99.99% high purity zinc wire is an industrial thermal spray material manufactured under ASTM quality standards for long-term corrosion protection of steel structures. It is widely used in bridge engineering, offshore platforms, storage tanks, transmission towers, and industrial infrastructure.
During thermal spraying, molten zinc particles form a dense sacrificial coating on steel surfaces, protecting the base metal from oxidation, salt spray, and industrial corrosion.

Thermal spray zinc coatings act as a sacrificial barrier. Even if the coating surface is scratched, zinc corrodes first and protects the steel underneath.
This protection mechanism significantly extends the service life of:

• bridges
• offshore steel platforms
• transmission towers
• industrial pipelines

99.99% high purity zinc wire provides:

• stable arc spraying performance
• lower impurity interference
• smoother coating formation
• improved corrosion resistance

High purity also reduces oxidation during spraying.

Large steel structures are continuously exposed to:

• rainwater
• humidity
• salt spray
• industrial pollution

Thermal sprayed zinc coating creates a long-lasting anti-corrosion layer with lower maintenance costs than conventional painting systems.

99.99% zinc wire contains fewer impurities and offers:

• more stable arc performance
• denser coating structure
• better corrosion resistance in marine environments

99.9% zinc wire is more economical for standard industrial projects.

2.0mm zinc wire is suitable for medium-output spraying systems and precision coating control.

• higher deposition efficiency
• faster coating speed
• large-scale bridge coating projects

ASTM standard zinc wire ensures:

• controlled chemical composition
• stable diameter tolerance
• reliable coating consistency
• international engineering compliance

Non-standard products may create unstable spraying conditions.

Steel bridges require durable zinc metallizing systems to withstand outdoor exposure for decades.

Marine structures use thermal spray zinc coatings to resist saltwater corrosion and humidity.

Storage tanks, steel frames, and power facilities depend on zinc coatings for long-term protection.

99.99% high purity ASTM standard zinc wire is a premium anti-corrosion material widely used in thermal spray systems for bridges and steel structures. Its high purity, stable spraying performance, and strong sacrificial protection capability make it an essential industrial material for long-term infrastructure protection.

It is mainly used for thermal spraying and anti-corrosion coating of steel structures.
