Iron+and+Steel

The iron brings us the opportunity to mold it to any shape that we want. It is strong in compression, reason of why it can be used on the columns of the building, because it helps them to resist more the constructions’ weight to prevent accidents, but it is fragile in tension, breaking easily without warning. It can be used in Arch bridges and in construction of machineries. The steel is made of iron and a little bit of carbon. These combination give to the material the property of be strength, being resistant in compression and in tension. It can be used to reinforce the s tructure on skyscrapers, suspension bridges and others.
 * The iron and Steel** are two important metals used as materials for constructions. They offer more resistance to the structure of any building and present some characteristics that make us use them for specific situations.

“//the old cast iron buildings died out. I'm not really sure whether the new skyscrapers killed them, or the new esthetics//” I think that the old cast iron definitely passed to the history as a construction material. As years go by other proposals of better materials appears, and nowadays we can find and use new ones that are equal or more efficient than old cast iron, that allows us to create modern and attractive designs improving the esthetic of constructions and that offer more possibilities to be acquired.
