Zinc wire for arc spray coating is a high purity zinc material specially designed for electric arc spraying applications. During the arc spray process, zinc wire is continuously melted by an electric arc and atomized onto steel surfaces to form a protective zinc coating that provides excellent corrosion resistance.

Arc Spray Process Overview
Arc spray zinc wire is a consumable metal spraying material used in electric arc thermal spraying systems. During operation, two zinc wires are fed into the spray gun where an electric arc melts the zinc material. Compressed air atomizes the molten zinc and deposits particles onto prepared steel surfaces, forming a protective zinc coating layer that improves corrosion resistance and protects steel structures from environmental damage.
Key Applications
Bridge Corrosion Protection
Zinc arc spray coating is widely used for bridge maintenance and new construction protection of steel bridges, railway bridges, highway structures, and structural steel components. The zinc coating protects steel from rain, humidity and atmospheric corrosion.
Pipeline Surface Protection
Zinc wire coatings provide corrosion resistance for pipelines exposed to outdoor environments including oil pipelines, gas pipelines, water pipelines, and industrial pipelines.
Offshore and Marine Structures
Zinc coatings are suitable for marine environments where steel structures face saltwater corrosion, including offshore platforms, ship structures, port equipment, and marine steel components.
Industrial Equipment
Arc spray zinc coating improves corrosion resistance of industrial equipment including storage tanks, steel frames, machinery parts, and factory structures.
