Steel Coil Edge Protector Ring Making Machine
ID & OD Metal Edge Protection Forming Line
Steel coils require reliable protection during transportation and storage to prevent damage at their inner and outer edges. Our Steel Coil Edge Protector Ring Making Machine is designed to produce both Inner Diameter (ID) Protector Rings and Outer Diameter (OD) Protector Rings, ensuring the coil edges remain safe from deformation, friction, or collision.
This production line integrates uncoiling, punching, bending, roll forming, rib pressing, and hydraulic cutting in a continuous process. It guarantees stable performance, consistent forming accuracy, and high production efficiency for coil packaging manufacturers and steel processing centers.
