Producing method: Hot rolled or cold formed

 seamless square tube is made of seamless tube extrusion process can also be processed through 

the strip roll is made.

Usage industry: Structure pipe in constructions, making machinery and shipping building ,bridge

building  And so on 

Q345b Square Hollow Section It is a low carbon alloy steel (c <0.2%), good overall

 performance, good low temperature performance, cold stamping performance, welding

 performance and machinability. Widely used in bridges, vehicles, ships, construction, pressure

 vessels and so on. Q represents the yield of this material, followed by 345, refers to the yield

 value of this material, at 345MPa or so. And will increase with the thickness of the material to

 reduce its yield value.
