TR Toscana is specialized in the realization of trusses with large spans, with fixed or variable longitudinal curvature.
Often used in the covering of sheds, this type of TTR is very appreciated both from the architectural and structural point of view.
For the realization of first category bridges or gangways, the most suitable product is certainly the Arch TTR Beam with formwork. Just the formwork, in fact, allows, once the beam is laid, to perform immediately the casting without the need to use docks, which in case of vacuum below can be difficult and expensive to achieve.
TTR Arch or Truss beams can be made with or without formwork.
