Commercial Sectional Overhead Doors
Sectional doors run everything from fire stations to fleet garages to loading docks. We install the right lift, and we fix the springs, cables, and panels that take the abuse.
Commercial Sectional Overhead Doors in Sacramento & Northern California
A commercial sectional overhead door is built from hinged panels that ride on rollers up a track and back along the ceiling. The track configuration — standard lift, high lift, or vertical lift — is chosen to fit the building, and the panels can be insulated steel, non-insulated steel, or full-view aluminum with glass. Because the door weighs hundreds of pounds and is carried by torsion springs and cables, failures tend to be sudden and the door is dangerous to move by hand once something breaks.
Guardian Door LLC installs, repairs, and replaces commercial sectional doors across Sacramento and Northern California for fleet and municipal garages, fire and EMS stations, warehouses and docks, auto dealerships and service bays, and industrial buildings. We handle torsion springs, cables and drums, rollers and hinges, track and struts, panel replacement, weather seals, and commercial operators and safety devices.
