Published on: 30. June 2025

Tolerances for aluminum profiles define the maximum permissible deviations in shape and dimensions that may occur during production without impairing the functionality or quality of the components.

Standards and sizes

  • DIN EN 12020-2: Standard for extrusion profile tolerances.
  • DIN 16901: Definition of tolerances for sheet metal components.

Meaning

  • Ensuring the accuracy of fit and function of components.
  • Increasing interchangeability and improving production processes.
