6.Square hollow section steel classification

We all know that there are many types of square hollow section steel . Today, the editor will provide a detailed introduction to the classification of square tubes:

Classification by process

Square hollow section steel are divided into hot-rolled seamless square tubes, cold-drawn seamless square tubes, extruded seamless square tubes, and welded square tubes according to production processes.

The welded square tube is further divided into:

(a) According to the process - Arc welding square tube, Electric resistance welding square tube (high-frequency, low-frequency), gas welding square tube, furnace welding square tube

(b) Classified by weld seam - straight seam welded square pipe, spiral welded square pipe

Classification by Material

Square pipes are divided into plain carbon steel square pipes and low alloy square pipes according to their material. Plain carbon steel is divided into Q195, Q215, Q235, SS400, 20 # steel, 45 # steel, etc; Low alloy steel is divided into Q345, 16Mn, Q390, ST52-3, etc.

Classification according to production standards

Square tubes are classified according to production standards: national standard square tubes, Japanese standard square tubes, English standard square tubes, American standard square tubes, European standard square tubes, and non-standard square tubes.
