My little corner on metal building kits
you will probably have to install interior columns. Metal garage buildings designed this way are often called "modular" steel buildings although the term only refers to the separate pieces between columns. In most other ways however, they are nearly identical in construction to steel buildings. You may either opt to have finished interiors in your metal garage buildings or you can leave it as it is. Some manufacturers will provide interior finishing as an option, while for other designs will require you to furnish your own interiors.
