Aluminium, as a lightweight metal, which has only one third of the weight of steel and iron. So, the final structures are lighter and, subsequently, this leads to reduction of energy consumption and construction costs. With a tensile strength of 200 MPa, aluminium offers a strength similar to that of mild steel, which increases the safety of buildings and reduces risks from natural disasters. Aluminium's high resistance to corrosion is due to the presence of a protective oxide layer on its surface, which prevents further damage to the metal. In addition, aluminium is known to be a fully recyclable metal which is recycled without any loss of properties. This feature is useful in reducing environmental pollution. This advantages has caused a widespread usage of aluminium profiles in the building industry, which is used in almost all exterior and interior parts of buildings.
