Question

Even iron get rusted we are using for constructing buildings as traditional metal is it correct or incorrect suggest alternate metals

Answer 1

Rusting does not occur if it doesn't come in contact with atmosphere.In buildings it is covered by cement in such a way that it doesn't come in contact with atmosphere and get rusted.It is hard so we use it in buildings.So, it is correct. I don't think any other metal is as cheap as iron.

Answer 2

do you know that there is an iron pillar near qutub minar which was built by I think king Chandra which has not rusted for almost 1500 years (I ain't sure) . Isn't it wonderous!!! I have observed that indians would have developed the ability to prevent the iron from rusting several years ago!!!!!!!!
