Zinc Spray System FAQs

What is a Zinc Spray System?

A Zinc Spray System is a thermal spraying machine that melts zinc (typically in wire or powder form) and sprays it onto metal surfaces using compressed air. It is mainly used for anti-corrosion protection, especially on weld seams of steel pipes and structural components.

How does arc zinc spraying work?

Arc zinc spraying uses two zinc wires fed through a spray gun where an electric arc melts the wire tips. Compressed air then atomizes and propels the molten zinc onto the target surface to form a protective coating.

What materials can be sprayed?

Primarily pure zinc or zinc-aluminum alloy wires. Some systems may also support aluminum or other corrosion-resistant metals.

What surface preparation is needed before spraying?

Typically, abrasive blasting (e.g., SA 2.5 standard) is required to remove rust, scale, and oil, ensuring good adhesion of the zinc coating.

How thick is the typical zinc coating?

Common zinc coating thickness ranges from 30 to 120 μm, depending on the corrosion protection requirement and application.
