Cold rolled coils & sheets · Size & tolerance table

Cold rolled sheet and coil tolerances (EN 10131, formerly DIN 1541)

Standard: EN 10131 formerly DIN 1541

EN 10131 gives the tolerances on dimensions and shape for cold rolled uncoated and zinc or zinc-nickel electrolytically coated low-carbon and high-yield-strength steel flat products for cold forming. It replaced DIN 1541. Two tolerance classes are given: normal, and special (S) for closer limits, which must be asked for on the order.

The values below are those of the first edition (EN 10131:1991) as carried on the old site. The current edition (EN 10131:2006) keeps the same structure but groups the steels by minimum yield strength differently; use the current edition for contract purposes.

Thickness tolerances, low-carbon steels

Thickness	Normal tolerance, width			Special tolerance (S), width
Nominal thickness mm	≤ 1200 mm	> 1200 ≤ 1500 mm	> 1500 mm	≤ 1200 mm	> 1200 ≤ 1500 mm	> 1500 mm
≥ 0.35 ≤ 0.40	± 0.04	± 0.05	–	± 0.025	± 0.035	–

For wide strip and slit wide strip the thickness tolerance may be exceeded by up to 60 % over a length of 15 m around a cold-rolling weld.

Width tolerances, sheet and wide strip

Width	Normal		Special (S)
Nominal width mm	Lower mm	Upper mm	Lower mm	Upper mm
≤ 1200	0	+ 4	0	+ 2
> 1200 ≤ 1500	0	+ 5	0	+ 2
> 1500	0	+ 6	0	+ 3

Notes

Out-of-squareness of sheet may not exceed 1 % of the actual width. Edge camber may not exceed 6 mm over 2 m (0.3 % of the length for sheets shorter than 2 m).
