Zinc Thermal Spray Wire 1.2 mm

Zinc Wire for Arc and Flame Spray Coating

Thermal spraying with zinc wire is a widely accepted method for providing long-term galvanic protection without the size limitations of hot-dip galvanizing. The 1.2 mm diameter is a common standard for many arc spray guns, offering a good balance between feedability and deposition rate. The resulting coating acts as a sacrificial anode, corroding preferentially to protect the underlying steel.

This wire is suitable for on-site coating of welded joints, shop-applied corrosion protection on structural steel, and restoration of damaged galvanized surfaces. The process generates a clean, metallic coating that can be left as-sprayed or sealed with a compatible topcoat for extended service life in aggressive environments.

Key Features and Benefits

• Sacrificial protection: Provides active galvanic corrosion protection for steel substrates, even if the coating is scratched or damaged.
• Standard diameter: 1.2 mm wire is compatible with a wide range of common arc and flame spray equipment, simplifying procurement.
• Flexible pack sizes: Available in 15 kg, 20 kg, and 25 kg spools, plus coil packs, allowing users to match the packaging to their job size and equipment pay-off system.
• On-site application: Enables field coating of large or fixed structures that cannot be dipped in a galvanizing bath.

Typical Applications

This zinc wire is specified across industries where steel corrosion is a primary concern. Common applications include:

• Structural steel: Coating of bridges, towers, and building frameworks for long-term atmospheric corrosion protection.
• Storage tanks: External and internal (non-immersion) coating of water and fuel storage tanks.
• Marine and offshore: Protection of ship hulls, decks, dock gates, and offshore platform components in saltwater environments.
• Ductile iron pipe: Applying a zinc layer to ductile iron water pipes as a standard corrosion barrier.
• Galvanizing repair: Restoring corrosion protection on welded or damaged areas of galvanized steelwork.

Selection and Handling Tips

To get the best results, confirm that your spray system is set up for 1.2 mm wire. Check the condition of drive rollers, contact tips, and wire guides to ensure smooth, consistent feeding. Store wire spools in a dry, covered area to prevent surface oxidation or contamination that could affect spray quality. The wire surface should be clean and free from drawing lubricants for optimal arc stability and coating adhesion.

When requesting a quotation, it helps to specify the required pack type (spool or coil), pack weight, and the spray process you intend to use. This allows us to confirm compatibility and offer the most practical packaging option for your project.
