Do you want to build a garage that is capable of housing a mechanic's workshop? If so, you will need to install steel beams in the ceiling and walls to withstand the weight of a motor or car lift. Where do you get the steel beams that you need? How do you know what size beams you will need? Can you install the beams yourself, or do you need a professional contractor to do it for you? You can learn all of this on my website. There, you will see each step that I followed when constructing my mechanic's garage.
