Square rectangular pipe is a name for square pipe and rectangular pipe, that is, steel pipes with equal and unequal side lengths.

 

It is made of strip steel by processing and rolling. Generally, the strip is unpacked, flat, crimped, welded to form a round tube, which is then rolled into a square tube and cut to the required length.

The usual delivery length of rectangular tubes is 4000mm-12000mm, with 6000mm and 12000mm being the majority.

 

 

Application: Widely used in machinery manufacturing, construction industry, metallurgical industry, agricultural vehicles, agricultural greenhouses, automobile industry, railway, highway guardrail, container skeleton, furniture, decoration and steel structure fields.

 

Square pipe according to the production process: hot rolled seamless square pipe, cold drawn seamless square pipe, extrusion seamless square pipe, welded square pipe
