Steel is one of the primary materials in the construction industry because of its high strength, durability, relatively low weight, fireproofness, and weather resistance. Its remarkable versatility (strength and ductility) enables its use in various structures and components, from frames and columns to roof trusses and beams.
Environmental impact
The steel production process generates air pollutants, such as, for instance, sulfur dioxide, nitrogen oxides, and particulate matter, waste (e.g., steel slag), and is associated with significant water consumption. Moreover, the process is energy-intensive, and its general energy consumption is estimated at 10 GJ/t of steel produced (exact values depend on the type of steel, its finish, application, etc.).
