I bought my 40x50 red iron building from Alabama Steel and they were great. Chris, the salesman, really went above and beyond to educate me and make sure I knew what was going on. I was a high maintenence customer because I have never dealt with a steel building before and I was using a contractor to erect it that did not have prior experience either. Their prices are transparent and as good or better than online sellers for the same product but better service.
