Where it all began. The very first Manning Building Supplies facility opened in Ocala in 1979 and today, over 40 years later, it is home to our most state-of-the-art facility. The modernized location features a full suite of building supplies and services including a truss manufacturing plant and showroom. We proudly serve the Marion, Alachua, Citrus, Levy, Sumter and Lake County areas with expert job support and unparalleled customer service.
