These beams are the best solution where buildings require fire-resistance.
The concrete bottom plate, whose dimensions are conveniently realized, functions as formwork and support for the floor.
The MTR® C Beam is suitable for any kind of floor or vertical structure, both selfsupporting and non self-supporting structures, to build shopping centres, multistorey parking, hotels, convention centres, schools, bridges and industrial buildings.
The beam is designed in our factory. It is self-supporting during the assembly and casting phase of the floor so it avoids using formworks and props. Its static behaviour depends on the two different building phases of the structure:
Phase 1: until the concrete consolidation, the MTR® C is self-supporting and functions as an isostatic lattice metallic structure.
Phase 2: after the concrete consolidation, the MTR® C beam is tied to adjacent structural support members. It becomes a hyperstatic structure with a resistant composite steel-concrete section. The bottom-chords are embedded in the concrete plate whose size and concrete quantity are designed accordingly.
