In the project, the cable tray is a commonly used material facility for electrical installation. It is better than the pipeline because of the many cables laid and the construction is convenient. Especially in the system trunk line and the centralized wiring situation, its superiority is more reflected. There are many types of cable trays, such as trough type, tray type, ladder type and so on.

The cable tray also has many kinds of materials and different types of processes. For example, the materials are divided into stainless steel, aluminum alloy, glass fiber reinforced plastic, and other materials; the processes are divided into hot-dip galvanizing, electrostatic spraying, galvanizing, and other processes; Fire-resistant cable tray. The performance characteristics of each material and process are different.

The main purpose of the cable tray is to support the cable, protect the cable and manage the cable, which brings great convenience to our cable line management.

The difference between a galvanized cable tray and hot-dip galvanized cable tray 

Galvanized cable tray holder:

Galvanized cable tray is also known as an electro-galvanized cable tray; most people understand it as galvanized cable tray and think it is a hot-dip galvanized cable tray. In fact, it is wrong. Like galvanized pipe, there are two kinds of galvanizing of cable tray, namely cold galvanized (electro-galvanized) and hot-dip galvanizing (hot-dip galvanizing);

Steel can easily rust in air, water or soil, or even be completely damaged. The annual loss of steel due to corrosion accounts for about 1/10 of the entire steel output. On the other hand, in order to make the surface of steel products and parts have a certain special function, and at the same time give the surface a decorative appearance, electro-galvanized steel is generally used. way to deal with it.

✔️Application range:

With the development of scientific and technological production, the fields involved in the electroplating industry are more and more extensive. At present, the application of electrogalvanizing has spread to various production and research departments of the national economy. For example, machine manufacturing, electronics, precision instruments, chemical industry, light industry, transportation, weapons, aerospace, atomic energy, etc., have great significance in the national economy.

Hot dip galvanized cable tray：

Among various coating methods for protecting steel substrates, hot-dip galvanizing is a very good one. It is in the liquid state of zinc, after quite complex physical and chemical action, not only a thick pure zinc layer is plated on the steel, but also a zinc-iron alloy layer is formed. This kind of plating method not only has the corrosion resistance characteristics of electro-galvanizing, but also has a zinc-iron alloy layer. It also has strong corrosion resistance unmatched by electro-galvanizing. Therefore, this plating method is especially suitable for strong corrosive environments such as various strong acids and alkali mists.

✔️Application range:

The application of hot-dip galvanizing has also expanded with the development of industry and agriculture. Therefore, hot-dip galvanized products are used in industry (such as chemical equipment, petroleum processing, marine exploration, metal structures, power transmission, shipbuilding, etc.), agriculture (such as sprinkler irrigation, heating), construction (such as water and gas transmission, wire casings, etc.), scaffolding, houses, etc.), cable trays, transportation, etc., have been widely used in recent years. Because hot-dip galvanized products have the characteristics of beautiful appearance and good corrosion resistance, their application scope is more and more extensive.
