 Roof hook with mounting rail

Versatile, safe, durable

The majority of roofs on German houses consist of bricks (roof tiles, pantiles, interlocking clay roof tiles, plain tiles, slate). The robust sloping-roof frame from S:FLEX represents the ideal solution for reliable anchoring of solar panels. It is stable and storm-proof, weatherproof and durable, yet in harmony with the architecture, not least thanks to details such as black anodised components and end caps for the rails.

 

S:FLEX mounting systems for trapezoidal and corrugated sheet metal roofs and roofing sheets

 

 

Fast installation with minimal invasive procedures
On corrugated and trapezoidal sheet metal roofing and roofing sheets, installing photovoltaic systems on the S:FLEX sloping-roof frame not only safely anchors the system, it also ensures optimum protection of the roof membrane, flexible configuration options and maximum cost efficiency.

Thanks to our wide range of different systems, we have the right installation option for almost every pitched roof as well as for slightly inclined roofs:

The low-ballast and non-penetrative system for a wide variety of roof shapes

PV mounting solution for roofs with foil or bitumen roofing and sandwich roofsThe Flat Direct from S:FLEX is an innovative PV mounting solution for roofs with foil or bitumen roofing as well as sandwich roofs. This aerodynamic system is thus particularly suitable for industrial roofs with low load-bearing capacities.

The S:FLEX Flat Direct can be used on a variety of roof shapes with a maximum pitch of 30° – saddle, single-pitch or butterfly roofs, one-sided or double-sided, with framed modules installed vertically or horizontally.

Pre-glued foam pads with a high coefficient of friction and optimum material compatibility under the aluminium floor rails ensure a secure fit with minimal ballast, while the system design includes wide gaps between the modules to ensure optimal rear ventilation and create a suction effect in the direction of the roof. Depending on the roof shape, special ridge angle connectors, counterweights or mechanical couplings ensure even greater safety when anchoring. Any necessary ballast stones are clamped to the floor rails so that they cannot slip.

Like all S:FLEX mounting systems, the Flat Direct also allows quick installation thanks to a high degree of pre-assembly and our proven modular system with pre-assembled modular rails, mid and end clamps for all frame heights and our user-friendly clickable technology.

 

Installation with the S:FLEX standing seam clamp directly onto the roof – without penetration

The advantages of the S:FLEX standing seam clamp at a glance:

  • Direct attachment of the modules to the standing seam with the S:FLEX standing seam clamp and clickable module clamps
  • Installation via cross-adapter connection also possible
  • No additional load on the roof membrane due to thermal expansion with direct mounting
  • No roof penetration –- no leaks
  • Wide clamp design ensures the load is distributed across the surface of the seam
  • Low logistics costs due to fewer components and compact designs with no long articles
  • Made of weather-resistant aluminium and stainless steel
  • We will gladly create the structural design for our customer's projects if required – the documentation we provide includes the structural analysis as well as the installation plan for all components

 

 

 

The S:FLEX standing seam clamp is the simple yet economical solution for attachment of PV modules to standing seam metal roofs.

Framed modules can be quickly, safely and cost-effectively installed directly on the roof membrane with our standing seam clamp – with our proven one-click technology, without roof penetration and with minimal transport costs and storage space requirements.

On roofing that does not permit direct module installation, the standing seam clamp can also be used in combination with S:FLEX rails and cross adapters.
