Product Overview
Hot dip galvanized steel pipe, also known as GI pipe, is manufactured by ERW high-frequency welding or seamless forming, then immersed into molten zinc liquid for full hot-dip galvanization. A tight zinc-iron alloy layer forms on the pipe surface to isolate air and moisture, delivering long-term anti-rust and anti-corrosion performance.Main raw materials are Q195 and Q235 low carbon steel, complying with ASTM A53 and GB/T3091 standards. Widely adopted in construction scaffolding, fire protection water supply, agricultural greenhouses, municipal plumbing, fence posts and solar support systems. Our factory owns complete production lines, sufficient spot inventory and customizable processing services for global bulk buyers.
