Process and characteristics.

– Process: High-frequency welding → Rounding and shaping → Acid washing and phosphating → Hot-dip galvanizing (at temperatures above 450°C).

– Advantages:

– ✅ High Strength: More resistant to bending and deformation than a wall thickness of 1.1 mm.

– ✅ Corrosion resistance advantage: The hot-dip galvanized layer is dense, and it can withstand salt fog for ≥1200 hours without developing red rust.

– ✅ Flame-resistant grounding: Metal material is non-combustible and highly conductive, with a high safety rating.

– ✅Easy installation: Ports have no burrs, allowing for manual bending of tubes and precise connections.
