ПРОГРЕСС
Q235 / Q345 welded round tube with thick zinc coating, engineered for fence, scaffold, green house and structural framing where corrosion resistance matters.
Hot-dipped galvanized round pipe is a welded carbon steel tube coated with zinc after fabrication (post-galvanized), providing sacrificial corrosion protection for outdoor and underground use. QIDAMT supplies a full range of ERW GI round pipe in BS EN / ASTM standard.
