Laocheng Mingxing Pipe Industry Manufacturing Co., Ltd. produces galvanized welded steel pipes that combine structural integrity with corrosion protection. These pipes are manufactured by welding high-quality carbon steel strips into round, square, or rectangular shapes, followed by a galvanization process to apply a protective zinc layer. The welding process uses advanced techniques (ERW, SAW) to ensure strong joint quality, while the zinc coating (hot-dip or electro-galvanized) provides excellent rust resistance for outdoor and humid environments. They are widely used in water supply systems, construction scaffolding, gas pipelines, and agricultural irrigation due to their reliable pressure resistance and easy installation. The company adheres to strict standards in material selection, welding parameters, and galvanization quality, with each pipe undergoing hydrostatic pressure testing, non-destructive flaw detection, and coating thickness measurement. Offering a full range of sizes and specifications, these galvanized welded steel pipes provide cost-effective solutions for diverse infrastructure and industrial needs.
