How important is iron for the modern construction industry?

Modern construction work will be reduced to almost nothing if not for iron and steel. Want to know why? Let us take a look.

If you have visited a construction site, you will see a lot of large girders. The framework of steel girders that you see in the buildings under construction is designed to bear the weight of the building. Without this framework, buildings made from just stone or brick would have to have very thick walls at the bottom. This would limit their height.

Iron plays important roles in other construction activities too. Cast-iron is used to make buildings and fences, while railway tracks are made of steel. Iron is also an ideal material for building bridges.

The first iron bridge was built in 1778, and in 1818 the first iron ship was launched. You all know about Paris’s famous Eiffel Tower. This 300 metres tall tower is built of latticed iron. The uses for iron and steel in construction are many, and continue to expand as the years go by.
