Black Steel Hot Dip Galvanized Coating Square Tube Rectangular Hollow Tubular Steel Pipe
Galvanized square steel pipe, rectangular steel pipe, steel hollow section, divided according to the shape of the section, is a name for square pipe and rectangular pipe. It is made of strip steel that has been processed and rolled. Generally, the strip is unpacked, flattened, coiled, welded to form a round tube, and then rolled into a square tube from the round tube and then cut to the required length. Square rectangular tube is also called cold-formed hollow section steel, referred to as square tube and rectangular tube.
