S:FLEX LEICHTmount - Delta Concrete Raised Flat-Roof Mounting Systems

SHARE

The advantages of the S:FLEX Delta Concrete: The Delta Concrete is designed to be used on flat concrete roofs and offers the possibility to build over obstacles in order to optimise performance per area. Lightweight, material-efficient design makes the Delta Concrete a modular and flexible system with few components. Almost all framed and frameless module types with common dimensions – especially bifacial modules – can be installed either in landscape or portrait mode.
