    Galvanized steel


    TECHNICAL PARAMETERS:


    DESCRIPTION:


    Galvanized steel pipe is a hollow square cross-section light thin-walled steel pipe, also known as steel refrigerated bending section. It is a section steel with a square cross-section shape and size made of Q235 hot-rolled or cold-rolled strip or coil as the base material, which is formed by cold bending and then high-frequency welding. Except for the increase in wall thickness, the corner size and edge flatness of hot-rolled extra-thick-wall galvanized steel pipes reach or exceed the level of resistance welded cold-formed galvanized steel pipes. The main welding process for welding galvanized steel pipes.

    Because the galvanized steel pipe is galvanized on the steel pipe. Galvanized steel pipes have a wide range of applications. They are mainly used in machinery manufacturing, curtain walls, construction, shipbuilding, steel construction projects, steel structure projects, solar power generation brackets, power engineering, agricultural and chemical machinery, power plants, automobile chassis, airports, etc.

    Advantages of galvanized steel pipe

    1. Hot-dip galvanizing has uniform coating, strong adhesion and long service life;

    2. Strong corrosion resistance;

    Application areas:

    Galvanized steel pipes are widely used in construction, machinery, coal mines, chemicals, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
