Strutture & Soluzioni Libera 76 Roof system
LIBERA FL76 - 15x11m(49.21’x36.09’)
SINGLE-PITCH
LITEC has always been a forerunner in the search for safe and high-performance roof systems. The solutions available come in many dimensions and typologies; from the smallest roofs with the lightest loads to the grandest of ideas with high load bearing capacity on wide spans. These structures are easy to build and consist almost entirely of standard components. They are equipped with self-extinguishing roofing sheets, wind bracing kits and ballast accessories.
LIBERA is an open structural system. LIBERA 76 roof systems consist of Maxitowers and a LIBERA FL76 grid structure. With the single-pitch roof, the upper grid structure consists of trusses with built-in LIBERA FL76R roofing sheet guides.

LIBERA Alusfera 2
Alusfera is another way of using LIBERA, again starting from standard components with the addition of a few special accessories. It is a very impressive structure that may be used purely as part of the scenery, even without roofing sheets. Compared to the first version, Alusfera 2 has been designed with the addition of frontal and rear arches, a new ridge, a new solution to secure the main arches to the ground and alternative set-up options.

LIBERA Tunnel
22x19m (72.18’x62.34’)
Not just straight: LIBERA can be curved and used to create rounded components simply by adding small accessories to the truss. With simple stratagems you can go from flat systems to arched systems and vice versa. Tunnels may be created with front or side roof ridges.

Terrace stand roofing
This roof system for sports is derived from the LIBERA modular concept. It uses trapezoidal flat section trusses, which give the structure a streamlined look and the necessary slope for water to run off. Being a completely overhanging roof, it does not need support pillars. Maximum overhang is 8 meters (26.25’) from the back wall, provided the stand structure is sufficiently ballasted.
