat to provide long-term rust protection.
