High Purity Zinc Wire for Thermal Spray Coating and Anti Corrosion Protection
High purity zinc wire is a specialized zinc material designed for thermal spray coating applications, including arc spraying and flame spraying. During the thermal spraying process, zinc wire is melted and atomized onto steel surfaces to form a protective zinc coating.
The zinc coating provides excellent corrosion resistance through both barrier protection and sacrificial anode protection. Even if the coating surface is damaged, zinc continues to protect the steel substrate by preferentially corroding before the base metal.
High purity zinc wire is widely used for corrosion protection of bridges, pipelines, offshore structures, storage tanks, steel frameworks and industrial equipment. Consistent zinc purity, accurate wire diameter and clean surface quality are essential factors affecting spraying performance and coating durability.
ZhenAn supplies high purity zinc wire with stable chemical composition, uniform dimensions and customized specifications to meet different industrial thermal spray requirements.

Applications of Zinc Wire
Zinc wire is mainly used as a thermal spray material for applying corrosion-resistant zinc coatings on steel surfaces. The sprayed zinc layer acts as a protective coating that extends the service life of metal structures exposed to moisture, chemicals and harsh environments.
Bridge and Steel Structure Protection
Zinc wire thermal spray coatings are widely applied on bridges and steel structures because zinc provides long-term corrosion resistance in outdoor environments.
- Steel bridges
- Railway structures
- Steel towers
- Industrial buildings
- Structural frameworks
Pipeline Corrosion Protection
Zinc coatings help protect pipelines from atmospheric corrosion and environmental exposure.
- Oil and gas pipelines
- Water pipelines
- Chemical industry pipelines
- Underground steel components
Marine and Offshore Applications
Marine environments contain high levels of moisture and salt, creating severe corrosion risks. Zinc wire coatings provide additional protection for offshore and marine equipment.
- Offshore platforms
- Ship components
- Port facilities
- Marine steel structures
Industrial Equipment Protection
Zinc thermal spray coatings are also used for industrial equipment requiring improved corrosion resistance.
- Storage tanks
- Pressure vessels
- Machinery parts
- Steel processing equipment
