Galvanized Steel Pipe 50x50 60x60 80x80 Gi Steel Square And Rectangular Tube
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
Structural tube is often referred to as hollow structural sections or HSS. Structural Tubing, especially rectangular sections, are commonly used in welded steel frames where members experience loading in multiple directions.
Structural Applications Rectangular Tube is a hollow steel bar made of mild steel. It is hot-rolled and welded into a rectangular shape. Rectangular tubes are typically stocked in 6 metre lengths. Tubes are sized by their wall thickness and outside diameter.
The use of the rectangular tube: a large number of pipes used to transport fluids, such as petroleum, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts. And engineering structure.
