Surely these metal structures are valuable works, built and designed to last over time, stable and safe.
They add a remarkable architectural and aesthetic value that enhances and rewards the context in which they are inserted.
The vast majority of steel structures for civil/industrial construction are made of steel, welded or bolted together, and used for many purposes such as new construction, extensions, renovations, elevations, earthquake strengthening.
The steel used in the construction of these metal structures and joinery works is of the "S" (Structural) type, characterised by its increased ease of use, ductility and strength.
This detail is evident in the case of earthquakes, fires, wear and tear and weathering.
