Raised flat-roof frames with the S:FLEX Delta triangle
All benefits of our systems with the S:FLEX Delta triangle at a glance:
- Variable use of framed and frameless PV modules on flat roofs of old and new buildings
- Installation on ballast stones, hanger bolts or trapezoidal sheet metal rails is possible; special solutions on request
- Horizontal or vertical module installation
- Delta triangles are available with tilt angles from 5° to 45° (in 5° increments)
- Minimised storage and transport costs: The triangles are delivered pre-installed but collapsed. Transport and storage of up to 252 pcs. per 130x80 cm (approx.) pallet
- Quick installation of the substructure thanks to a very high degree of pre-assembly, our latest one-click technology and a detailed installation recommendation
- Maximum flexibility during installation due to variably adjustable module clamps and end clamps for modules with a frame height of 30–50 mm; certified laminate clamps are available for frameless modules
- Excellent adaptability to ensure a flat PV array – even on uneven roof surfaces thanks to height-adjustable mounting rails
- Long service life, complete recyclability and corrosion resistance thanks to 100% aluminium and stainless steel components with a 10-year warranty
- System load capacity in accordance with DIN EN 1991-1-4:2010-12 (wind loads) and DIN EN 1991-1-3:2010-12 (snow loads), on request testable structural calculations for maximum safety
- We will gladly create the structural design for our customer's projects if required – the documentation we provide includes the structural analysis and the ballast plan
Components
S:FLEX Delta triangle
Our base triangles for flat-roof elevation are pre-assembled for quick installation.
Mounting rails
S:FLEX mounting rails are used as floor rails to mount the base triangles or as module carrier rails for vertical mounting. The hollow chamber rails are structurally optimised and available in different cross-sections and lengths.
Rail connectors
To ensure structurally identical properties in the area of the rails and the connections.
Trapezoidal sheet metal rails
Our trapezoidal sheet metal rails allow direct installation on trapezoidal sheet metal roofing. In addition, they can be used as floor rails to support high quantities of ballast.
End and mid clamps
S:FLEX module clamps have an extremely wide clamping area and are therefore suitable for all standard modules and frame heights of 30-50 mm. High torsion resistance and our latest, ultra-smooth one-click technology make installation a snap.

The easiest way to use flat roofs for photovoltaic systems
The S:FLEX roof frame with ballast is the simple and proven solution for non-penetrative, green-roof-compatible flat-roof installations. A number of attachment and ballast options are available depending on the planned system and the conditions on site.
On flat roofs without roof structures and in regions with high wind loads, we recommend installing Delta triangles for ballasting. In this case, a particularly high quantity of ballast can be flexibly distributed over the rails.
For roofs with a lower load-bearing capacity and roof superstructures on which longer rails cannot easily be laid, the triangles are attached directly to ballast blocks/stone slabs.
Installation of the substructure with S:FLEX Delta triangles with our universal one-click installation principle and ballast – such as weighting stones, gravel or green-roof granules – ensures absolute roof-tightness and easy dismantling. It also offers all the benefits of a raised-panel solution. As well as straightforward maintenance and easy accessibility of both the roof surface and the PV system, high system efficiencies are also achieved thanks to optimal rear ventilation.
