1, cable tray hot dip galvanizing and hot dip zinc difference hot dip galvanizing is the cable tray surface coated with a layer of zinc, through electrolysis will be adhered to the zinc on the surface of the bridge, forming a layer of zinc. Hot dip galvanizing is the cable tray immersed in molten zinc liquid, so that the bridge surface covered with a layer of uniform thickness, dense zinc layer. The thickness of the zinc layer of hot-dip galvanizing is generally between 5-15μm, while the thickness of the zinc layer of hot-dip zinc is generally between 45-100μm, so hot-dip galvanizing has better anti-corrosion performance. Hot-dip galvanizing has a higher surface finish than hot-dip zinc, but hot-dip zinc has a more even and flat surface. Hot-dip galvanizing is suitable for occasions with high requirements for surface flatness and less stringent requirements for corrosion resistance, such as hooks on the exterior walls of buildings and automobile parts, etc. Hot-dip zinc is suitable for occasions with high requirements for corrosion resistance, such as marine engineering and chemical equipment. In short, hot dip galvanizing and hot dip zinc have their own advantages and disadvantages, the specific choice should be based on the use of the environment and requirements for comprehensive consideration. 2, cable tray hot dip galvanizing and spraying the difference between hot dip galvanizing and spraying cable tray and spraying are designed to prevent corrosion and prolong the service life, but the difference is that: hot dip galvanizing is a cable tray immersed in hot dip galvanizing pool, the surface of the formation of a layer of zinc. And plastic spraying is the paint sprayed on the surface of the cable tray to form a protective layer. Hot-dip galvanized corrosion resistance is better, can be used in harsh environments for a longer period of time. The corrosion resistance of plastic spraying is slightly inferior, but it is more beautiful in appearance. Hot-dip galvanizing requires more cost and time, but provides longer-lasting protection. In contrast, spray molding is cheaper and faster, but requires regular inspection and maintenance. Therefore, when choosing the material and treatment of cable tray, it is necessary to make comprehensive consideration according to the specific use environment, requirements and economic strength.
