Welded steel pipe, also known as welded pipe, is made of steel plate  or strip steel after crimping. The production process of welded steel pipe is simple, the production efficiency is higher, the cost is more lower, the product variety is getting richer, but the general strength is lower than seamless steel pipe.

Square rectangular pipe is a term for square and rectangular pipes, which refers to steel pipes with equal or unequal side lengths. It is rolled from strip steel through process processing. Generally, the strip steel is unpacked, flattened, curled, and welded into circular tubes, which are then rolled into square tubes and cut to the required length.
