Cold drawn steel pipe is a type of steel pipe, which is classified according to different production processes and is different from hot-rolled (expanded) pipes. It is formed through multiple passes of cold drawing during the process of expanding the blank or raw material tube, usually carried out on a single chain or double chain cold drawing machine of 0.5-100T.

Galvanized square pipe is a kind of hollow square section steel pipe with hot rolled or cold-rolled galvanized strip or galvanized coil as billet after cold bending processing and forming and then made by high-frequency welding, or the cold-formed hollow steel pipe prepared in advance and then processed by hot dip galvanizing.

Stainless steel square tube is a hollow strip of steel called a square tube because its cross-section is square. A large number of pipelines are used for conveying fluids, such as petroleum, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, they are lighter in weight, so they are also widely used in the manufacturing of mechanical parts and engineering structures.
