Is the cable tray hot dip galvanized expensive or fireproof expensive

The fireproof bridge mainly plays the flame retardant performance, while the hot-dip galvanized bridge is mainly anti-corrosion and long life.

The hot-dip galvanized tray is more expensive than the fireproof tray.

Therefore, the hot-dip galvanized bridge is expensive, and the hot-dip galvanized bridge is also known as the "hot-dip galvanized bridge", because the hot-dip galvanizing process is more complicated, and it is also expensive, but the anti-corrosion performance of the hot-dip galvanized bridge is not comparable to the fireproof bridge.

The function of fireproof bridge: The fireproof bridge is to spray a layer of fireproof paint on the surface of the ordinary bridge to play the role of fireproof and flame retardant. In fact, the bridge itself will not catch fire, it may only be the cable, and the fireproof paint plays a fireproof and flame-retardant principle.

Galvanized bridge is mainly used in humid and corrosive environments. According to the different production processes, it is divided into hot-dip galvanizing and electro-galvanizing (i.e., cold galvanizing).

How can the two properties be compared, it is best to consider hot-dip galvanizing. There are only fire-resistant bridges, no fireproof bridges.

You have to describe the requirements clearly. You can find Jiangsu Greenmel Electric for consultation**.

Performance Characteristics Differences:

1.The anti-corrosion, anti-rust, anti-acid and alkali properties of the galvanized cable tray are very good, and they are very good in the environment with heavy corrosion, acid and alkali, etc., which can well protect the cable line from corrosion damage.

2.The fireproof cable tray is an upgraded version of the galvanized cable tray, which is processed by a process on the surface of the galvanized cable tray, which not only has the performance characteristics of anti-corrosion, anti-rust, anti-acid and alkali, but also has good performance characteristics of fire prevention, heat insulation and flame retardant.

Differences in use: 1Galvanized cable tray can be applied in wet, corrosive, acid-alkali and other environments. Moreover, galvanized cable tray can also be divided into two galvanizing processes: hot-dip galvanizing and cold-dip galvanizing.

2.The fireproof cable tray can be used for the laying and installation of indoor cable lines such as cable lines below 10 thousand volts, control cables, lighting wiring, etc.

Differences in treatment process:

1.Galvanizing process is a good process method to protect steel, galvanized cable tray is to soak the steel cable tray after rust removal into a high temperature zinc liquid of about 600 degrees Celsius, so that the surface of the steel cable tray is attached to a thin layer of zinc, the thickness of the zinc layer is about 5mm, so that the steel cable tray plays an anti-corrosion effect.

2.The fireproof cable tray is made of spraying fireproof materials on its surface, which is mainly composed of glass fiber reinforced materials, inorganic adhesive composite fireproof boards, metal skeletons and other fireproof substrates. The fireproof cable tray can play a good role in blocking the spread of fire when encountering fire and high temperature, so it has a very good effect of fire prevention and fire resistance, and also has the characteristics of fire resistance, oil resistance, corrosion resistance, non-toxic, no pollution, and convenient overall installation.

Galvanized cable tray also has a little fireproof function, but compared with the special fireproof tray is still a little inferior, we all in the purchase, to understand their needs, and then choose the right cable tray, but also to distinguish the difference between the cable tray, so that the use will be long.

These should be two products.

Hot-dip galvanizing is generally a pipe, that is, a galvanized pipe.

In order to improve the corrosion resistance of steel pipes, galvanized general steel pipes. Galvanized steel pipes are divided into hot-dip galvanizing and electro-galvanizing, hot-dip galvanizing has a thick galvanized layer, low electro-galvanizing cost, and the surface is not very smooth. Blowing oxygen welded pipe:

It is used as a pipe for blowing oxygen in steelmaking, generally with small-diameter welded steel pipes, and the specifications are 8 8-2 inches. It is made of steel strip or 195-Q235, and it has to be aluminized in order to prevent corrosion.

