We offer customized slitting lines for every kind of metal strip

We offer customized slitting lines for every kind of metal strip and in all required dimensions. 

Slitting Line , called slitting machine or longitudinal cutting line, is used to uncoiling, slitting, recoiling the steel rolls into a number of narrow strips by passing the strip between circular cutters or blades. It can be applied to process the cold or hot rolled steel coil, Silicon steel coils, tinplate coils, Stainless steel and color coated steels.

Zhongheng provides customized slitting line solutions for all dimensions, from hot-rolled strip to thinnest, cold-rolled strip, from aluminum to stainless steel, in strip widths from 650 to 2,100 mm and strip thicknesses from 0.1 to 5 mm. Advanced and pioneering technologies are specially matched to the requirements of our customers. 

The high degree of automation in these slitting lines enables economical production, also of smaller lots, to reduce set-up times and to interface with coil packing and logistics.
