What are the specifications and models of the bridge?

The ** of the trough bridge is about dozens of yuan per meter, and the cheap one is more than ten or twenty yuan. The best of trough bridge is affected by many aspects, such as brand, category, specification, market, etc. The key is to learn how to choose.

1. When the cable network that needs to be shielded from electrical interference or has the requirements of protecting the external (such as: corrosive liquid, combustible dust and other environments), the trough composite anti-corrosion shielded cable tray (with cover) should be selected. The same material should be used for the bracket and bracket to improve the service life of the tray and accessories, and the cable tray should be covered in the environment or outdoor places that are easy to accumulate dust and other needs to be covered.

3. In addition to the above conditions, tray type, trough type, stepped type, glass anti-corrosion and flame retardant can be selected according to the environmental and technical requirements of the site

At present, cable trays are widely used in the construction industry, mainly trough bridges, ladder bridges, pallet bridges, etc.

The cable tray can be made in various widths, depths, wire diameters and different surface treatments according to the actual use requirements of the purchaser.

Cable tray width: from 50mm to 600mm; Special specifications can be customized.

Cable tray length: from 2000mm to 3000mm; Special specifications can be customized.

Cable tray height: 50mm, 100mm, 150mm, 200mm, 300mm, 400mm and 500mm special specifications can be customized.

Cable tray wire diameter: from 4mm 6mm; Special specifications can be customized.

Surface treatment of cable tray: electro-galvanized, hot-dip galvanized, sprayed, fireproof.

The cable tray is made of galvanized, aluminum alloy, 304 stainless steel.

The type of cable tray mainly depends on the weight of the cable and the use environment and other factors, and the following provides us with some commonly used types of cable trays on the market as a reference:

Trough cable trays: Trough cable trays are hermetically sealed trays, box-like shapes, and are used to lay cables.

Ladder cable tray: It looks like a ladder shape together, and the center is welded with a crossbar to reinforce the support, which makes it light weight, low cost, extremely strong bearing capacity and good air permeability.

Tray cable tray: Tray-type cable tray is a semi-sealed cable tray, which is very similar to the posture of the trough cable tray, and he has holes at the bottom for heat dissipation.

The following is an introduction to the commonly used standard ginseng on the market for inspection:

The standard is suitable for: trough tray (C), ladder tray (T), tray tray (P) (special standards can be customized by contact).

Thickness: non-standard) national standard).

Usually the models of cable tray are divided into: trough type, tray type, ladder type. The different materials of the cable tray are divided into: galvanized tray, stainless steel 304 tray, aluminum alloy 1060 tray, and the surface treatment process is divided into: fireproof baking paint, electrostatic spraying, and hot-dip galvanizing (hot-dip galvanizing).

Common specifications are: (width * height * thickness is: national standard thickness) 300mm*100mm* 400mm*100mm* 500mm*100mm* 600mm*200mm* 800mm*200mm* 1000mm*150mm* 1200mm*200mm* and so on.
