Quality of JIS G 3141
- commercial quality is used for simple bending, forming or drawing, and has a wide range of uses for automotive, home appliances, building and civil works and base metals for various kinds of prepainted steel products.
- drawing quality is used for better than the commercial quality, it's high formability is used for automotive panels, audio-visual equipment and other heating apparatuses.
- deep drawing quality is used for the parts of complicated and severe forming products, mainly for the automotive front panels and rear fenders.

D (Dull Finish) - matt finish produced with a roll roughened its surface mechanically or chemically
B (Bright Finish) - smooth finish produced with a roll finish its surface smoothly
Special care is given to prevent abrasion, rust and scratch during transportation and shipment, the procedures are illustrated as follows.
Unit weight is usually 2-5mt for sheet, 4-20mt for coils upon to the request.
