Wire mesh cable tray is a product that is being used a lot in small and medium projects, factories, indoor or outdoor cable systems. What is special about this product compared to other cable tray products that have so many applications? If you do not know the outstanding advantages and benefits that it brings, Bestray will help you find the answer through the article below.
1. What is a wire mesh cable tray?
The wire mesh cable tray is a mesh cable tray made from wire steel material, welded into blisters with the mesh size of 50mm x 100mm. It is used to provide support for data cables. In addition, the product helps with proper cable management, and cables are concentrated in neat, tidy places.
They used usually have many small cables. The product is made up of solid steel, clad steel, also known as wire steel. Therefore, the mesh trough can avoid corrosion caused by exposure to the surrounding environment. When installing wire mesh cable trays, it is almost only installed for some outdoor power lines.
2. Why use a wire mesh cable tray?
Wire mesh cable trays are gradually replacing traditional cable trays. Bestray will help you better understand the great advantages that the product brings:
- Easy to install and compact: Mesh cable trays are usually lighter in weight than traditional electrical cable trays, so when installed evenly easily and without too much human cost. However, after a period of use, it is necessary to regularly clean the electrical wires.
- Helps ventilation and cooling: When using common cable trays in data centers, factories, where there are many electronic devices and wires, the temperature will increase. Therefore, it is necessary to have an air conditioning system to reduce the heat. In particular, the mesh trough is the right choice to help the air conditioning system work quickly and efficiently and help balance the humidity and temperature better.
- Durability: the material used to make the mesh trough is round steel (wire steel) with a diameter of 5mm, so the product ensures durability over time.
- Convenience: During the construction or installation of the mesh trough system, the operation is also easier, it is possible to change the direction and orientation of the product without using many accessories such as cable trays. traditional.
In addition, the grid cable tray system is commonly used in the installation of electrical cables and wires in buildings, buildings, apartments, industrial parks, factories,... On the other hand, the trough system Mesh cables are also applied in the installation and protection of power distribution cables or communication signal cables.
Sometimes, you can also see the grating is also used to support the pipes to increase aesthetics and save living space. The product structure is flexible, easy to use and install, so it is especially useful in the case of changing a wiring system.
3. Types of wire mesh cable tray
3.1. Steel grating, powder-coated
Powder-coated grating is usually installed for works in factories and installed indoors (indoor use). The wire mesh cable tray with tray is made from round steel and painted with an external electrostatic coating to protect the product from corrosion.
3.2. Steel grating, pre-galvanized
Pre-galvanized is a mesh trough after processing with black wire steel, they will be processed by electroplating to create an outer layer of zinc with a thickness of >= 12µm to prevent corrosion. trail. The galvanized grating is used for indoor installation.
3.3. Steel grating, hot-dip galvanized
The hot-dip galvanized wire mesh cable tray is made of a very strong, shiny, and impact-resistant steel alloy. The device is dipped in a layer of hot zinc and has a rough grip on the surface. Therefore, a hot-dip galvanized mesh tray is often installed in outdoor constructions such as telecommunications stations, data stations, environments where metal is susceptible to corrosive effects and rust. These are places with harsh environmental conditions where the product is durable over time.
3.4. Stainless steel wire mesh cable trays (stainless steel 304/304L)
The SUS304 wire mesh tray is often installed for outdoor works such as food factories, data stations, telecommunications works. The equipment is made of stainless steel, so it is often used where working conditions are affected by environmental factors. When using 304 stainless steel mesh cable trays in this environment, will limit metal corrosion, rust and ensure a solid and sustainable product structure over time.
3.5. Stainless steel wire mesh cable trays (stainless steel 316/316L)
The SUS316 wire mesh cable tray has a simple structure with 3m length bars, so it is easy to carry and move at the construction site. Therefore, when constructing 316 stainless steel mesh cable trays, it is very simple, just need to cut steel pliers, screwdriver to turn nuts, it can be installed quickly, helping to reduce construction time.
One of the outstanding advantages of 304 and 316 stainless steel mesh troughs is the high corrosion resistance and heavyweight resistance. Thanks to the stable connection of the welds and durable stainless steel fibers.
