Hot-dip Galvanized Channel Cable Tray

Process introduction:

Galvanizing is an exemplary method of coating steel that provides extremely effective protection. The zinc is melted and applied to the steel in a liquid state. Its physical and chemical interactions create a pure zinc layer on top of the steel as well as a Zn-Fe alloy layer. This process has similar corrosion-resistance properties as electro-galvanizing, but it also has the added strength of the Zn-Fe alloy layer. As a result, it can withstand corrosion in even the harshest of environments, including strong acid, alkali, and fog. Its outstanding characteristics make it an excellent choice for a broad range of applications.

The hot-dip galvanized cable tray has become a popular choice due to its exceptional resistance to corrosion, which is essential for outdoor environments where atmospheric corrosion is a common issue. Compared to regular cable trays, it has a longer lifespan, offering greater durability. Its high degree of industrialization also makes it a reliable and stable option with consistent quality. Additionally, it requires minimal maintenance, making it an ideal solution for areas that are difficult to access. Overall, the hot-dip galvanized cable tray is a robust and reliable solution for serious atmospheric corrosion environments that require long-lasting service life.

(2) The steel surface is protected by a dense and thick layer of pure zinc, effectively preventing the steel matrix from coming into contact with corrosive substances. This layer of zinc shields the steel from corrosion, ensuring its longevity and durability. In addition, the zinc layer creates a thin and tightly-bound zinc oxide layer in the atmosphere which prevents water from dissolving it. This makes it all the more effective in preserving the steel matrix. If zinc oxide is unable to dissolve with other atmospheric elements, it will enhance its resistance to corrosion.

The combination of iron zinc alloy layer and compact structure gives it exceptional corrosion resistance in marine salt spray and industrial atmospheres. Its unique ability to withstand harsh environments makes it a reliable choice for various applications.

The strong wear resistance of zinc and iron is attributed to their firm combination and mutual solubility.

The ductility of zinc, coupled with the strong adhesion of its alloy layer to the steel base, allows for cold stamping, rolling, wire drawing, and bending of hot-dip plated parts without compromising the integrity of the coating. This means that manufacturers can form plated parts to their desired specifications without damaging the zinc layer.

The process of hot-dip galvanizing steel structures provides a similar effect as annealing treatment, resulting in enhanced mechanical properties of the steel. This treatment eliminates any stress that may have been present during the formation and welding of the steel, ultimately facilitating the transformation of the steel structure.

Hot-dip galvanized parts exhibit a gleaming and attractive surface finish.

(7) The most flexible zinc layer in hot-dip galvanizing is the pure zinc layer. It closely resembles pure zinc in terms of properties and exhibits ductility, making it highly flexible in nature.
