A question I have is more a curiosity. We have skyscrapers and tall buildings made of steel, but why is it whenever I go look at some housing projects and developments, those houses are built with wood frames? Right away I think of cost which is probably the most obvious answer, but I am not sure. Could there be other reasons? Steel has far more tensile and compressive strength than wood, melts at higher temperatures than wood, and I would guess steel has some thermal properties which make it better than wood though I am not totally sure on that. I would also think steel is more eco-friendly as wood is chemically treated. Even with some of these properties, one might think why not build houses with steel?
