NPS^® REI S Beam

The self-bearing composite steel truss and concrete NPS^{^®} REI S Beam with 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 Eurocode 2-2.

The metal structure, made of structural steel (UNI EN 10025-2) is made of one or more truss welded using metal active gas welding (Process UNI EN ISO 4063-135).
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.

Technical data

Metal structure	Made of structural steel in conformity with UNI Standard UNI EN ISO 10025-2
Footing	C28/35 or higher class concrete (UNI EN 206-1:2006) designed and equipped with reinforcement and surface reinforcement. Two galvanised side metal profiles partially encased in cast concrete act as housing for the ceiling and guarantee the lower surface in-plane.
Casting framework	C25/30 when not otherwise noted by the designer
Self-supporting	Yes. NPS® Rei S Beam bears itself and the ceiling that rests on it, already from the moment it is placed on the column (1st phase), already before the formwork cast (2nd phase)
Welding	Using metal active gas welding (Process UNI EN ISO 4063-135)
Mechanical resistance to fire ( R )	Up to 120 minutes
Standards referenced	In the 1st phase Eurocode 3 In the 2nd phase Eurocode 4 For anti-seismic Eurocode 8
Design	Elaborated with the System calculation procedure conforming to the current Standard, and signed by a qualified technician.
