Our Metal Steel Aluminum PPGI Slitting & Cut-to-Length Line is engineered to deliver stable performance, precise cutting, and flexible configuration for a wide range of coil materials and production requirements.

This production line integrates uncoiling, leveling, slitting, cutting, conveying, stacking, and recoiling into one continuous and automated system, making it ideal for steel service centers, roofing sheet factories, and metal processing plants.

Complete Production Line Configuration

Main Components Overview

Working Process Flow

Uncoiling → Feeding → Precision Leveling → Slitting (Scrap Rewinding) → Cutting to Length (Optional) → Conveyor Transfer → Automatic Stacking → Tension Control → Recoiling

This smooth and logical workflow ensures consistent strip quality while minimizing manual intervention and material waste.
