Flat / Cold Rolled
Cold rolled coils or flat steel products are produced by rolling hot rolled flat steels without a heat treatment operation in a thickness range of 0.20 to 2.00mm. While the product’s physical properties are all homogeneous along the strip, surface flatness, width and thickness values have fulfilled expectations at the top level.

- Tensile test values apply to "transverse" test pieces
- The value of r90 only apply to products of thickness d ≥ 0.5 mm.
- For design purposes, the lower limit of Re may be assumed to be 140 N/mm² (14.3 kg/mm²)
- Guarantee periods of absence of stretcher strains marks and mechanical properties are 6 months. The period begin on the date on which products are made available.
