Single-flight or multi-flight with intermediate landings on single posts made from structural profiles, towers or lattice frames, depending on the specific application, or by support brackets. Stairways for railway embankments.

  • Fences
    Fences

    FRP fences for perimeter security. Made with pultruded profiles and grating, or with mesh. They offer electrical insulation, corrosion resistance and non-magnetism, with no maintenance required. Mesh fences are radio transparent and frangible. Can be fitted with barbed-wire toppings and CE-marked gates up to 8 m.

  • Gates
    Gates

    Gates made with profiles, grating or mesh in FRP. Lightweight, dielectric and resistant in corrosive environments, they are factory-prefabricated and require reduced maintenance.
