Why build in steel?
Steel is long lasting!
Steel is an artistic expression that endures over time. It maintains its technological and mechanical properties consistently, and these are easily monitored at any time. The preservation of these characteristics is independent of the structure’s assembly conditions, and many types of steel surfaces require no protective treatment. Metal structures absorb seismic energy using the material’s inherent high plastic reserves: from a technical standpoint, this translates into less expensive construction details and significantly lower structural weights than similar solutions made from traditional materials. The ability to withstand significant dynamic loads relative to the structure’s own weight makes steel the most suitable material for the construction of road and railway bridges, thus reducing their environmental impact. Furthermore, all products made from steel are required to carry the CE marking.
Steel is earthquake-proof!
The elasticity and ductility of steel are the qualities necessary to absorb seismic stresses. Furthermore, steel is an isotropic material, meaning it has the same resistance to tensile or compressive stresses, longitudinal or transverse stresses. Furthermore, steel structures are lighter, thus limiting inertia forces proportional to the mass of the structural elements.
Steel is safe!
Because it has excellent resistance to fire and corrosion. In the event of a fire, a structure made of steel beams can withstand very high temperatures, also allowing for easier identification and repair of damage. With adequate mechanical (protective paint) and electrochemical (cold or hot-dip galvanizing) protection, a steel structure can also resist corrosion for many decades.
Steel is cheap!
Steel is economically competitive for several reasons: from speed of construction to reduced maintenance costs, from rapid payback to savings in material usage, from reduced foundations to the use of standard steel products for limited construction areas. It allows for significant savings in construction time and costs, and thanks to the use of prefabricated structures, pre-inspected in the factory, and the ease of assembly on site, solutions can be delivered in record time. Steel structures, lighter than concrete ones, also require shallower and more complex foundations, which are therefore more cost-effective. The lightweight nature of steel profiles requires smaller foundations, resulting in lower costs: the lightweight nature of steel structures allows for reduced excavation, concrete, and backfill volumes, other important factors to consider when assessing construction costs. This also translates into cleaner (thanks to earlier workshop processing) and safer (limited need for machinery and equipment) construction sites.
Steel is flexible!
Because it easily adapts to a variety of design needs, such as architectural transformations, expansions, renovations, and additions. The extreme mechanical precision of steel structures allows them to address any type of project, achieving significant benefits in terms of the building’s durability and profitability over time. Only steel allows for the restoration of historic buildings thanks to the possibility of even localized reinforcement of pre-existing structures with elements that are non-invasive, both architecturally and in terms of the building’s usability.
Steel is expressive!
Due to its technological characteristics, steel allows for expressive freedoms unknown to other building materials. Thanks to the compact size of its structures and profiles, steel allows for maximum use of available surface area, allowing the designer complete freedom of expression. The ability to design very large interior spaces without intermediate support structures is undoubtedly the greatest potential of steel. Its easy combination with glass also allows for the creation of large, bright surfaces and the creation of spaces difficult to achieve with more traditional materials, leveraging natural light to achieve highly elegant effects.
Steel is eco-friendly and sustainable!
Steel fully complies with the principles of recyclability and durability. The life cycle of a steel building is significantly longer than that of a traditional one, and even any changes in intended use have a significantly reduced environmental impact. Environmental sustainability means recyclability and durability. Steel is the most recycled material in the world, with 14 tons recycled every second. Italy is the leading European country for ferrous scrap recycling, with an average of approximately 20 million tons of material annually remelted in national steel mills. After its structural functions are exhausted, 100% of the scrap steel is recycled (without losing any properties), and 99% of the profiles (both flat and long) are recovered as they are easily separated from other materials. Steel therefore contributes, directly and indirectly, to the conservation of natural resources.
