Product Description

square steel tube carbon material 300mm a hollow square-shaped lightweight thin-walled Steel Pipe, also

known as steel cold-formed profiles.square steel tube carbon material 300mm It is hot-rolled or cold-rolled strip or coil as the base material

by cold bending after forming and then by high-frequency welding made of square cross-sectional

shape of the size of the steel.square steel tube carbon material 300mm Hot-rolled special thick-walled square pipe in addition to wall

thickening of the situation, the corner size and edge flatness are even more than the resistance of

cold-formed square tube level.square steel tube carbon material 300mm Good mechanical properties, weldability, cold, hot workability and square steel tube with black paint 300mm

we can supply kinds of steel pipe ,such as Seamless Steel Tube ,LASW Steel

pipe,Erw Carbon Steel Pipe,Galvanized Steel Pipe,Rectangular Pipe,Steel

Rectangular Tubing,Square steel pipe and so on . the material for pipes are

ASTM A106 GR.B,ST37-2,ST52,API 5L GR.B,Q235 and so on .

corrosion resistance are good, with good low temperature toughness.
