Cold-rolled steel is manufactured by a process wherein sheet metal is placed between a pair of rollers and then compressed and squeezed to produce the required thickness. The resulting steel product thus has a good surface finish and excellent mechanical properties and is widely used as a basic material for automobiles, consumer electronic products, furniture, construction materials and office supplies. After compressing and squeezing, cold-rolled steel is subjected to various processes depending on its utility, such as zinc or electric coating and color coating which applies paints on the surface of the steel. Cold-rolled steel is categorized roughly into coils (long, uncut steel) and sheets that are cut and then folded into shape in multiple layers.
Product Type
· Regular sheet/sheet with BA (bright annealing): A high value product with good surface finishing characteristics and workability; widely used for automobiles, consumer electronics products, mechanical parts, accessories, stationery, etc.
· Hi-Carbon: A high-strength product used for automotive parts, knives, tape measures, etc.
· Mill Clean (off-gauge cold rolled steel): Steel sheets with thickness of 2.3 mm or above
· Sunboss (Cold-rolled steel with one of its sides treated with sheet metal embossing): Gives a soft feel when touched and offers anti-fingerprint properties; used effectively for home electronics products and furniture that come into frequent contact with hand and fingerprint
Chassis, CRT television sets and computer monitors, refrigerator and air conditioner parts, luxury mirrors, etc.
