The installation can be adapted to local conditions. It can be laid overhead along with the process pipeline; it can be hoisted under the floor and beam; it can be installed on the wall of indoor and outdoor, column wall, tunnel and cable trench. It can also be installed on open columns or buttresses. When the large multi-layer bridge is hoisted or erected, the I-steel column should be laid symmetrically on both sides as far as possible.

The cable tray can be laid horizontally and vertically; it can be turned, T-shaped and cross shaped branches; it can be adjusted in width, height and diameter.


3、 Selection of surface treatment

Cable tray is a thin-walled steel structure, in order to adapt to different environmental requirements and have a long service life, our company has done a lot of work on the surface treatment process of cable tray. For example, in the galvanizing process, after pickling, alkali washing, water washing, passivation, plating and re passivation, a layer of high-quality passivation film is formed on the inner layer and surface of the galvanized layer, and its corrosion resistance can be increased by 5 ~ 8 times. In particular, the improvement of the hot-dip galvanizing process makes the surface quality of the hot-dip galvanizing bridge meet the advanced standards of the United States, Canada and other countries, and its service life in coastal areas can exceed 10 years In 40 years.
