Product Description
Galvanized square pipe is a common building material, its production process is mainly through a series of chemical reactions in the hot dip galvanizing pool to make the steel plate or steel strip forming, can also be made through hot-rolled or cold-rolled galvanized steel strip after cold bending, and then high-frequency welding made of hollow square cross-section steel pipe. The production process of galvanized square pipe is relatively simple, high production efficiency, more varieties and specifications, less equipment investment, but its strength is generally lower than the seamless square pipe.
Galvanized square pipe has good strength, toughness, plasticity and welding and other process properties, as well as good ductility. In addition, the zinc layer covering its surface can effectively prevent the square steel pipe from coming into contact with the external environment, so it has excellent corrosion protection. This makes the application range of galvanized square pipe has been greatly expanded compared with square pipe.
In practical use, galvanized square pipe is mainly used in curtain walls, buildings, machinery manufacturing, steel construction projects, shipbuilding, solar power generation brackets, steel structure projects, power projects, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports and other fields. For example, it can be used as pipeline pipe for water, gas, oil and other general low-pressure fluids, and can also be used for oil well pipe and oil pipeline in marine oilfield, oil heater, condensation cooler, coal distillation washing oil exchanger pipe for chemical coking equipment, and stack bridge piles, support frame pipe for mine pits and so on.
