Galvanized round pipe is suitable for most indoor and outdoor engineering and industrial applications. Hot dipped galvanized steel pipe is one of the most widely used metal anti-corrosion methods. It applies a thin coating of zinc to the thicker round tub
The hot dipped galvanized steel pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the round tube base and the coating are combined. Hot galvanized pipe has the advantages of uniform coating, strong adhesion and long service life.
The galvanized round pipe is galvanized on the round tube, so its application range has been greatly expanded compared with the square tube. Mainly used in curtain wall, construction, machinery manufacturing, steel structure engineering, shipbuilding, solar power generation support, steel structure engineering, electric power engineering, power plant, agricultural chemical machinery, glass curtain wall, automobile chassis, airport, etc.
Galvanized round pipe has the following production steps:
