◆ Anti-corrosion ◆ Multi-scenario Fluid Conduit ◆ Structural Rigidity
Product Overview
Hot-dip galvanized welded steel pipes made from Q235B/ASTM A53 steel strips. Uniform zinc coating (80-275g/m²) on both inner/outer surfaces provides superior corrosion resistance and mechanical strength. Ideal for indoor/outdoor corrosive environments like plumbing systems, construction scaffolds, and greenhouse frameworks.
