Beam NPS® CLS
Mixed steel-concrete beam and column
The self-bearing NPS® Cls Beam with a mixed steel-concrete structure is fire-resistant in conformity to DM 16.02.2007. It is ideal for fire-resistant structures with large overloads and/or spans; it is particularly suited to coupling with hollow core slab or slab ceilings. The metal structure, made of S355 structural steel (UNI EN 10025-2), is made of one or more trusses welded using metal active gas welding (Process UNI EN ISO 4063-131) according to current NTC 2008. The lower chords are inserted in a class C28/35 concrete footing (UNI EN 206-1:2006), precast and equipped with reinforcement and surface reinforcement sized to support the load of the heavy ceilings on NPS® Cls Beam.
