Note:
(*) the figures do not apply to the coil ends for length L(m)=90/nominal thickness (mm)
Asymmetrical tolerances are also accepted, provided the total excursion is less than the figures of this table.
Width tolerances
Black, pickled and galvanized coils with mill edges (ref. UNI EN 10051) | |
Nominal width (mm) | Tolleranza (mm) |
L ≤ 1200 | -0 / +20 |
1200 < L ≤ 1600 | -0 / +20 |
Black and pickled strips/blanks with trimmed edges Width < 600 mm | |||||
Nominal width (mm) | Width tolerance (mm) | ||||
sp ≤ 3,0mm | 3,00 < sp ≤ 7,0mm | sp > 7,0mm | |||
L ≤ 100 | -0 / +0,3 | -0 / +0,4 | -0 / +0,5 | ||
100 < L ≤ 250 | -0 / +0,4 | -0 / +0,5 | -0 / +0,6 | ||
250 < L ≤ 400 | -0 / +0,5 | -0 / +0,6 | -0 / +0,7 | ||
400 < L < 600 | -0 / +0,6 | -0 / +0,7 | -0 / +0,8 |
Note: these are the minimum tolerances feasible; in the absence of prescriptions in the order, by default standard tolerances are inserted into the system. Other tolerances are also accepted, all negative or overlapping, provided the total excursion is not below the figures in this table.

Nominal width (mm) | Tolerance (mm) for th. ≤ 2 mm | Tolerance (mm) for th. > 2 mm | |||
600 ≤ L ≤ 1200 | -0 / +2 | -0 / +3 | |||
1200 < L ≤ 1600 | -0 / +3 | -0 / +4 |
Note: these are the minimum tolerances feasible; in the absence of prescriptions in the order, by default standard tolerances are inserted into the system. Other tolerances are also accepted, all negative or overlapping, provided the total excursion is not below the figures in this table
