Here are two ways to quickly identify a good cable tray:
1. according to the material: divided by the material, there are mainly steel, glass fiber reinforced plastic and aluminum alloy, glass fiber reinforced plastic cable tray is characterized by light weight, the proportion is only 1/4 of carbon steel; Good water resistance and erosion resistance, suitable for chemical plants, not easy to burn, refractory fiberglass cable bridge oxygen index ≥32, long service life, the general design life of 20 years.
2. Structure type: in the engineering design documents, the price of cable tray with different types and materials varies greatly, and the confusion of structure type will bring the problem of heat dissipation in the work site. According to the environmental characteristics and the needs of construction engineering, the reasonable choice of cable tray is made. In addition to the size of the manufacturer, in the purchase process to choose what kind of material cable bridge is appropriate.
