The versatility of aluminium cold rolled coils makes them indispensable across a variety of sectors. Below are some common applications:
Bus cabins and bodies
Construction Industry:
False ceilings and panelling (plain or colour-coated coils)
Electrical Industry:
Cold Rolling: This involves passing the aluminum through a series of rollers at room temperature. Each pass reduces the thickness and enhances the mechanical properties, like tensile strength and hardness.
The process starts with high-quality aluminum ingots that are precisely prepared for rolling. These ingots are cleaned and prepped to ensure a smooth transition into the rolling process.
The cleaned ingot is passed through a series of rollers, each making incremental reductions in thickness. This process is closely monitored to ensure precision and consistency across the entire coil.
