What is the difference between hot dip galvanized cable tray and galvanized cable 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 impregnated with a layer of hot plating.

Zinc, manufactured.

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. Hot-dip galvanizing, of course.

The cost of the bridge is higher. <>

It is the difference in the production process.

1. The main production process is different, hot-dip galvanizing is passed through the zinc pot solution, and electro-galvanizing is obtained by electrode reaction.

2. The anti-rust effect of electro-galvanizing applied to steel structures is generally not very good, mainly because the amount of galvanization is not reached, and the galvanization is uneven, and the rust phenomenon generally occurs in two or three years, and the poor quality is rusted after being exposed to the humid environment for more than ten days.

3. The process of cold galvanizing: the surface of the steel is chemically cleaned and put into the electroplating solution, which contains zinc oxide. One pole of direct current is connected to steel, and the other pole is connected to the zinc plate in the electroplating solution.

When energized, the zinc is replaced to the surface of the steel in a molecular state. If it is passivated with brightener, it will reflect the cloud-like bright coating.

4. Process of hot-dip galvanizing: the process and method of immersing steel or castings in molten zinc liquid to form zinc-iron alloy or zinc and zinc-ferroalloy overlay on its surface.

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

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). The hot-dip galvanized coating is thicker and has strong corrosion resistance.

Hello, I am inquiring for you here, please wait a while, I will reply to you immediately 2. The anti-rust effect of electro-galvanizing applied to steel structures is generally not very good, mainly because the amount of galvanization is not reached, and the galvanization is uneven, and there is rust in two or three years, and the poor quality is rusted after being exposed to the humid environment for more than ten days.

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

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.

Changpeng tray: hot-dip galvanized cable tray and cold-dip galvanized cable tray have the following four differences:

1. The main reason is that the production process is different, the hot-dip galvanized bridge is passed through the zinc pot solution, and the cold-dip galvanized bridge is obtained by electrode reaction.

2. The anti-rust effect of the electro-galvanized bridge applied to the steel structure is generally not very good, mainly because the amount of galvanization is not reached, and the galvanization is uneven, and the rust phenomenon generally occurs in two or three years, and the poor quality is exposed to the humid environment for more than ten days and rusts.

3. The process of cold galvanized cable tray: the surface of the steel is chemically cleaned and put into the electroplating solution, which contains zinc oxide. One pole of direct current is connected to steel, and the other pole is connected to the zinc plate in the electroplating solution.

When energized, the zinc is replaced to the surface of the steel in a molecular state. If it is passivated with brightener, it will reflect the cloud-like bright coating.

4. Process of hot-dip galvanized cable tray: the process and method of immersing steel or castings in molten zinc liquid to form zinc-ferroalloy or zinc-zinc-ferroalloy covering layer on its surface.

5. Changpeng hot-dip galvanized bridge has a thick coating and strong corrosion resistance. The galvanized layer of cold galvanized bridge is brighter than that of hot plating, but it is thinner and has weak rust resistance. Generally, the cold-dip galvanized bridge is processed into a bridge with hot-dip galvanized sheet, while the hot-dip galvanized bridge is processed by cold-rolled sheet and then hot-dip galvanized.

The anti-rust effect of electro-galvanizing applied to steel structures is generally not very good, mainly because the amount of galvanization is not reached, and the galvanization is uneven, and there is rust in two or three years, and the poor quality is rusted after being exposed to the humid environment for more than ten days.

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

Hot-dip galvanizing is also known as "hot-dip galvanizing", and galvanizing is also ("cold galvanizing" and "electro-galvanizing").

Compared with cold-dip galvanizing, the hot-dip zinc layer has better corrosion resistance due to the ZN-Fe alloy layer. In general, the zinc layer of hot-dip galvanized is thicker and the corrosion resistance is better.

The zinc layer of electro-galvanized is thinner and has poor corrosion resistance.

Look at the name also know, there is a layer of fireproof material outside the fireproof bridge, non-combusting, galvanized will not reach this point, installation, fireproof bridge must have jumper wires, hot-dip galvanized do not use.

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.

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).

Process of hot-dip galvanizing: the process and method of immersing grinding steel or castings in molten zinc liquid to form zinc-ferroalloy or zinc-zinc-ferroalloy overlay on its surface.

Galvanized cable tray is generally used indoors, because galvanized cable tray is galvanized iron after all, which will rust when exposed to water, and must not be in a highly corrosive environment.

Installation. The hot-dip galvanized trunking tray has very good anti-corrosion performance, long durability, much longer life than ordinary tray, high degree of production industrialization, and stable quality, so it is generally used outdoors. Mainly for rust prevention. Also pay attention to the accessories, screws, connecting pieces and so on.

It is also hot-dip galvanized, preferably stainless steel.
