Galvanized pipe, also known as galvanized steel pipe, is a pipe coated with zinc layer on the surface of welded steel pipe, galvanized pipe is divided into hot galvanized pipe and cold galvanized pipe two main types. Hot dip galvanized pipe is formed by dipping the steel pipe into molten zinc, this treatment can produce a thick and uniform coating, with strong adhesion and long service life.

Galvanized steel pipe is a welded steel pipe with a hot dip plating or electric galvanized layer on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and extend the service life. Technological process is: the clarinet, alkaline cleaning, washing, pickling, rinse, leaching agent, drying, hot dip galvanized within the outer wind -air cooling, water cooling, passivation, water rinse, inspection, weighing, warehousing.

The manufacturing process utilizes a fully automated intelligent control system with digital monitoring from raw material pretreatment through continuous rolling and annealing treatment. Equipped with German-engineered 4-high reversible rolling mills and continuous annealing furnaces, we ensure consistent mechanical properties throughout each coil. Online non-destructive testing equipment provides real-time surface defect and microstructure inspection, while precision slitting units guarantee perfect coiling flatness. Our ISO9001-certified production involves 16 quality checkpoints from molten steel to finished products, ensuring uncompromising quality throughout the entire manufacturing process.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
