Rolling Processes

Rolling Processes

Hot Rolling

Hot rolling is a process where aluminum billets and ingots are heated and passed through rollers to reduce their thickness and create sheets, plates, and structural shapes. This process enhances the material’s mechanical properties and is essential in producing components for the construction and automotive industries.

Flat Rolling

Flat rolling involves passing aluminum billets and ingots through a series of rollers to produce strip metal and sheet metal. This process is crucial in creating thin, flat products used in packaging, construction, and manufacturing.

Profile Rolling

Profile rolling shapes aluminum into desired profiles by passing billets through specially designed rollers. This method is used to create components with complex cross-sectional shapes, such as structural components, frames, and rails.
