Cable trays are divided into grooved cable trays, tray cable trays and step cable trays, grid trays and other structures, consisting of brackets, bracket arms and installation accessories. Can be set up independently, can also be laid in a variety of buildings (structures) and pipe corridors bracket, reflecting the structure is simple, beautiful modeling, flexible configuration and easy maintenance and so on. Numerous advantages, the use of bridges is becoming more and more widespread. In the weekday management, do a good job of anti-corrosion treatment need to pay attention to what aspects.

What are the anti-corrosion treatment methods for bridge?

1, cable tray, trunking and its support hangers used in corrosive environments, corrosion-resistant rigid materials should be used to manufacture, or take anti-corrosion treatment, anti-corrosion treatment should be engineering environment and durability requirements.

Cable tray

2, cable tray in the fire requirements of the section, can be added in the cable ladder frame, tray with fire-resistant or flame retardant properties of the board, net and other materials constitute a closed or semi-closed structure, and take the bridge and its support bracket surface painted with fire-resistant coatings and other measures.

3, in selecting the load of cable ladder frame, the working uniform load of cable bridge should not be greater than the rated uniform load of the selected cable bridge load, if the actual span of the support hanger of the cable bridge is not equal to 2m, then the working uniform load should be required.

4, components and support hangers in the corresponding load conditions, its specifications and dimensions should be matched with the tray, ladder frame straight section, bend through the series.

5, in the selection of cable tray bend through or lead on, lead off device, should not be less than the cable tray cable to the small allowable bending radius.
