Steel is a more reliable product than wood. Steel will never warp as much as wood. Steel will also never be attacked by insects. Compared to wood, steel is several times stronger. Although steel is a stronger and more reliable product than wood, it has disadvantages that explain why steel is not used in homes. Steel costs much more than wood. Steel also weighs much more than wood. Steel is therefore more difficult to work with than wood. Steel also cannot be used in homes as they are built today. There is no easy way to use steel as studs or attach drywall to steel. Steel is also extremely conductive, which is why it doesn't hold up well.
