Note:
1. For product thickness ≤0.5mm, the allwable thickness deviation is ±0.01mmbigger than the value in the above table; For product thickness >0.5mm, the allwable thickness deviation is ±0.02mmbigger than the value in the above table.2. We can provide customized steel strip according to customers' needs (the deviation value should not exceed the range in the above table).
