The Zinc Spray System is a thermal spraying device that melts zinc wire or powder and sprays it onto metal surfaces using compressed gas. It is primarily used to coat weld seams and metal surfaces with a dense zinc layer to prevent corrosion and rust, especially on steel pipes and tubes.
Features and Benefits of Zinc Spraying on Rectangular/Square Tube Weld Seams
Features:
-
Designed specifically for automatic zinc spraying on square and rectangular tube weld seams
-
Uses arc spray technology suitable for continuous production lines
-
Automatically locates the weld seam for precise coating
-
Adjustable coating thickness to meet various protection requirements
Benefits:
-
Improved Corrosion Resistance at Welds: The zinc layer protects the seam from rust, greatly extending service life.
-
Reduced Post-Processing Costs: Automated zinc spraying replaces manual touch-up, increasing efficiency.
-
Uniform Appearance: Consistent zinc coating improves the visual and quality uniformity of weld seams.
-
Meets Export Standards: Zinc-coated welds comply with international anti-corrosion standards for steel structures.
