As a type of cable tray, the development of tray-type cable trays is closely related to the hot-dip galvanizing process and the overall development of my country's cable tray industry. Hot-dip galvanizing was invented around 1750 and has a history of over 250 years. The earliest introduction of hot-dip galvanizing technology to China was in 1972, when Wuhan Iron and Steel (WISCO) imported my country's first hot-dip galvanizing line for strip steel from Germany, which went into production in 1979. The production and application of cable trays also began with the introduction of this technology and equipment.
Over the past 40 years of reform and opening up, cable trays have developed rapidly in my country and have become an indispensable laying material for integrated cabling. Among them, hot-dip galvanized cable trays are widely used in many fields such as automobiles, construction, power, and transportation due to their excellent corrosion resistance, long service life, and production stability.
