    Introduction of the square & rectangular tube mill
    Square & rectangular tube mill is the equipment for closed profile steel production with sectional mould, fast roller changing with no spindle removal, load of the machine is low, which may not only decrease the roller cost but also save the time. Every four angles of the square and rectangular tubes has high intensity with no variation. The mill is composed of uncoiler, levelling machine, butt welder, storing device, high frequency equipment,etc.
    material: carbon steel and low alloy steel
