Everything burn out, but they not know very well about properties of steel at that time. They also had no other choice because concrete evolution was not very remarkable at that time.
Now days for construction steel structures are used throughout the world. Steel structures are preferred over concrete where structure is based on frame. What engineer does in case of concrete?

He took sections of steel to the field and placed these different sections. Where ever he wants, but this will not be possible in case of concrete.

Steel structures have some overriding properties as compared to concrete, but there also some properties in which concrete structures are dominant.

Therefore steel has some;
