Beam NPS® Rei S
Mixed steel-concrete beam and column
The self-bearing NPS® Rei S Beam with a mixed steel-concrete structure and a concrete footing, is patented for optimal coupling with slab ceilings, and allows fire-resistant decks to be realised with no protrusions from beneath (according to DM 16.02.2007). The metal structure, made of S355J0 structural steel (UNI EN 10025-2) is made of one or more truss welded using metal active gas welding (Process UNI EN ISO 4063-131) according to NTC 2008 in force. Lower chords are inserted in precast class C28/35 concrete footing (UNI EN 206-1:2006), and equipped with reinforcement and surface reinforcement sized to support the heavy load of the ceiling on the NPS® Rei S Beams. Two galvanised metal profiles positioned on the sides of the beam and partially encapsulated in cast concrete act as housing for the ceiling and guarantee the lower surface in-plane.
