Large span cable bridge includes large span tread, frame, wiring duct, heavy-duty tread, right-angle tees, multi-section tees, right-angle mounting rods, and corresponding types of connectors, covers, and pillars. Since the full cable bridge with cover is included, please specify when ordering or select based on the type of cover. The surface treatment of the large span cable bridge is divided into two parts: spray painting and galvanizing. Under corrosive conditions, choose a bridge with spray painting; under general atmospheric corrosion conditions, choose a bridge with galvanizing. The brackets for wall-mounted equipment are fixed with expansion bolts, and the spacing of the brackets should not exceed 2 meters.
