All metals shrink and expand due to the ambient temperature, but at different rates depending on the metal and alloy content. There is a 30 foot long aluminum beam at the Ontario Science Centre in Toronto that accurately tells the temperature within 1/8 of 1 degree Fahrenheit based on this principle.

Yes, it does. It's coefficient of expansion is rather low, so it would take a large piece of steel to expand very much. When you drive over a bridge, ever notice those things that look like big zippers that go across the road? They are built into the bridge to allow for expansion and contraction as a result of tempurature changes...
