What Precautions Should Be Taken During the Processing of Galvalume Steel Coils?

1. Cutting and Stamping: Prioritize cold working methods and avoid high-temperature cutting (e.g., flame cutting) to prevent damage to the surface coating. Use sharp dies for stamping to minimize coating abrasion and peeling, and maintain the dies regularly.
2. Bending and Forming: Do not use an excessively small bending radius, as this may cause the coating to crack due to stretching. If the base material is exposed at the edges after forming, conduct rust-proofing treatment in a timely manner (e.g., touch-up with zinc-rich paint).
3. Handling and Storage: Avoid collision and friction on the surface during handling to prevent coating scratches. Store the coils in a dry and well-ventilated area, away from corrosive substances such as acids and alkalis, and place them on sleepers to keep them off the ground for moisture protection.
