Steel vs. Concrete
For the longest time, the construction industry largely meant lots of cement and reinforcing bars (rebars). Architectural finishes may have changed based on social trends but the cores of most buildings have remained to be based on rebars encased in solid concrete. These days however, metal buildings have risen and I think that it is something worthy of mention in this page. Steel makes a building construction faster and the structure ends up more lightweight and stronger compared to concrete buildings.
