How to use our deflection calculator

Learn more about how to select the most suitable profiles for your weight and cost-optimized constructions.
Based on our high quality aluminium profiles and our software to calculate the accurate deflection you can ensure that maximum loading must not permanently deform the profile while.

The important parameters to calculate the aluminum profile deflection are:
     length
     dead load
     loading - also take unexpected loading into account!

Go to Products - Profiles and Accessories - Profiles and select a product.

In the last tab of the product detail page you will find the Deflection Calculator.

Enter the length of the profile.

Now enter the intended operation force and click on the "calculate" button.

Check the profile deflection based on your selected profile, load scenario and profile length.

Load scenario 1 is a beam that is fixed at one end (e.g. open cantilever rack)
This load scenario is the most unfavourable of the three variants due to the one-sided fixing, which produces a large lever arm.





Load scenario 2 is a beam in bending that is not fixed in place at either end.
Of course, this is not a realistic design, as the horizontal profile in the load scenario is not screw-attached to the vertical profiles and is merely resting on the corner points. However, load scenario 2 can be used as a basis for calculations in order to incorporate an additional safety factor when calculating deflection (without fixed-end moment).

Load scenario 3 is a beam in bending that is firmly fixed at both ends.
This load scenario exhibits the least deflection of all three variants when applying the same force and represents an ideal installation scenario. This ideal model – a beam in bending that is firmly fixed at both ends – cannot be implemented in a frame construction under real-life conditions.

We recommend using load scenario 2 as a basis for calculating your constructions that delivers an adequate safety factor. Of course, in reality – unlike in load scenario 2, where the beam in bending is not fixed at either end – the profiles in your construction frame will be screw-attached to vertical profiles.
Consequently, the real and achievable loading value for the profiles will lie somewhere between those of load scenarios 2 and 3.
