Stable, bolted, durable mounting systems


Installation with hanger bolt and bracket

The advantages of installation with hanger bolts/solar fasteners:

  • Direct installation on the roof substructure means there is no load on the roofing
  • Height-adjustable brackets enable level module installation
  • The roof membrane is sealed by means of precisely fitting calottes or EPDM gaskets
  • Good rear ventilation
  • 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



Our solid sloping-roof frame

Corrugated fibre cement installation with hanger bolt For roofing with corrugated eternit or sandwich elements, the S:FLEX sloping-roof frame with hanger bolts or solar fasteners enables friction locking and a positive-fit connection with the beam construction. This ensures the greatest possible protection of the existing roof membrane and creates optimum conditions for any necessary height adjustment.

This type of attachment is not only extremely stable, durable, weather and ammonia-resistant – the very good rear ventilation also helps to achieve a high degree of system efficiency.
