Aluminium is an incredibly recyclable material, which makes it one of the best construction materials for environmental sustainability. Aluminium is widely used in the building because of its intrinsic properties of lightness and corrosion resistance. Aluminium is used in external facades, roofs and walls, in windows and doors, in staircases, railings, shelves, and other several applications. Aluminium's high strength-to-weight ratio is one of its major advantages in the construction industry. Aluminium has a density of 2.7, which means that it is a third the density of steel. The strength of the metal can be adjusted to suit the application by proper alloying. Find aluminium construction materials here.
