Square Steel Pipe

Introduction of Square Cross Sections Steel Pipe:
Taking hot rolling steel and cold rolled steel strip as raw material, passing the bending process and the high-frequency welding, we manufacture the square cross sections steel. It is also known as the square steel pipe. The hot rolling square steel pipe has a much thicker wall, in addition, the size of its corner and the straightness of its edge are all reach of even surpass the standard of cold electric resistance welding. Application fields: construction, mechanical manufacture, steel construction project, shipbuilding, solar power stents, steel structure work, power engineering, electricity generating station, agricultural and chemical machinery, glass block screen wall, automotive chassis, airport, boiler construction, highway railing, housing construction, etc.

Main Component:
Raw material: strip steel.

Note:
1.It is applied in accordance with the customer's specific circumstances.
2.For fear of rusting in the long time ocean shipping, the steel pipes are all sprayed anticorrosive paint before exporting.
