1-6mm Metal Steel Coil Slitting Line

Not like light gauge steel slitting machine, medium gauge and heavy gauge coil slitting line has 2 leveling units. One lays before slitting machine, and another one lays before final recoiling to ensure the high quality of slitting and recoiling and perfect flatness of the strip material.

  1-6mm Metal Steel Coil Slitting Line  

Believe Industry Company supply light gauge steel coils slitting line, medium gauge coil slitting line and heavy gauge slitting line. 1-6mm semi-automatic metal steel coil slitting line belong to the group of medium gauge slitting line.


1-6mm thick materials undergoes 2 steps of leveling/flatening to ensure the perfect flatness of the final strip coils. One leveling unit is laid before guiding and slitting, another leveling unit laid before recoiling.
