Product Description

Product Description

Carbon steel welded square Rectangular tube is a square tube made by welding steel plates or strip steel after curling and forming. Its production process is simple, production efficiency is high, there are many varieties and specifications, and equipment investment is low. However, its strength is generally lower than that of seamless square tube. The commonly used materials for carbon steel welded square tubes include Q235A, Q235C, Q235B, 16Mn, 20 #, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc
