Plain carbon steel square pipe is a square equilateral steel pipe. Implementation of the national standard GBT 6728-2002 cold-formed hollow section steel for structure, size, shape, weight and allowable deviation processing and production, is rolled from Q345B strip steel. The low-alloy square tube is made of low-alloy material (Q345B), which is very different from the ordinary square tube in raw material (Q195, Q215, Q235). The low-alloy strip steel (16Mn) is unpacked , flattened, crimped, welded to form a round tube, and then rolled into a square tube from the round tube and then cut into the required length. The usual length is 6 meters, 12 meters or other fixed lengths.

Material selection—material inspection—material warehousing—extrusion molding—annealing—straightening—heat treatment—mechanical performance inspection—chemical analysis—tensile test—inspection—cutting to length—honing—end processing—finished product warehousing—finished product reprocessing Inspection - finished product delivery