Cable tray: the weak current system of intelligent buildings, usually composed of multiple information monitoring and communication facilities such as BA (building automation), OA (office automation), CA (communication automation) and other corresponding systems, cable tray is divided into trough type, tray type and ladder frame type and other structures, which are composed of brackets, brackets and installation accessories. When selecting, attention should be paid to whether all parts of the bridge meet the requirements of serialization, generalization and standardization.

The bridge frame in the building can be erected independently, and can also be attached to various buildings (structures) and pipe gallery supports, which should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance, all parts need to be galvanized, and the bridge is installed in the open air outside the building, if it is near the sea or belongs to the corrosion area, the material must have anti-corrosion and moisture resistance.

1. Durable: In the suburban environment, the standard hot-dip galvanized anti-rust thickness can be maintained for more than 50 years without repair; In urban areas or offshore areas, the standard hot-dip galvanized anti-rust layer can be maintained for 20 years without repair; 2. Good reliability: the galvanized layer is metallurgically combined with the steel and becomes a part of the steel surface, so the durability of the plating layer is more reliable; 3. The toughness of the coating is strong

The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use; 4. Comprehensive protection: every part of the plated parts can be coated with zinc, even in the depressions, sharp corners and hidden places can be fully protected; 5. Time-saving and labor-saving: the galvanizing process is faster than other coating construction methods, and can avoid the time required for painting on the construction site after installation; 6. Corrosion resistance

Hot-dip galvanizing is generally carried out in accordance with BS EN ISO 1461, which limits the minimum thickness of the zinc layer, so its rust protection period and performance are reliable and predictable.

Cable tray is used to support cables and protect cables, which has brought a lot of convenience to our lives, such as some large power plants and substations, etc., are used to cable trays. Even the high-rise buildings we usually live in use cable trays. Let's take a look at the uses of galvanized cable trays.

Uses of galvanized cable trays.

The galvanized cable tray mainly has anti-corrosion performance and the coating on the surface makes the cable tray more beautiful, the choice of color can be matched with the interior design sense of beauty, and the galvanized cable tray can be installed outdoors.

Cable tray is also divided into two types of indoor and outdoor use, outdoor use of cable tray, cable tray must ensure that there is good compressive capacity and corrosion resistance, after all, long time outdoors dust, air and other factors will affect the life of cable tray, if you can not ensure the quality, it is easy to affect the later use of cables, and even to maintain frequently. The galvanized cable tray itself has good corrosion resistance and excellent performance, which is suitable for outdoor use.

In fact, cable trays are often used in buildings, so that cable trays need to support cables, and galvanized cable trays play such a role. General residences or shopping malls, etc., will also use such cable trays, which are easy to install, and have a long service life, which can also effectively avoid the occurrence of danger. However, the bridge used in the building must pay attention to aesthetics and safety, and pay equal attention to ensure practicality.

Hello, I am glad to answer for you: polymer cable tray and hot-dip galvanized cable tray are two different cable tray materials. The polymer cable tray is made of polymer materials, which has the characteristics of excellent corrosion resistance, aging resistance and wear resistance, so the price is relatively high.

The hot-dip galvanized cable tray is made of zinc alloy material, and the surface treatment is carried out by the hot-dip galvanizing process, which can play an anti-corrosion role, which is relatively low. Specifically, because of the particularity of materials and processes, polymer cable trays usually range from tens of yuan to hundreds of yuan per meter. The hot-dip galvanized cable tray is different according to the specifications, thickness and other factors, between more than ten yuan and dozens of yuan per meter.

Therefore, from the point of view, hot-dip galvanized cable tray is relatively cheap, but it is inferior to polymer cable tray in terms of anti-corrosion performance. When choosing a cable tray, you need to consider it comprehensively according to factors such as actual needs and budget.

The hot-dip galvanized cable tray is the "hot-dip galvanized tray", and the ordinary galvanized cable tray is also the "electro-galvanized tray, cold galvanized tray".

