C. Characteristics :

Material	Features and Applications
General	The main applications are home appliances, painted steel sheet materials, pipes, etc. and are used in products that are subject to flat sheets or roll formatting. It is also used for building materials and furniture.
For bending	It is used as internal parts of home electronics, lighting devices, cars, building materials, and furniture and for applications required for substance guarantee by bending processing.
For deep processing	It is used for applications that require excellent processability and age guarantee. It is mainly used for air conditioning panels, vacuum covers, and auto parts.
For structural use	It is used mostly for building materials and for products that require high strength, such as the deck plate, dust Purlin, and panels. It is difficult to secure processability, so it cannot be used when drawing is required.
For processing	It is used for applications that require drawing during processing and is mainly used for home appliances and automobile parts.
