PRODUCT DESCRIPTION

Rectangular tubes, rectangular tubes, square tubes, welded square tube, because it has a lot of kinds of material of material can make the tube body, usually square tube is formed after unpacking, kaiping, bending strip welding pipe, again by the mechanism of rolling into a square tube.

Hot-dip galvanized square tube: It is a square tube made by welding a steel plate or steel strip after being curled and formed. On the basis of this square tube, the square tube is placed in a hot-dip galvanizing pool and undergoes a series of chemical reactions. A square tube formed. The production process of hot-dip galvanized square tubes is relatively simple, the production efficiency is very high, and there are many varieties and specifications. This kind of square tubes requires very little equipment and funds, and is suitable for the production of small galvanized square tube manufacturers. However, in terms of strength, the strength of this steel pipe is far lower than that of seamless square pipes.

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.
