Iron+and+Steel

Do you think metals are "cold" materials?
=== Yes I think that very much, materials like wood are called warm materials because they can maintain the heat inside de houses. By the other hand I think it is also because of its colors, they are all metalized ones. ===

My opinion:
=== At the same time as the stone left behind the wood, the steel also left behind the iron. Iron was left behind because of its disadvantages, steel is stronger and weigh less than iron. Also the new tendencies or fashion in the modern architecture look for skyscrapers and no iron and not so tall buildings. I think that with the new needs of the people, of larger and extreme buildings, the steel is the perfect material to use in project, but let’s not forget the beautiful old iron buildings and structures arranged all over the world ===
