Process and Feature

High-frequency welded square tube (mainstream): Hot-rolled/cold-rolled steel strip → cold bending → high-frequency resistance welding → cut to length; high weld quality, controllable cost
Seamless square tube: used in a few high-end applications, cold-drawn/extruded from round seamless tubes, no weld seams, better pressure resistance
