They are distinguished for:
- Excellent bearing capacity as a structural component
- Excellent reaction to fire, category A1
- Excellent weather and corrosion resistance
- Easy and fast standard mounting
- Fixed dimensions, depending on the project requirements
- Open section structural steel profiles
The design and production of the individual components shall be subject to all relevant checks for the least favorable load combinations. The assembly of the components must be done by qualified personnel at the project site.
Components / Items
Open sections type C 140-20, as main components
The main components of the structure system are C140-20-type open sections, which are used as beams and poles. Alternatively, type M (or Sigma) open sections may be used, where the strength requirements are increased.
Open section type C40x20 and C40x40, as intermediate components
The intermediate components of the complex structure are type C40x20 and C40x40 open sections, which used as purlins and gable bracings. These particularly open sections allow the use of T-Bolt for anchoring the photovoltaic panels.
The assembled structure could be mounted to the concrete base with bolts, anchors and L type angles 150x100x3mm.
Bolts and Screws
In general, welding in thin wall sections is not applicable. All connections between the cross-sections are mechanical (bolts and screws). M12 / 8.8 and M5.5 / 8.8 bolts and M12 / 8.8 concrete anchors are used for the connections between the various sections.
For the substructure is proposed a concrete footing, which offers greater stability to the construction and reduces the movements due to the wind. The reinforced concrete footing that is used should be of concrete quality C16 / 20 and steel reinforcements grade B500.
