Tolerances for aluminium profiles (DIN EN 12020-2 : 2001-07)*


Cross-section dimensions
General information


The limit deviations of the following dimensions are specified in the corresponding tables 1 and 2.

– A:     Wall thicknesses, except for those which enclose the hollow spaces in hollow profiles

– B:     Wall thicknesses which enclose the hollow spaces in hollow profiles, except for wall thicknesses between two hollow spaces

– H:     All dimensions except for wall thickness

– CD:  Circumscribing circle

Limit deviations for dimensions other than wall thickness

Table 1 – Limit deviations for cross-section dimensions


Limit deviations of wall thicknesses of solid and hollow profile

Table 2 – Limit deviations of the wall thicknesses

* Important: We assume no liability for cited standards!

All dimensions in mm.
