Zinc Wire for Thermal Spray Coating and Surface Protection
High purity zinc wire used as corrosion resistant material in thermal spray coating and surface protection applications. Through arc spraying or flame spraying processes, zinc wire is melted and deposited onto metal surfaces to create protective zinc coating layers.
Product Overview
Zinc wire provides protective coatings through barrier protection and sacrificial protection, preventing direct exposure to moisture, oxygen, and corrosive environments while offering electrochemical protection to reduce corrosion damage.
High purity zinc wire is commonly used for protecting bridges, pipelines, offshore structures, storage tanks, steel frameworks, and industrial equipment. Stable chemical composition, uniform diameter, and clean surface quality ensure consistent coating performance.

Thermal Spray Process
Zinc wire for thermal spray coating is a specialized metal wire used as coating material in surface protection processes:
- Zinc wire is continuously fed into spray equipment
- Heat melts the zinc material
- Compressed air atomizes molten zinc particles
- Zinc particles are deposited onto prepared metal surfaces
- Protective zinc coating is formed
The resulting coating provides corrosion resistance and improves service life of steel structures in demanding environments.
