Tavel to any of the developed countries in the world and it is not uncommon to see buildings made of steel. In fact, the use of steel in construction has caught on in a big way in a lot of countries. It is difficult to find a high-rise building in western countries made of concrete alone. A predominant portion of high-rise buildings there are built using steel, while concrete is also used in the construction. Some fine examples of buildings where steel has been extensively used include the World Trade Centre, the Burj Khalifa and the Petronas Towers. The concept of using steel predominantly in construction is, however, yet to catch builders' fancy in countries like India, though it is a matter of time before the Indian construction industry wakes up to the fact that using steel can not only improve efficiency of a building but can be cost-effective too in the long run.
