Expert tip

The tolerances for thickness and flatness are very wide in rolled plates. For example, a 20 mm thick plate has a thickness tolerance of ± 0.7 mm. The flatness is specified as a percentage and is calculated longitudinally (always in the rolling direction!) and in width (always transverse to the rolling direction!). A 20 mm thick slab in format 1,520 x 3,020 mm may vary by 0.2% = 6.04 mm and 6.08 mm in width from the flatness.

In comparison, G.AL® C250 in 20 mm thickness: thickness tolerance: ± 0.1 mm, flatness: 0.13 mm.
