Reliable fastening systems – guaranteed watertight roofs


All S:FLEX flat roof mounting systems can be installed without roof penetration and are available as aerodynamic/low-ballast systems, as ballasted frames or with concrete foundation.

Our aerodynamic LEICHTmount systems require only minimal additional ballast and are the ideal solution for quick installation and for roofs with low pressure/load-bearing capacities.
Our ballasted system based on the S:FLEX Delta triangle allows installation with higher ballast quantities if necessary.
Our Delta Concrete system is the solution of choice for installations on flat concrete roofs with parapet walls.
And for quick and easy PV mounting on green roofs we offer the S:FLEX GreenLight system.
