Zinc Spray System – Smart Protection for Steel Pipes and Structures

The Zinc Spray System is more than just a coating machine – it is your steel’s shield against corrosion. Instead of dipping products into molten zinc, this system uses a high-speed spray gun to melt zinc wire or powder and apply it directly onto the surface. The result? A smooth, strong, and long-lasting zinc layer that keeps rust away even in the toughest environments.

How the Zinc Spray System Works

1. • Surface Preparation – The steel surface is cleaned and treated to ensure excellent adhesion.

2. • Zinc Feeding – Zinc wire or powder is continuously fed into the thermal spray gun.

3. • Melting Process – The zinc is melted using either a flame spray or electric arc method.

4. • Atomization – Compressed air breaks the molten zinc into fine particles.

5. • Spraying – The particles are propelled onto the steel surface, instantly solidifying into a protective zinc coating.

This process produces a mechanical bond that is extremely durable and resistant to cracking, peeling, or flaking.

Key Features & Benefits

• ✦Superior Corrosion Resistance – Protects steel products for decades in even the harshest environments.

• ✦Uniform Coating Thickness – Adjustable based on customer and industry requirements.

• ✦High Adhesion Strength – Zinc coating fuses tightly to the surface for long-lasting durability.

• ✦Eco-Friendly Solution – No acid baths or heavy chemical use; reduced zinc waste.

• ✦Flexible Application – Works on pipes, plates, and complex-shaped products that cannot be dipped.

• ✦On-Line or Off-Line Use – Can be integrated into a pipe production line or used as a standalone process.

Applications Across Industries

The Zinc Spray System is widely used in industries where corrosion resistance is critical:

• Pipe and Tube Manufacturing
  – ERW pipes, seamless tubes, and welded pipes for construction and fluid transport.

• Construction & Infrastructure
  – Bridges, highway guardrails, power transmission towers, and steel structures.

• Marine & Offshore Industry
  – Ships, oil platforms, underwater pipelines, and port facilities exposed to saltwater.

• Automotive & Machinery
  – Components that require long-lasting protection and reduced maintenance costs.

• Maintenance & Repair
  – Recoating corroded or damaged steel without dismantling the structure.

Why Choose Zinc Spray Instead of Hot-Dip Galvanizing?

The Zinc Spray System is not just an alternative—it is often a better choice for modern manufacturing.
