Flat / Hot Rolled

Flat steel products are obtained by heating semi-finished products with a rectangular cross-section (slab), which are produced by the continuous casting method, to a specific temperature and then rolling them, with thicknesses ranging from 1.40 to 25.40 mm and widths ranging from 700 to 2025 mm, produceed as coil or by cutting/slit-coiling flat steel products from coils.

  1. Tensile test values apply to "transverse" test pieces
  2. Impact test is not carried out for thickness thinner than 6 mm.
  3. Produced by normalizing or rolling equivalent to normalizing, and mechanical values after normalizing are guaranteed.

Flat / Plate

Heavy plate products are obtained by rolling semi-finished products with a rectangular cross-section (slab) produced by the continuous casting method to a specific temperature, with thicknesses ranging from 6.00 to 200.00 mm and widths ranging from 1000 to 3600 mm.
