Hello. I hope that I am posting this in the correct section. My wife and I are going to remodel our 2 car garage into a family room and need to put up a grid so that we can hang drywall from it for the ceiling. We would like to do it so that the entire room is open with no support posts, but aren't sure what the proper size beems are to use. The garage is about 20X22 and we can't get anything bigger than 16ft in the area. We were thinking about putting a beam down the center of the garage at the 20ft length and running 11ft beams from the center to the ends of the garage. Is this something that could be done or is there a better way of doing this? Thanks.
