• Surface: smooth / oxide-controlled for stable arc spraying
• Application: thermal spray, metallizing, cathodic protection
• Performance: high deposition efficiency + uniform coating structure

99.99% high purity zinc wire is used to solve long-term corrosion failure in steel structures exposed to harsh environments such as marine atmosphere, humidity, industrial pollution, and underground conditions.

When applied through thermal spray or arc spray systems, zinc wire forms a sacrificial metallic coating that actively corrodes instead of the steel substrate. This electrochemical protection mechanism ensures that steel structures such as bridges, pipelines, wind towers, and offshore platforms maintain structural integrity over extended service life.

Compared with conventional coatings, high purity zinc wire reduces contamination risks and ensures more stable arc behavior, resulting in denser and more uniform protective layers.

Precise diameter control ensures stable wire feeding during arc spray and thermal spray operations. If wire diameter fluctuates, it can lead to unstable arc performance, uneven melting rate, and inconsistent coating thickness.

With a controlled range of 0.8–3.17mm, zinc wire maintains:

• Stable arc ignition and continuity
• Uniform melting rate
• Consistent spray deposition efficiency
• Reduced equipment wear and downtime

This is especially important in automated industrial coating systems used for large steel structures and continuous production lines.

Zinc wire provides active sacrificial protection, meaning it corrodes instead of steel when exposed to moisture, oxygen, or salt environments.

During thermal spraying, molten zinc particles form a dense coating layer that acts as both:

• A physical barrier against corrosive agents
• An electrochemical sacrificial layer

This dual protection significantly improves service life of:

• Bridges and highways
• Offshore platforms
• Wind turbine towers
• Industrial steel frameworks
• Storage tanks and pipelines

High purity zinc ensures consistent coating behavior, reducing weak points that could lead to localized corrosion.

99.95% zinc wire is commonly used in standard corrosion protection systems, while 99.99% zinc wire is preferred for high-spec engineering projects requiring maximum coating reliability and long-term durability.

The higher purity level significantly improves coating performance in aggressive environments such as seawater exposure and high humidity zones.

Modern thermal spray systems require stable arc behavior, controlled melting rate, and consistent wire feeding performance. High purity zinc wire minimizes interruptions caused by impurities that can destabilize the arc process.

Key advantages include:

• Reduced oxidation during spraying
• Improved coating adhesion
• More uniform protective layer formation
• Lower equipment maintenance requirements
• Higher overall coating efficiency

Yes, zinc wire can be fully customized based on application requirements.

Customization options include:

• Diameter (0.8mm – 3.17mm)
• Purity levels (99.9% – 99.995%)
• Spool size and coil weight
• Surface finish control
• Packaging for export logistics
• OEM labeling and branding

This flexibility allows zinc wire to meet different standards in marine, energy, construction, and heavy industry applications.

99.99% high purity zinc wire plays a critical role in thermal spray corrosion protection systems for steel structures. With precise diameter control, ultra-low impurities, and stable feeding performance, it ensures long-term protection in demanding environments such as offshore, marine, and industrial infrastructure.

It is a key material for engineers and procurement teams seeking reliable, long-life corrosion protection solutions.

Because higher purity improves arc stability, coating uniformity, and long-term corrosion resistance performance.

Most common sizes are 1.6mm, 2.0mm, and 3.17mm depending on spray equipment and coating requirements.

Yes. 99.99% zinc wire is widely used in offshore platforms due to its strong corrosion resistance performance.

Both use zinc wire as feedstock, but arc spray uses electrical arc melting, while thermal spray may include different heating mechanisms.

It forms a sacrificial coating that corrodes first, preventing steel from rusting and extending structure lifespan.

Yes, zinc wire is commonly supplied in spools for automated industrial spraying systems.
