Hot-dip galvanized hot-dip galvanized bridge

Hot-dip galvanized cable tray and galvanized bridge tray are mainly the difference in manufacturing process.


1. Mainly due to different production processes, hot-dip galvanizing is passed in a zinc pot solution, and galvanizing is obtained through electrode reactions.


2. Electroplated zinc applied to steel structures is generally not very rust-proof, mainly because the amount of galvanization cannot be reached, and the galvanization is uneven. Generally, rust occurs in two or three years, and poor quality is exposed to humidity It rusted in the environment for more than ten days.

3. The process of cold galvanizing: the surface of the steel is chemically cleaned and put into a plating solution, which contains zinc oxide. One pole of the direct current is connected to steel, and one pole is connected to a zinc plate placed in a plating solution. After the current is applied, zinc is replaced on the surface of the steel in a molecular state. If the brightening agent is added to passivate, the bright cloud-like bright coating is reflected.


4. Hot-dip galvanizing process: The process and method of forming a zinc-iron alloy or zinc and zinc-iron alloy coating on the surface by immersing steel or casting in molten zinc solution.

The hot-dip galvanized coating is thick and has strong corrosion resistance. Cold galvanized galvanized layer is brighter than hot galvanized, but thinner and weaker rust resistance
