Material Protection

Surface Care

Aluminum coils must be handled with care to stay clean. Dedicated slitting lines use special systems to protect the coil surface. Operators see padded rollers and soft guides that stop scratches. Machines keep the tension even, so the coil does not slip. This helps prevent marks and dents on the product.

Manufacturers use special packaging to keep coils safe from dust and water. Barrier materials with low water vapor rates keep water out. Some lines put vapor corrosion inhibitors and desiccants inside the package. These features stop stains and rust before they start.

Tip: Storing coils inside in dry, airy places gives more protection. This easy step keeps the surface shiny and clean.

Aluminum Properties

Aluminum is soft and needs extra care. It can bend or change shape if not handled right. Dedicated slitting lines use strong packaging and careful handling to stop problems like ovalization or telescoping. These problems can cause waste and slow down work.

Operators follow strict rules when lifting and moving coils. They use the right tools and enough strapping to keep the coil’s shape. Keeping winding tension steady during slitting also helps protect the coil.

·        Material protection steps in dedicated slitting lines include:

1.         Storing coils inside to keep out moisture.
2.         Using barrier packaging with vapor corrosion inhibitors and desiccants.
3.         Using the right strapping and lifting methods.
