Combined cable tray is a new kind of bridge, it is the second generation products of series of cable tray, and it is suitable for installing each unit of different projects and all kinds of cable. There are some advantages of simple structure, flexible configuration, convenient to install, new forms and so on.
There are three basic cable trays with the width of 100mm, 150mm and 200mm of the cable tray which can installed to be the one, then equipped with the cable tray roll forming machine you need. It doesn’t need to produce fittings such as bending, and then can according to the requirements at present. There should not need to punch in any place can be out by the tube after welding. It is convenient for engineering design and transportation, also convenient for installation. It is the most ideal products of cable tray nowadays.
The cable tray of FRP pultrusion bridge uses unsaturated polyester resin and alkali roving through heating mould drawing process, which with the advantages of elegant appearance, structure compact, anti-corrosion and so on. Lights stabilizer and fire retardant are added into resin to improve the anti-aging properties and flame retardant prosperities of cable tray of roll forming machine. And the oxygen index should be equal or greater than 32; the width of the bridge should be assembled modular over 400.
Large span cable tray is a general bridge with large support span, and the structure design is exquisite so that with the capacity can load more than other kinds of cable tray, then easily installed with the cable tray roll forming machine, and it is not only suitable for equipping the cable of oil refining industry, chemical industry, textile, machinery, electric power and so on outside. Also it can be used for the works under ground, for example, the subway and civil air-defense construction. Large span cable tray includes large span stair, tray, heavy load, corresponding types of fittings and so on.
There is a cover plate of large span cable tray, if you need it, you should tell to the seller when you place an order, or buy it according to the type of the cover plate.

It is suitable for controlled cable of laying computer, communication cable and other system with high sensitivity, and it is useful to the effect of the shielding interference and protection of cable in heavy corrosion environment. The protective cover of groove type cable tray is commonly used with machine supply; other accessories are used with stair and tray.
