Introduction of hot-dip galvanized cable tray.

At present, cold galvanizing (electro-galvanizing) is only used on a small number of accessory products, and few main material products are cold-galvanized. Now the leakage hot-dip galvanized strip produced by the steel mill is actually hot-dip galvanized, just to distinguish it from the subsequent product galvanizing, which is called hot-dip galvanized sheet hot-dip galvanized steel strip. The galvanizing of steel products in the corner groove is basically hot-dip galvanized, and the line pipe, bridge and bracket products are made of hot-dip galvanized sheet, and the products with high anti-corrosion requirements can also be hot-dip galvanized.

In the bidding technical documents, it is necessary to distinguish these galvanizing processes to avoid unnecessary trouble in the later stage.

Hot-dip galvanizing is also known as "hot-dip galvanizing", hot-dip galvanizing is a good kind of coating process for various protective steel structures, hot-dip galvanized cable tray is to remove rust from the bridge, soaked in the high-temperature zinc pool, after complex physical and chemical action, not only on the surface of the cable tray plated with a thick pure zinc layer, but also to form a zinc-iron alloy layer. The hot-dip galvanized surface treatment not only has the characteristics of electro-galvanized corrosion resistance, but also contains a zinc-iron alloy layer. It also has strong corrosion resistance, which is incomparable with ordinary electrogalvanized cable trays.

Therefore, hot-dip galvanizing surface treatment is especially suitable for use in various strong acid-alkali mist and other strong corrosive environments.

Example diagram of fireproof bridge elbow:

1. There is only one model of bridge reducer: trough reducer. When the bridge is to pass through the wall or cabinet, the hole is not so big and cannot be penetrated, it can be connected with a reducer, and the size of the line can be controlled at the same time.

2. The bridge tee is divided into two types: horizontal tee and vertical tee. Models are divided into: trough type cross, tray type cross, ladder type cross.

3. Bridge tee is divided into 3 types: horizontal tee, vertical tee, and reducer tee. The model return is divided into: trough tee, tray tee, ladder tee.

4. The bridge elbow is usually divided into three types: horizontal bending, vertical bending, and "zigzag" bending, which are divided into two ports, and the size of the two connecting ports is the same width and height. Models are divided into: trough elbow, tray elbow, ladder elbow.

Hot-dip galvanized tray.

Now there are only a few electro-galvanized (cold galvanized pin cavity) processes used on the bridge accessories products, and the hot-dip galvanized strip produced by the steel plate factory is actually hot-dip galvanized, in order to better distinguish the thickness of the galvanized zinc layer with the follow-up products, it is called hot-dip galvanized sheet hot-dip galvanized steel strip. The galvanizing of U angle groove steel products is basically hot-dip galvanized. Wire pipes, bridges, brackets and products are made of hot-dip galvanized sheets, and some projects with high anti-corrosion requirements can also be hot-dip galvanized, which can reach a thickness of about 50 microns.

Electro-galvanized (cold-galvanized) tray.

Electrogalvanizing is a process that uses electrolysis equipment, and the bridge is dusted, oiled, and pickled. It is then placed in a solution consisting of zinc salts. The dispensing device is energized and the electrodes are moved in a directional direction from the positive to the negative electrode.

A thin layer of zinc is deposited on the bridge. The finished workpiece is full of color and smooth surface. However, there is only a few microns of zinc layer, which is only used for temporary corrosion.

Due to the poor anti-corrosion effect and environmental pollution, the electro-galvanizing process is now only applicable to some bridge accessories.

Hot-dip galvanized tray.

Hot-dip galvanized sheet Hot-dip galvanized steel strip is made of shirts, and the zinc layer is about 11 microns.

Hot-dip galvanized ladder bridge is made of electro-galvanized ladder bridge, which is also known as hot-dip galvanizing industry"

Hot-dip galvanizing"The finished electrogalvanized ladder bridge is put into the zinc liquid at 600 °C to make the surface of the steel structure covered with a hot-dip galvanized layer, which plays a targeted role in anti-corrosion, and the structural bearing capacity of the ladder bridge itself is more than that of the "trough type".

With the development of science and technology, the protection requirements for steel are getting higher and higher, and the demand for hot-dip galvanizing capacity continues to increase.

The hot-dip galvanized ladder bridge does not have the fire performance of the fireproof bridge, and the fireproof cable tray is purchased if the bridge has fire protection requirements. The hot-dip galvanized ladder bridge is not sealed like the trough bridge, but it has extremely strong bearing capacity and good air permeability. (A slot cover can be installed to prevent dust).

The hot-dip galvanized cascade cable tray is specified as follows:

The cascade hot-dip galvanized cable tray can be recognized by everyone, indicating that it has unique advantages, first of all, the main thing is that it has good corrosion resistance, long service life, stable quality and high degree of production industrialization. Therefore, it is more widely used in places with large corrosive environments.

Cascade bridge stands out in many kinds of bridge, is designed by the lack of special or industry people in combination with domestic and foreign data on continuous improvement, it has light weight, low cost, unique shape, easy installation, heat dissipation, good ventilation and other characteristics are the needs of the public. In the laying of cables with large diameters, he is more suitable for the laying of high-voltage and low-voltage power cables. The setting of galvanized anti-corrosion materials adds a different color to the cable tray and brings new business opportunities to the cable tray industry.

A cable is made of one or more conductors that are insulated from each other and an outer insulating protective layer that transmits electricity or information from one place to another. A yard is usually a rope-like cable made up of several or groups of wires (at least two in each group), each of which is insulated from each other and is often twisted around a center, with a highly insulating covering over the entire outskirt. The cable has the characteristics of internal energizing and external insulation.

Zinc

Zinc (zinc) is a chemical element, its chemical symbol is Zn, its atomic number is 30, its relative atomic mass is, it is a light gray transition metal.
