Cold Rolled Continuous Annealed Steel Coils and Sheets (CRCA) have fine surface and excellent workability. They are used for various purposes including automobiles, home appliances, furniture, office equipments, Drum, Barrels industrial machines and construction material.
Applications
Used for General Purposes in Manufacturing such as:
- Refrigerator
- Air conditioners
- Washing Machines
- Drums / Tubes
- Furniture
- Control Panels
- Decorative lamps
Structural Steel does not need drawability but requires high strength like
- Steel Furniture – Desk, lockers, almirahs, racks, light weight chairs etc
- Structure – Roofing, side walls, partitions, panels, valley gutters, louvers, false ceilings, partition walls and ducks, rolling shutters, highway bumpers, slotted angles and paint coated products etc
Used where high strength with good formability is required
- Automobile Seats, Parking brackets
- Center floors and Brackets, Frames
- Fender and Hood
Used where deep drawing quality is required
- Automobiles components & Body Panels
- Air and Oil Filters
- Fuel Tanks
- Components for Building
