Zinc rich cold galvanizing is highly resistant to all forms of corrosion. Through galvanic action, small scratches "heal" themselves. Perfect where factory galvanized finish is damaged in shipment, assembly, welding, etc. Blends well with hot-dip coating. Forms a zinc film that by electro-mechanical reaction literally fuses itself to iron, steel and aluminum.
