When choosing the galvanizing method for cable trays, hot-dip galvanizing is considered a better choice. The following is a comparative explanation of hot galvanizing and cold galvanizing for Jinan cable trays:
Introduction to Cold Galvanized Cable Tray:
Cold galvanizing, also known as "electro galvanizing", is directly produced using the cold galvanizing process. The principle of the cold galvanizing process is to obtain it through electrode reactions. The corrosion resistance of cold galvanizing is definitely not as good as other materials of cable trays, mainly because its galvanizing amount is not enough, so it is often installed indoors in a dry environment.
Introduction to hot-dip galvanized cable tray:
Hot dip galvanizing, also known as "hot dip galvanizing", is the process of removing rust from the cable tray and placing it in a high-temperature molten zinc solution at around 600 ° C, so that a thick zinc coating is adhered to the surface of the cable tray. According to national standards, the zinc coating thickness of thin steel plates below 5mm should not be less than 65um, and on thick steel plates should not be less than 86um, which can effectively achieve the goal of corrosion prevention. As an effective method of metal corrosion prevention, Hot-dip galvanization technology has been widely used in metal equipment of various industrial structures, and its corrosion resistance life can reach more than 10 years.
1. Hot dip galvanizing: Hot dip galvanizing is the process of immersing steel materials into molten zinc for galvanizing. This process creates a dense and uniform zinc layer, providing excellent corrosion resistance and durability. The coating thickness of hot-dip galvanizing is usually thicker than that of cold galvanizing, thus providing better protection for steel.
2. Cold galvanizing: Cold galvanizing is the process of using the electroplating process to produce a uniform, dense, and well bonded metal or alloy deposit layer on the surface of the workpiece through electrolysis. The zinc layer of cold galvanizing is relatively thin and may not provide the same corrosion resistance and durability as hot galvanizing.
Overall, hot-dip galvanizing is generally considered a better method of galvanizing, especially in cable tray applications exposed to harsh environmental conditions. Hot dip galvanizing can provide longer lasting protection against corrosion and wear.
However, the specific selection should be evaluated based on factors such as application requirements, cost, and feasibility. When selecting any type of galvanizing method, ensure compliance with relevant industry standards and specifications, and make the correct decision.
