Many people ask the question; why do people use steel frames for construction when they don’t need to, even though they’re so expensive? Well, the argument in favour of it is quite a long one, so be prepared for some boring details.
Steel frames, have far greater strength than, say, wood. There are other areas in which wood beams can provide better functionality, such as with insulation, but using steel frames can allow you to place more weight on the support structure, meaning that you have more options for building your home. There are other areas where there is still a lot of debate about, such as which is better in a fire emergency, or which is most durable, but it is clear that higher demands of a building require something stronger than what wood offers. You also get to avoid the chance of rot, which is a common problem which arises with wooden beams.
