Y-Beams: strength and functionality for industrial and artisan spaces
The Y-Beams roofing system by Tesi System uses prestressed reinforced concrete elements shaped like an “umbrella,” spaced approximately 3 meters apart and alternated with curved metal or fiber cement sheets.
Upon request, a flat suspended ceiling can be added, resting on the beam bases, allowing the insertion of glass wool or mineral wool insulation mats, adaptable to ensure both standard and advanced energy insulation levels.
The combination of lightweight and essential materials ensures cost-effectiveness and reliability, while meticulous attention to construction details (hooks, joints, fastenings, etc.) guarantees durability and optimal performance.
