Bridge structures are categorized into槽式电缆桥架(slab type cable bridge), 托盘式电缆桥架(tray type cable bridge), 梯级式电缆桥架(ladder type cable bridge), and grid bridges, etc., composed of brackets, support arms, and installation accessories. They can be independently installed or mounted on various building or pipeline supports. They feature simple structure, aesthetic design, flexible configuration, and easy maintenance. All parts require galvanizing treatment. For outdoor bridge structures on buildings, if they are near the seaside or in a corrosive area, the material must have anti-corrosion, moisture resistance, good adhesion, and high impact strength.
