JYS Roof trusses are used in a broad range of buildings, mainly where there is a requirement for very long spans such as in airport terminals, aircraft hangers, sports stadium roofs, auditoriums and other leisure buildings, etc., or to carry heavy loads, i.e. trusses are often used as transfer structures. Our trusses comprise assemblies of tension and compression elements. The top and bottom chords of the truss provide the compression and tension resistance to overall bending, and the bracing resists the shear forces. A wide range of truss forms can be created according to your requirements. Each can vary in overall geometry and fit many extreme climates and terrains.
