It looks that the I-beam is constructed to form exoskeleton for hanging flooring and attaching glass curtains. Interesting facts: Australia exports the most metal to the rest of the world that amounted to USD72 billion in 2012, including iron (ingredient to production of I-beam). Australia imports second most Structural Metal Product (ISIC2811) in the world and it is amounted to USD 3.3 Billion in 2012 Major trade partners of Australia are China, Japan, USA, Indonesia. In the most simplified manner, iron is mined in Australia. Then, they are shipped to say, China and Indonesia. Structural metal product such as I-beam is manufactured and shipped back to Australia. One of the uses of I-beam is in building construction. This typical example illustrates the fact that building materials are the products of globalised economy.
