Poligon shelters are bolt-together tubular steel frames, with a powder coat finish, that require no field welding. Roof decks are of either metal, tongue and groove southern yellow pine or structural insulated panels (with grooved beaded ceiling). This pre-engineered package is shipped as a knocked-down pre-fabricated kit that includes the structural frame, roof deck, fasteners, trim, optional ornamentation and installation instructions. Smaller shelters can be erected quickly by maintenance crews or skilled volunteer labor. Most large Poligon structures require professional installation. Footing details are designed by an engineer retained by the owner, or a Poligon engineer.
