Libera 76 Truss system

Libera 76 truss system

LIBERA is the only flat aluminum truss system in the world that can easily be used to create and build load-bearing structures in a virtually infinite number of shapes. The LIBERA System consists of “constant” elements (FL76 fl at beams) and “variable” elements, which make it extremely versatile. LIBERA is compact, modular, strong, reliable, easy to transport and convenient to store. LIBERA cuts your shipping costs to a minimum. LIBERA roofing sheets are available in various lengths, finishings and colors. LIBERA can also easily combine with our high tech RL76 high load truss range with forked connections.
