In civil and industrial construction, there are construction technologies that allow for creations that increasingly combine the requirements of technical regulations with architectural and energy requirements.
Arcalab proposes these solutions as an alternative to traditional masonry and reinforced concrete constructions.

Buildings made of wood, steel and wood and finally steel, wood and glass can offer numerous advantages. Both steel and wood structures guarantee high resistance to earthquakes since the masses of the resistant and inertial gravitational structures are much lower than those of masonry and reinforced concrete structures.
Wooden buildings already use the resistance characteristics of steel mainly in the creation of connections and for bracing. In the principle of economy, mixed solutions can be studied where the vertical structures of the steel frame are associated with horizontal structures composed of laminated wood beams and plank floors; on the site you can find some of these solutions.

Steel can also be used for elevated structures or horizontal structures when particularly limited space is required. Solutions with mixed steel-concrete floors guarantee this type of functional requirement and offer functional solutions for the installation of technical systems. Steel is a material with high elasticity and mechanical resistance, easy to transport and assemble, which can be assembled dry and for this reason it is easily used combined with wooden structures that have the same prerogative. Usually, steel is used for the construction of buildings that develop vertically, as in the case of multi-storey apartment buildings, or in the industrial field (sheds); however, the construction system can also be used efficiently for conventional residential construction. In both construction systems, wood and wood and steel, the load-bearing structure may or may not be left exposed. At the end of its construction, the building has the same characteristics as a traditional brick or reinforced concrete building, but steel and wood homes are truly prestigious properties and are ideal for those who want to improve their quality of life: The possibility of leaving part of the structure exposed offers architects and engineers highly modern and contemporary architectural solutions. From an energy point of view, highly energy-efficient constructions are possible thanks to the use of insulation (of natural or artificial origin) and prefabricated wall packages composed of OSB panels, wood fiber and laminated wood uprights.
All this allows for very short construction times and high industrialization of the finished product; in fact, even the plant engineering part is integrated into the prefabricated paneling.
Steel and wood are therefore not only used in the construction of lightweight, fire-resistant roofs.
