3. Main Quality Requirements
Surface processing is good, does not allow to have a black, marks, tire tracks, corrosion, pressure folds, creases, straightening roller printing, oil stain, stick injuries, scratches, metal and non metal pressed into etc. obvious defects, the strip flatness degree greater than 10I (or wave height is less than or equal to 3 mm, wavelength is preferably more than 400mm).

4. Production Control
(1) strict control of good width tolerance.
Thickness tolerance: + 0.01mm (preferably 0.005mm)
Width tolerance: + 1mm
Flatness requirements: height less than 3mm, within 1 meters of the wave number is less than 3;

(2) heating system: the furnace gas temperature 490 degrees, 33 hours of heat preservation, baked temperature 475-485;

(3) roller type: -0.02mm;

(4) emulsion index: according to the actual production conditions at the time of hot rolling;

(5) under the machine thickness: to meet the process requirements between 6.0-6.5mm, as far as possible by the lower limit control;

(6) surface control: the hot surface in a flat road, the first coiling and second coiling can have uniform white phenomenon, final coils via sub surface exposed metallic luster and color uniform, no white and aluminum adhesion phenomenon.

Surface does not allow scratches, scrapes, sand hole, and so on the depth of the defect, can with the imprint of mild steel, mild trachoma, slight pitting, the edge can be cut within the range of the weight of the edge of the skin.
