The physical properties of aluminium make it an ideal material for construction. It is light, strong, durable and requires minimal maintenance.
- Light weight means less strain on supporting structures, easier handling and reduced transport costs.
- High strength means less mass for a specific performance.
- Resistance to corrosion means a longer building life even in aggressive environments. Common industrial pollutants such as ammonia, carbon monoxide and carbon dioxide all have very little effect on aluminium. Aluminium is also excellent to use in coastal and marine environments because the effect of sodium chloride on the metal is minimal.
- Formability means that architects have an infinite range of design possibilities. It can be cast, rolled and forged as well as extruded to be formed into an unlimited number of shapes. Extruded sections are particularly well defined with clean edges and fine detailing. It can be curved, tapered, welded and cut to the most challenging and dynamic geometries.
- Durability means that buildings have a long life with reduced maintenance requirements. Non-toxicity means that aluminium is safe for plants, animals and humans.
- Like most metals, aluminium does not burn and can be used to help provide fire resistance where appropriate.
