Substructure Solutions

The basis for a perfect building envelope – maximum flexibility

The substructure is the link between the outside skin and the primary supporting construction. It supports the shape of the building. There are many requirements: running parallel, oblique, curved, twisted and bent around 2 axes - and compensation of tolerances. These requirements demand a well thought through and cost-effective substructure, preferably heat bridge-free.

The patented BEMO-FLEX substructures ensure a precise fit and high-quality execution of metal coverings, even on complex building shapes and for the high construction tolerances common when renovating old buildings. 3D pre-planning - often based on a 3D scan of the actual building - makes accurate pre-planning possible as well as cost-effective pre-assembly in the workshop. 


Eminently suitable for cylindrical building shapes or those curved around 2 axes. 


The standardised system is always composed of the same components and varies between round and square pipes and different holders, depending on the configuration. The substructure can be fastened to a wide variety of bases and offers tolerance compensation of +/- 45mm.

BEMO-DOME is primarily used for:

  • façades in sports stadiums 
  • silos
  • oval towers (e.g. digester towers) 
  • or at the transition points between roof and façade

In order to obtain a perfect surface on the metal profiles, we recommend performing a 3D scan to record on-site measurements and using BEMO 3D execution planning. This will give you a grid plan with the recommended mounting points with their positions and distance from the supporting structure.

The system is characterised by good load bearing capacity, perfect tolerance compensation and simple on-site assembly. 


BEMO-FLEX is a segmented substructure. The system is extremely easy to assemble. FLEX allows you to design a 3D outer layer in easy work steps while compensating for all construction tolerances. 

The lower U profiles of the FLEX SYSTEM are mounted in accordance with structural requirements. The installation position can then be recorded in a 3D scan. From this we derive the required position and height of each BEMO holder. The upper U-shaped rails are pre-assembled with the positioning brackets in the workshop and then screwed to the lower U-shaped rail in a second work step.

The system is characterised by good bearing capacity, high compensation of tolerances and very cost-effective planning and assembly.
