The global construction industry is expected to reach an estimated value of $10,388.6 billion by 2019.

Opportunities in the global construction industry include:

  • Strong economic growth in developing nations, such as China, India, and the Middle East countries, is expected to further drive infrastructure development
  • Growth due to the positive impact of new green/environmental standards in first world countries
  • Global population growth means an increase in the urbanization rate

Appearances of modern cities and towns have greatly been influenced by the use of Aluminium in construction. Aluminium is light and strong and can be given virtually any desired shape. Looking at the global end use of aluminium in 2014 (chart below), the construction sector was the second largest consumer of aluminium with 25% of all aluminium produced worldwide used in construction.

China’s aluminium usage in the construction industry

China is the world’s fastest growing economy. Over 46% of China’s soaring GDP comes from the country’s rapid industrial growth. This industrial growth is predominantly driven by the massive urbanization taking place which is increasing demand for aluminium and the raw materials used in its production. Due to unmatched growth rates, China, which now plays the dominant role in the global aluminium market, is expected to remain the world’s largest aluminium consumer throughout the next 10-15 years. Already accounting for about a half of global aluminium consumption, China is forecasted to boost this share to 59% by 2025.

Aluminum is considered a vital component of green and sustainable buildings for several reasons:

  • Maximization of natural light – heavy glass windows are easily supported by high-strength, low-weight aluminum frames.
  • Aluminium is easily recycled and loses none of its properties during the process.
  • Aluminium can be used in any climatic conditions and does not lose its properties in temperatures ranging between –80 °C and +300 °C.
  • Aluminium structures become even stronger at low temperatures. That is why it is widely used in construction in cold areas like Siberia in Russia.
