Around cold-rolled welds - the pickling welds - an increase of 20% at the most over the thickness is allowed over a length of 15 metres.

The tolerances for width comply with standard: EN 10131, 2006.

Width tolerances closer than Special tolerances (S) are possible after consultation.

Dimensions in mm:

Nominal width		Tolerances normal		Tolerances special (S)
		lower	upper	lower	upper
≥ 750	≤ 1200	0	+4	0	+2
> 1200	≤ 1500	0	+5	0	+2
> 1500	≤ 2055	0	+6	0	+3

A special width tolerance of ± 0.25 mm is available on request for widths between 750 and 2000 mm.

Out-of-squareness

The deviation does not exceed 1 % of the actual width of the sheet according to the EN 10131 standard.

Edge camber

The deviation from the edge camber does not exceed 5 mm for a length of 2 metres.

Flatness for skin-passed steel

The flatness tolerance always fulfils the EN 10131 standard.

The following applies to steel grades with R_e < 260 N/mm².

Dimensions in mm:

Tolerance	Nominal width		Nominal thickness
			< 0.7	0.7 ≤ t < 1.2	≥ 1.2
normal	≥ 750	< 1200	10	8	7
	≥ 1200	< 1500	12	10	8
	≥ 1500	≤ 2040	17	15	13
special (FS)	≥ 750	< 1200	5	4	3
	≥ 1200	< 1500	6	5	4
	≥ 1500	≤ 2055	8	7	6

For steel with Re ≥ 260 N/mm² the following applies.

Dimensions in mm:

Tolerance	Nominal width		Nominal Thickness
			< 0.7	0.7 ≤ t < 1.2	≥ 1.2
normal	≥ 750	< 1200	13	10	8
	≥ 1200	< 1500	15	13	11
	≥ 1500	≤ 2040	20	19	17

	≥ 1200	< 1500	9	8	6
	≥ 1500	≤ 2055	12	10	9

A more narrow flatness requirement is available on request.

Winding

For winding, there may be a maximum width gap of 3 mm between two consecutive windings. The total width stagger across the coil wall will not exceed 10 mm.
