Notes.
a. It is allowed to be delivered in uncut state, and the allowable deviation of its width is 0~+5mm.
b. Thickness allowable difference is the thickness difference between the center of the steel plate and 15mm from the edge.
c. The longitudinal thickness difference is the difference between the maximum thickness and the minimum thickness measured along the length of any 2 m length of steel strip (parallel to the rolling direction).
d. For users with special requirements, Baosteel can supply standard +α.
