Tensioned cap with central column
These are covers with a central column and a sheet that is welded to shape and then tensioned in place. No use is made of supporting beams here. Our Genatex 850 sheet from which the covers are manufactured is a foil that is fire resistant, sun resistant, UV resistant and reinforced. 
 
How does Genap go about its work?
It all begins with a design. The following design aspects are all taken into account during a comprehensive inventory of the silo or warehouse: application, material, site, new or existing, dimensions, special constructions, customer wishes such as colour, fire class, national and local requirements, explosion pressure if the roof has to collapse or shoot loose, increased or reduced pressure if the silo has forced ventilation, layout of stirrers, mixers, aerators and similar in the silo, etc.
 

All points from the inventory are included in one design.

These working drawings are used to prepare templates, item lists, specifications, work and assembly instructions. When the design is ready this is sent to the customer for approval.
 
After approval and issuing of the order a start can be made with the realisation of the cover. The foil templates are first cut on our high frequency CNC welding machine and welded in the form of the cap. The cap construction is then transported to its destination.
 
The tensioned cap construction is fitted and finally fixed to the silo. Separate parts, such as the crown and manholes, are welded to the silo cap. Finally, the silo cap is tensioned using ratchets.
