St52 A178 A53/304 316 347 Welded Square/Rectangular Tube

Short Description:

Product presentation:

Square pipe is a hollow square cross section light thin-wall steel pipe, also known as steel refrigeration bending profile. It is a hot rolled or cold rolled strip or coil as the base material by cold bending processing and then made of high frequency welding square section shape size of the steel. Except for the wall thickness and thickening, the corner size and the smoothness of the side all reach or even exceed the level of the resistance welded cold forming square pipe. Comprehensive mechanical properties, weldability, cold and hot machining properties and corrosion resistance are good, with good low temperature toughness.

Pipe use of construction, mechanical manufacturing, steel construction projects, shipbuilding, solar power support, steel structure engineering, electric power engineering, power plant, agriculture and chemical machinery, glass curtain wall, car chassis, airport, boiler construction, highway railings, housing construction, pressure vessels, oil storage tanks, Bridges, power station equipment, lifting transportation machinery and other higher load of welding structure, etc.
