MTR® System

The innovative choice for an evolved building site

The MTR® System is the perfect combination between reliability and innovation in the field of steel-concrete composite structures. Innovative for the morphology, algorithm and calculation software, the system includes three typologies of trussed beams and is used to build horizontal structures for any type of construction. Among the steel-concrete composite solutions, the MTR® Beam represents the pinnacle in terms of technology and performance, outcome of experimentations and research carried out by the software house INFO.MTR, used by Metal.Ri to develop, experiment, and produce new technologies.

Certified building site industrialisation process.
Many advantages for: customer, designer and site manager, for “flawless” construction works.

The MTR® System substitutes, totally or partially, the use of primary and secondary beams with that of prefabricated composite beams, keeping, however, the building setting of a reinforced concrete structure. No more in-situ beams, but only steel-concrete composite beams, directly assembled on the pillars and reinforced at the junctions. Then, the assembly of the slab with its reinforcement and, finally, the casting takes place.


Why choose the MTR® System

A wide range of advantages to obtain the best result and satisfy any technical and economical requirement.

Rapidity of execution

The speed and ease of assembly of the MTR® System reduce the construction costs and times of the horizontal structures.

According to the typology of MTR® beam employed, there are the following reductions of time:

  • MTR® A by 70%
  • MTR® T by 50%
  • MTR® C by 70%

Sustainable and economical balance

With the MTR® System, there is a decrease in the processing on site.

The formwork is considerably decreased with the MTR® T beams and completely eliminated with the MTR® A and C beams.
The number of shorings and the use of formwork decreases as follows:

  • MTR® A by 100%
  • MTR® T by 60%
  • MTR® C by 100%

By reducing or totally eliminating shorings and formwork, the extra costs for the management of a building site are optimised.

Safety on site

The prefabrication of horitontal structures with MTR® beams improves the safety on site by 60%.

The use of the MTR® System in combination with any slab typology leads to 100% the prefabrication of the horizontal structure.

This total prefabrication ensures greater safety on site, driving down the risks and complexities related to overhead the assembly, typical to the traditional reinforced concrete solutions.

Product guarantee and earthquake resistance

MTR® beams are produced in the factory and arrive on site ready for the laying.

This guarantees a 100% certainty for the customer, the structural designer, and the site manager during the construction phases of the structure.
The MTR® element that is designed is the same that is produced in the factory, with CE marking, and easily assembled at a height with no need for skilled manpower.

Moreover, the MTR® technology improves the dimensional ratios within the beams/pillar junction, optimising the reinforcements in the strict respect of the resistances hierarchy.

Architectural freedom and versatility

The spaces are optimised thanks to the hidden beams, the reduction of the pillar sections, and the possibility to have wider spans.

You will obtain structures with broader meshes in comparison to those with traditional beams, structures with hidden perimetral beams, and the possibility to built architecturally complex structures.

In fact, steel, which can be easily moulded, allows you to shape the MTR® beams so as to satisfy any architectural requirement.

Concrete reduction

The MTR® Beams have reduced sections in comparison to the equivalent traditional structures made of reinforced or prestressed concrete, with subsequent reduction of the pillar sections and therefore of the quantity of concrete.

With the use of self-supporting MTR® A and MTR® C beams, the pillars will be even more reduced.

Fire resistance

The steel used for MTR® beams, coated or embedded in concrete, guarantees the structure resistance in case of fire, with no additional costs or processing.

MTR® C beams are native fire resistant (R);

MTR® T become fire resistant (R) if laid on a predalle slab system or on a formwork with the due concrete cover;

MTR® A beams are native fire resistant (R) with additional side steel rods or with bottom base treated with intumescent paints, fireproof plasterboards and coatings.

All the MTR® beam typologies are produced in the factory and arrive in the building site ready for the laying. They are not stocked before their assembly. They are directly transferred from the lorry to the pillars:
Less handling, which implies a reduction of costs and times.


The MTR® System includes three typologies of trussed beams and the related calculation system for the design.

MTR® A beam

Self-supporting during deck assembly and casting, with steel bottom plate.

MTR® T beam

Requires formwork and shoring during deck assembly and casting, without bottom plate and completely embedded in the cast in-situ concrete.

MTR® C beam

Self-supporting during deck assembly and casting, with concrete bottom base.

MTR® Software

The construction system of MTR® beams is equipped with a structural calculation software specifically produced and designed considering, on the one hand, the production process implemented in the factory in every single production phase, and, on the other hand, the respect of the technical regulations in force in Italy and Europe.

Construction phases of the MTR® System







Pre- and post-sale consulting

Our value added

The structural design with the MTR® System fits any designation of use, for the construction of residential, commercial, leisure, and industrial buildings. Contact us for a free technical consultation: an engineer of ours will become your MTR® designer of reference and will guide you in the choice of the MTR® element which suits your intervention, thanks to his/her expertise in the field of the design of composite structures.

The MTR® Designer will keep following you at all subsequent stages, from the modelling of the MTR® elements in your calculation programme, to the writing of the calculation report with the related graphic drawings, to the visit on the site to survey the measures, to the scheduling of the deliveries, to the provision of assistance during the laying phases of MTR® System elements.

Every building can be designed and constructed exploiting the technical characteristics of a single MTR® beam typology or using more typologies at the same time. A wide range of possibilities to obtain the best result and satisfy any technical and economical requirement.
