Metal structures applied to the civil sector

Metal carpentry: the art of producing steel structures

Prefabricated steel structures for the civil sector

RIBERI P. COSTRUZIONI in recent years has expanded its production related to metal structures also to the civil sector.

The steel construction system is based on a wise approach to building construction that meets appropriate performance standards in terms of seismic safety, durability and eco-efficiency.

In addition, steel structures allow precise management of construction times and reduced use of resources, resulting in economic benefits.

In addition to these, the easy integration of insulating systems and plants, which makes it possible to largely meet the required energy, acoustic and fire resistance requirements, as well as the possibility of reusing the components and completely recycling the material, resulting in the competitiveness of steel constructions also in terms of environmental sustainability.

Shorter lead times

Thanks to the industrialization of the building process, from design to construction site, where all structural elements and envelope systems are made in the company, ready for installation, with extreme ease of assembly, construction times are reduced by 50 – 60%.

Since it is a dry construction, daily problems and long drying and curing times for plasters and screeds typical of the traditional building site are no longer needed.


The rapidity of construction together with the optimised design result in a reduction in financial costs, with a rapid return on investment and the time when the building starts to perform

Moreover, thanks to the mechanical characteristics of steel profiles, much lighter structures are obtained. The lightness guarantees a reduction of costs concerning foundation works, excavation and casting volumes.

We would also like to point out that the incidence of labour is lower: activities carried out on site cost twice as much as those carried out in the workshop.

Comfort, Health and Durability

Thanks to the technical-constructive solutions applicable to dry steel construction and the materials used, it is possible to achieve very high energy performance for Class A buildings.

The high thermal-acoustic insulation ensures the quality of the indoor environment. Systems, such as heating and/or renewable energy systems, are also easily integrated into the structure.

Furthermore, since steel is not a moisture conductor, it guarantees healthy environments without the so-called “sponge effect”.

Dry steel solutions do not require maintenance and the treatments to which the profiles used are subjected guarantee their anti-corrosion properties with consequent durability of the building.

Seismic Safety

Structural systems based on very ductile materials, an intrinsic characteristic of steel, are able to withstand earthquakes and are much more advantageous than those based on less ductile materials, such as reinforced concrete and brickwork.

In very high seismic conditions, the lightness of the structure and its ductility guarantee high levels of strength and any restoration and maintenance work will be null or void, unlike more rigid structures, such as those using concrete, which are difficult to monitor after the earthquake.

Dry-connected shell systems, with connections capable of supporting movement during an earthquake, offer considerable advantages that also limit possible damage to non-structural components

Fire Risk

Steel drywall buildings have a higher passive fire resistance than other industrialized building systems using other building materials.

The steel structure is almost always placed inside cavities that already have insulation such as plasterboard slabs, which provide excellent fire protection. In case there are other needs, it is possible to use particular slabs that reach very high fire resistance parameters.

The steel structure can be treated to have a correct fire resistance according to specific needs, in case it is left exposed, a protective treatment can be made


The environmental impact of a dry construction is reduced both during the construction phases and at the end of the useful life of the building organism, thanks to the high percentage of recovery of the single components, mechanically assembled and not wet construction.

In addition, the industrialization that distinguishes the dry steel solution guarantees:

  • overall energy saving for the same number of square meters built compared to other building solutions;
  • reduction of packaging and waste;
  • possibility of reuse of building components;
  • no use of raw materials: the steel used in construction comes from recycled material;
  • recycling: steel is the most recycled material in the world and is 100% recyclable, it can be recycled countless times without losing any of its original properties;
  • increased safety at work;
  • reduction in the transport of both goods and labour;
  • Prevention of climate change: CO2 emissions to produce and transform steel products in the workshop account for less than 3% of total national greenhouse gas emissions.

Flexibility and Customization

The versatility of the constructions offered by Riberi P. Costruzioni allows the client and the designer to define the characteristics of the building by adapting them to the construction site and to personalize the functionality and design of the finishes and infillings.

In addition, in view of future new requirements and changes in use, the steel dry construction system is ideal for the expansion and raising of the building.

In the choice of materials for the elevated structures, having to pay particular attention to the load-bearing capacity of the roofing slab, it is essential to avoid heavy structural interventions, thus preferring the lightness and high performance of the steel dry solution.

Building site

A steel construction site is a “clean” construction site that employs a skilled workforce.

Prefabrication in steel allows sites to be much more organized than those related to buildings built with other traditional technologies, as they are industrialized structures, for which the work on the ground is limited to assembly and assembly of construction components.

It is also possible to intervene in confined spaces and in unfavourable conditions. This makes it possible to carry out not only ex novo interventions but also extensions, elevations or recovery interventions with the minimum possible impact.
