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.

303 stainless steel is an austenitic acid stainless steel containing sulfur and selenium that is easy-cutting and wear-resistant. It is used in situations where easy cutting and high surface finish are required.

302 stainless steel is an austenitic stainless steel that has 18% chromium and 8% nickel. Its chemical composition relies heavily on reasonable alloy design to achieve a series of excellent properties.

202 stainless steel is a typical representation of the 200 series of stainless steel, which is a stainless steel featuring low nickel and high manganese content. The nickel content is relatively low as it is a stainless steel developed to save nickel.

201 stainless steel generally refers to 201 stainless steel and acid resistant steel. 201 stainless steel refers to the steel that is resistant to the corrosion of weak media such as atmosphere, steam and water, while acid resistant steel refers to the steel that is resistant to the corrosion of chemical corrosive media such as acid, alkali and salt.

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.
