From my head on commercial steel buildings
A building made of wood would be vulnerable to several types of pests and not to forget fire all of which is hard to contain once spread. Due to the nature and building style metal buildings are also much more safer in an earthquake or hurricane situation. Metal building are also more durable and capable of supporting the immense weight of skyscrapers compared to buildings made of wood which can only support a couple of floors. A common man would generally associate metal buildings with huge structures such as shopping complexes and huge indoor stadiums. This is however now a fact of past as even households and people looking to build homes and small offices are also opting for metal buildings structure.
