Altrex 
As an aluminium specialist, Altrex has designed a unique aluminium roof beams system. This roof beam is made almost 100% out of aluminium.
The advantages of this roof beam are:
- Low weight per component because of aluminium parts
- Assembled from just a few different components
- Easy to transport: every component fits in a standard (passenger) lift
- Assembly without tools
- Ergonomic shaped counterweights
- Patented integrated shock absorber
- Various options for different parapet heights (high and low versions)
- CE-approved (as part of a complete system)
- Variable distance between front and rear support (from 4.5 to 5.5 meter)
- Outreach (possible from 0.9 to 2.2 meter)
- Optional: extra long part for longer outreach and shorter exterior beam for short wheel base
