Rack structures include槽式电缆桥架、tray-style cable racks, ladder-style cable racks, and grid racks, composed of brackets, supports, and installation accessories. They can be independently installed or mounted on various building and pipeline supports. They feature simple structure, aesthetic design, flexible configuration, and easy maintenance. All parts require galvanizing treatment. For outdoor installations on buildings, if near the seaside or in a corrosive area, the material must possess anti-corrosion, moisture-resistant, good adhesion, and high impact resistance properties.
