Narrow tolerances can reduce the productivity of the profile and thus the cost. This has to be taken into consideration when designing the profile.
Alumeco is working according to the Standards of European Committee for Standardization, CEN, EN 755-9 and EN 12020-2. In this handbook, you will find an extract of these standards. Text and values are taken from there.
The standards have to be considered as guidance. In the case of profiles which, due to the complexity of their design, are difficult to manufacture and specify, then special agreements between customer and Alumeco may need to be reached.