The galvanized bridge is made of "cold galvanized sheet", while the hot dip galvanized bridge is made of cold galvanized bridge through surface treatment and a layer of hot-dip galvanized by surface treatment.

The anti-corrosion ability of the cold-dip galvanized bridge is poor, while the anti-corrosion ability of the hot-dip galvanized bridge is better.

The life of hot-dip galvanized bridge is longer than that of galvanized bridge, and hot-dip galvanizing has an absolute advantage in terms of hardness and impact resistance. Of course, the cost of hot-dip galvanized bridge is higher.

Usually the hot-dip galvanized cable tray refers to the hot-dip galvanized cable tray, and the small-sized metal trunking is the cable tray.

However, the material report of the galvanized sheet cable tray is "hot-dip galvanized coil".

1. Application range of hot cable galvanizing:

Because the performance of the hot-dip galvanizing process is very good, it has a very wide range of applications in various fields. For example, the hot-dip galvanizing process is used in industrial fields (such as chemical equipment, petroleum processing, marine exploration, metal structures, power transmission, shipbuilding, etc.), agricultural fields (such as: sprinkler irrigation, ambiguous houses), construction (such as:

In recent years, water and gas transmission, wire casing, scaffolding, housing, etc.), bridges, transportation, etc., have been widely used. Due to the characteristics of beautiful appearance and good corrosion resistance, hot-dip galvanized products are more and more widely used.

Second, the application range of cable galvanizing:

With the development of domestic economy and technology, more and more industries are involved in the electrogalvanizing process. At present, the use of electrogalvanizing in the market has spread all over the major fields, such as machine manufacturing, electronics, precision instruments, chemical industry, light industry, cable tray, transportation, aerospace, atomic energy, etc., which is of great significance to the development of modern society.

The hot-dip galvanized bridge is made of electro-galvanized bridge through high-temperature wheel processing, which plays a role in the pure anti-corrosion of the wax ruler, and now the country's requirements for steel are becoming more and more stringent, so major projects are using hot-dip galvanized bridge, and the safety is greatly improved.

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, dip the skin and bubble under 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 cannot be compared with ordinary galvanized cable trays.

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

1. The difference between electro-galvanized bridge and hot-dip galvanized bridge.

1.The principle of the two is different: electrogalvanizing, also known as cold galvanizing, is to attach a galvanized layer to the surface of steel by electrochemical methods;

2.The appearance of the two is different: the appearance of electro-galvanized is relatively smooth and bright, and the electroplating layer with color passivation process is also yellow-green as the main color, which is colorful.

The appearance of hot-dip galvanizing is slightly rougher than that of electro-galvanizing, silvery-white, and the appearance is prone to process water lines, especially at one end of the workpiece.

3.The thickness of the two is different: the zinc layer of electro-galvanized is relatively thin, only about 3-5 m thick, although the surface is smooth, but there will be gray and dirty performance, and the processing performance of jujube is good and the corrosion resistance is insufficient.

The hot-dip galvanized zinc layer itself is relatively thick, generally with a thickness of more than 65 m, so it has a good anti-corrosion ability, although the surface is bright, but the pure talk is slightly rough, and there may be zinc sparks.

Electro-galvanized bridge is suitable for indoor dry environment; The hot-dip galvanized tray is suitable for outdoor or corrosive environments.

2. Characteristics of electro-galvanized bridge: The purpose of electro-galvanizing is to prevent steel objects from being corroded, improve the corrosion resistance and service life of steel, and also increase the decorative appearance of the product. The amount of steel corroded in China accounts for almost one-tenth of the entire amount of steel every year, so in order to protect the service life of steel or its parts, electrogalvanizing is generally used to process steel.

The characteristics of hot-dip galvanized bridge: excellent anti-corrosion performance, long service life, much longer life than ordinary bridge, high degree of production industrialization, stable quality. Therefore, it is widely used in outdoor environments that are severely corroded by the atmosphere and difficult to maintain.
