| Commercial: Sheet of this quality is for simple bending or moderate forming.   Commercial steel sheet can be bent flat upon itself in any direction at room   temperature. It has a wide variety of uses, including automotive panels,   electrical home appliances, drums, pipes, farm implements, office supplies,   building and civil work materials, and as base metal for various   coatings.Bright finish: Bright finish presents high-quality   roughness that is optimal for decorative purposes. The sheet surface is rolled   with fine polished rolls.Drawing: Sheet of this quality has a greater degree of ductility   and is more consistent in performance than commercial steel because of higher   standards in production, selection and melting of the steel. It is suitable for   automotive panels, audio-visual equipment, and heating apparatus.
 Deep   drawing: Sheet of this designation should be used when drawing steel will not   provide a sufficient degree of ductility for fabrication of parts with stringent   drawing requirements, or applications that require the sheet be free from aging.   This quality is produced through special steelmaking and finishing practices. It   is suitable for automotive front panels and rear fenders.
 Stabilized deep   drawing: Stabilized deep drawing quality products boast the highest quality in   terms of workability. It is suitable for automotive parts that require   complicated treatment such as front fenders or wire. As a non-aging deep drawing   sheet made with Al-killed, quality is guaranteed against extreme stretching or   straining.
 Surface finish: The surface finish of cold-rolled steel sheet is   either dull or bright.
 Dull finish: Dull finish, which is attained by   attaching numerous fine grains onto the steel surface, is often called   ’pear-skin finish’ or ’egg-shell texture’. The grains are made by steel grit   blasted roll. The dull finish is useful in drawing because lubricant oil can be   evenly spread over the entire surface, thereby reducing the possibility of   friction.The fine grains also help boost paint adherence and extend the steel   life span of the steel.
