Tolerances

SSAB Weathering is delivered with SSAB Weathering tolerances, with improved guarantees compared to corresponding EN standards. More details are available at SSAB.com

Thickness

Strip:SSAB Weathering thickness tolerances correspond to 2/3 of EN 10051:2010 as default value. After special agreement, tolerances down to 1/2 of EN 10051:2010 can be delivered for certain products and dimensions.

Plate:COR-TEN A is delivered with tolerances that correspond to ¾ of EN 10 029:2011 as default value.

Length and Width

Strip:SSAB Weathering tolerances for width and length are according to SSAB standard and offer narrower width and length tolerances compared to EN 10051:2010.

For coil and sheet with mill edge, the width tolerances are corresponding to -0/+20 mm.

For coil and sheet with cut edge, the width tolerances are corresponding to -0/+2 mm.

After special agreement, tighter tolerances can be delivered for certain products and dimensions.

Length tolerances only apply for cut to length sheets.

Plate: Width tolerances are -0/+4-10mm depending on the thickness. Length tolerances are -0/+15-25mm depending on length.

Shape

Strip: SSAB Weathering is delivered with shape tolerances according to EN 10051:2010. Narrower tolerances according to the SSAB standard are available on request.

Plate:According to EN 10 029:2011.

Flatness

Strip:SSAB Weathering tolerances correspond to SSAB Flatness Guarantees Class A.

SSAB Weathering tolerances guarantee a maximum flatness deviation of 3 mm/m in addition to the EN 10051:2010 flatness requirements.

Delivery Conditions

Coils, slit coils and cut to length: Controled rolled or thermomechanical rolled.

Heavy plate: Hot-rolled, normalised rolled or normalised in furnace.

Inspection documents

The inspection document shall be specified at the time of order. The European types of inspection documents are defined in the EN 10204:2004 standard.
