Steel Coil Slitting Machine Product Details

1. Equipment Overview

The Steel Coil Slitting Machine is a professional industrial equipment designed for longitudinally slitting metal coils (e.g., hot-rolled steel, cold-rolled steel, stainless steel) into multiple narrow strips. Widely used in steel processing, automotive manufacturing, and home appliance production, it ensures precise dimensions and smooth edges with high-precision blades and automated control systems.
