Product Description

Black square steel tube ASTM A53 Grb


black square steel tube ASTM A53 Grb 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

 corrosion resistance are good, with good low temperature toughness.
