Aluminium is one of the traditional structural materials. Structures made from the aluminium alloys are widely used in the civil engineering for erection of new civil and industrial buildings and reconstruction of just existing. Increased corrosion resistance, stability of mechanical properties at negative temperatures, lightness and increased durability are the main advantages of aluminium alloys as the structural materials. Aluminium alloys are used for load-bearing structures of light frameworks, for structures of facades, molds of columns, floors and load-bearing walls, structures of stairs, doors, partitions, balconies and other structures
