The construction sector uses 1.2 million tons of aluminum in Europe, 1.05 million tons in the US and915,000 tons of aluminum in Japan annually. Aluminum is used in roof and facade of buildings, doorsand windows, stairs, roof frame, construction scaffoldings and greenhouse construction.
Aluminum was first used in quantity for building and construction in the 1920s. The applications were primarily oriented toward decorative detailing and art deco structures. The breakthrough came in 1930, when major structures within the Empire State Building were built with aluminum (including interior structures and the famous spire). Today, aluminum is recognized as one of the most energy efficient and sustainable construction materials. The estimated recycled content of aluminum building materials used today is between 50 and 85 percent.
Use of aluminum helps building projects qualify for green building status under the Leadership in Energy and Environmental Design (LEED) standards.When used for construction, aluminum structures can weigh 35 to 65 percent less than steel, while providing equivalent strength. The modern skyscraper could not be built without aluminum.
Corrosion-resistant aluminum bridge decks require no painting, minimal maintenance and, unlike concrete, require no extension framework or cure time.
Aluminum can provide insulation and allows daylight and fresh air into buildings. Strengthened alloys can support large glass structures and solar panels.
