NPS® Truss - Стальные фермы

NPS® Truss beams are steel trusses for the construction of pre-assembled steel-concrete composite beams.‎ They must be supported during construction, but provide high fire resistance.‎ They are suitable for use with predalles type slabs as they do not require any additional formwork as a result of the latter's slab work.‎ The fire resistance is due to the in-situ concrete that completely encases the truss and protects it from direct exposure to high temperature gases.‎ This results in trusses with a high degree of prefabrication and fire resistance characteristics.‎ Further info from manufacturer on NPS® Truss Tecnostrutture
