General Product Description
With its anti-corrosive properties, COR-TEN® minimizes the need for maintenance and corrosion-prevention treatment, contributing significantly to low maintenance costs throughout the product lifecycle. In addition to low maintenance costs, the reduced need for corrosion prevention means less use of paint and solvents, making COR-TEN® an environmental friendly choice of steel.
Typical applications are structural components for buildings, transmission poles, bridges and many others.

Tolerances
COR-TEN® B-D is delivered with SSAB Weathering tolerances, with improved guarantees compared to corresponding EN standards. More details are available at SSAB.com
Thickness
Hot rolled Strip: Thickness tolerances correspond to ⅔ of EN 10051 as default value. After special agreement, tolerances down to ½ of EN 10051 can be delivered for certain products and dimensions.
Plate: Thickness tolerances that correspond to ¾ of EN 10029 as default value.
Length and Width
Hot rolled Strip: Width and length tolerances according to SSAB standard which offer narrower tolerances compared to EN 10051.
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.
Length tolerances only apply for cut to length sheets.
Plate: Width tolerance is -0/+4-10mm depending on the thickness. Length tolerances are -0/+15-75mm depending on length.
Shape
Hot rolled strip: According to EN 10051. Narrower tolerances are available on request.
Hot rolled plate: According to EN 10029
Flatness
Strip:
Flatness tolerances guarantee a maximum flatness deviation of 3 mm/m in addition to the EN 10051 flatness requirements.
Flatness guarantees only apply for cut to length sheets.
Plate: Max flatness deviation 6 mm/m.
Surface Properties
According to EN 10163-2 Class A, Subclass 3.
Delivery Conditions
Coils, slit coils and cut to length: Controlled rolled or thermomechanically rolled.
Plate: Hot-rolled, normalized rolled or normalized 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 standard.
