1. aluminum alloy: aluminum cable tray is extruded from aluminum alloy, with high dimensional accuracy, good strength, beautiful appearance, light weight and large bearing capacity. The surface of aluminum cable tray is treated by sandblasting oxidation to form a natural oxide protective film, which has strong corrosion resistance to atmosphere and chemical media.
2. Stainless steel: Stainless steel has four characteristics: high temperature resistance, moisture resistance, corrosion resistance and fire prevention, and its appearance can be smooth and dripping. If laid indoors, its service life can be longer.
3. Galvanized sheet: It has a thick and dense layer of pure zinc covering the steel surface, which can prevent the steel substrate from contacting with any corrosive solution and protect the steel substrate from corrosion. In general atmosphere, a thin and dense zinc oxide layer is formed on the surface of zinc layer, which is insoluble in water and plays a certain protective role on steel matrix. If zinc oxide reacts with other components in the atmosphere to form insoluble zinc salts, the anticorrosion effect is more ideal.
4. FRP: FRP cable tray has high mechanical strength, both the rigidity of metal tray and the toughness of FRP tray, good corrosion resistance and strong aging resistance. Can be widely used in petroleum, chemical industry, electric power, light industry, television, telecommunications and other aspects.
