About Square Steel Pipe
The square tube is divided according to the production process: hot rolled seamless square tube, cold drawn seamless square tube, extruded seamless square tube, welded square tube. Among them, the welded square tube is divided into:
- (a) According to the process-arc welding square tube, resistance welding square tube (high frequency, low frequency), gas welding square tube, furnace welding square tube
- (b) According to the weld seam-straight seam welded square tube, spiral welded square tube
Product Specification
Square Steel Tube is a welded structural grade tubing that is available in either type A513 or A500 Grade B, depending on its size and wall thickness. Either grade is ideal for all structural applications, general fabrication, manufacturing and repairs. Steel Square Tube is widely used in industrial maintenance, agricultural implements, transportation equipment, truck beds, trailers, frames, etc. Its box-shape configuration allows for much greater strength and rigidity compared to angles or channels. This steel shape is easy to weld, cut, form and machine with the proper equipment and knowledge.
