Dimensional tolerances

Nominal thickness(mm)	Thickness tolerance(mm)	Transverse thickness tolerance(mm)	Longitudinal thickness tolerance(mm)	Width tolerance(mm)	Flatness (%)	Camber 2m(mm)
0.15	+0.008 -0.015	≤0.010	≤0.012	0~+0.5	≤1.0	≤0.8

0.20
0.23	+0.010 -0.020
0.27		≤0.012
0.30	+0.010 -0.025

Note:

1. Traverse thickness deviation refers to the thickness difference between the sheet center and 15mm from the edge.

2. The longitudinal thickness difference is the difference of the measured maximum thickness and the minimum thickness in the longitudinal direction at an arbitrary 2m length of steel on a arbitrary coil.

3. Please consult us if you have any special dimensional requirements.
