Notes:
a. Delivery of untrimmed products is allowable, with a permissible width deviation ranging from 0 to +5mm.
b. The allowable thickness difference refers to the thickness difference between the middle of the steel sheet and the part that is 15mm away from the edge.
c. The longitudinal thickness difference refers to the difference between the maximum thickness value and the minimum thickness value that are measured in the lengthwise direction (parallel to the rolling direction of any steel strip that is 2 meters long.
d. As for users with special requirements, Baosteel can deliver products according to the standard +α.
