ASTM A36 40X40 Carbon Steel Profile square pipe

1. ASTM A36 40X40 Carbon Steel Profile square pipe Specification & Description

(1) square tube product description
Square tube is a hollow square cross section light thin wall steel tube, also known as refrigeration bending steel profiles. It is based on Q235 hot rolled or cold rolled steel strip or rolled plate parent metal by cold bending forming by high frequency welding again after made of square cross section shape, the size of the steel. Hot rolled, thick-walled square tube in addition to outside in the thickness of the wall thickness, the size and edge Angle straightness achieves even exceed the level of the resistance welding cold forming square tube. Good comprehensive mechanical performance, weldability, cold and hot working performance and corrosion resistance are good, good low temperature toughness.
(2) square tube usage
The purpose of the square tube construction, machinery manufacturing, steel construction projects, shipbuilding, solar power stents, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain wall, automobile chassis, airport, the boiler construction, highway railings, housing construction, pressure vessel, oil tank, bridge, power station equipment, lifting transportation machinery and other high load of welded structure, etc.
