Galvanized perforated cable tray, also known as gi perforated tray, is the most widely used type in petroleum, chemical, power, light industry, television, telecommunications, and other fields. The galvanized perforated cable tray has the advantages of light weight, large load capacity, beautiful appearance, simple structure, and convenient installation. It is suitable for both the installation of power cables and the laying of control cables.

The surface treatment of perforated cable tray can be divided into three types according to user needs: galvanizing, electrostatic spraying, and hot-dip galvanizing. Special anti-corrosion treatment can be applied in heavily corrosive environments.

Galvanized perforated cable trays can be equipped with protective covers, which can be specified when ordering. All accessories are compatible with stepped and trough type cable trays.

JLH Electric has owned hot dipped galvanized workshop itself. And we can well control the hot dipped galvanized quality, delivery time and production process. In this article, let’s explore the definition, benefits , application and how to custom galvanized perforated cable tray. It will help you to understand the this type of cable tray.

1.What Is galvanized perforated cable tray?

  • Galvanized perforated cable tray is a type of cable management system used to route and support electrical cables, wires, and other types of cabling.The tray is made from steel that has been coated with a layer of zinc through a process called galvanization. This provides corrosion resistance and enhances the durability of the tray.Galvanized perforated cable tray has a series of holes or perforations along its surface. This allows for improved airflow around the cables, which can help with heat dissipation. The perforations also reduce the overall weight of the tray.
  • The perforated design, combined with the galvanized steel construction, makes these cable trays a popular choice for applications where corrosion resistance, airflow, and cable management are important considerations.

2. What Are Benefits of galvanized perforated cable tray?

2.1 Corrosion Resistance

  • The galvanized coating protects the steel from rust and corrosion, increasing the tray’s lifespan in damp or humid environments.
  • This makes galvanized perforated cable tray suitable for use in both indoor and outdoor applications.

2.2 Improved Airflow

  • The perforations in the tray design allow for better airflow around the cables.
  • This enhanced airflow can help dissipate heat buildup, which is important for maintaining the integrity and performance of the cables.

2.3 Reduced Weight

  • The perforations reduce the overall weight of the cable tray compared to solid-bottom trays.
  • This makes galvanized perforated cable tray easier to install and support, reducing the need for heavy-duty mounting hardware.

2.4 Galvanized perforated cable tray Versatility

  • Galvanized perforated cable trays are compatible with a wide range of cable types and sizes.
  • They can be used for power, data, communication, and other types of cabling applications.

2.5 Cable Organization

  • The galvanized perforated cable tray design helps keep cables organized and routed in a neat, structured manner.
  • This can improve the overall appearance of the cable management system and make it easier to maintain and service the cables.

2.6 Galvanized perforated cable tray Safety

  • The perforations provide visibility of the cables within galvanized perforated cable tray, which can aid in identifying and addressing any issues.
  • The galvanized finish also helps prevent sharp edges that could potentially damage the cables.

2. How Does galvanized perforated cable tray Work ?

3.1 Cable Routing

  • Galvanized perforated cable tray provides a defined pathway to route and support cables, wires, and other types of electrical/data cabling.
  • Cables are laid into the tray and can be secured in place using cable ties or other fasteners.

3.2 Galvanized Construction

  • The steel used to make the tray is coated with a layer of zinc through a process called galvanization.
  • This galvanized coating protects the underlying steel from corrosion, ensuring the tray has a long service life.

3.3 Perforated Cable Tray Design

  • Galvanized perforated cable tray features a series of holes or perforations along its surface.
  • These perforations serve two main purposes:
  1. Improved Airflow: The openings allow for better air circulation around the cables, helping to dissipate heat buildup.
  2. Reduced Weight: The perforations reduce the overall weight of the tray, making it easier to install and support.

3.4 Cable Management

  • The galvanized perforated cable trayhelps organize and contain the cables, keeping them routed in a neat and orderly manner.
  • This improves the overall appearance of the cable management system and makes it easier to access and maintain the cables.

3.5 Galvanized perforated cable tray Installation

  • Galvanized perforated cable trays are typically suspended from the ceiling or mounted on walls using brackets or other support hardware.
  • The galvanized perforated cable tray can be joined together using splice connectors to create continuous cable pathways.
  • Access points and fittings, such as elbows and tees, can be used to route cables around corners and obstacles.

4. How To Make Custom galvanized perforated cable tray?

4.1 Determine the Specifications

  • Measure galvanized perforated cable trayrequired dimensions, such as length, width, and depth, based on your specific application and space constraints.
  • Decide on the perforation pattern and size that will provide the desired airflow and weight characteristics.
  • Consider any special features or accessories, such as mounting brackets, elbows, or tees, that you may need.

4.2 Select the Material

  • Choose a galvanized steel sheet or coil as the base material for galvanized perforated cable tray.
  • Ensure that the steel thickness and gauge are appropriate for the intended load-bearing capacity and span of the tray.

4.3 Cut the Steel

  • Use a metal cutting tool, such as a chop saw, band saw, or shear, to cut the steel sheet or coil to the desired lengths and widths.
  • Take into account any additional length needed for overlaps or connecting sections.

4.4 Perforate the Steel

  • Drill or punch the required pattern of holes or perforations into the steel sheets.
  • The size, spacing, and distribution of the galvanized perforated cable traywill depend on your design requirements.

4.5 Form the Tray

  • Bend the steel sheets to create the desired tray shape, such as a U-channel or a rectangular tray.
  • Use a sheet metal brake or other bending tools to achieve the necessary folds and angles.

4.6 Attach galvanized perforated cable tray Accessories

  • Weld or rivet any necessary accessories, such as mounting brackets, elbows, or tees, to the tray.
  • Ensure galvanized perforated cable traythat the connections are secure and do not interfere with the cable routing.

4.7 Galvanize the Tray

  • Once the galvanized perforated cable trayis fabricated, send it to a galvanizing facility to apply the protective zinc coating.
  • The galvanization process involves submerging the tray in a molten zinc bath, which creates a durable, corrosion-resistant finish.

4.8 Final Assembly and Testing

  • Assemble the galvanized perforated cable traysections, if necessary, using splice connectors or other joining methods.
  • Test the tray’s load-bearing capacity and overall functionality before installing it.

5. Summary

  • Galvanized perforated cable traydesign, combined with the galvanized steel construction, makes these cable trays a popular choice for applications where corrosion resistance, airflow, and cable management are important considerations.
  • By following these maintenance practices, you can help extend the lifespan of your galvanized perforated cable tray and maintain the integrity of your cable management system.
  • Keep in mind that custom fabrication may require specialized tools, equipment, and expertise. It’s recommended to work with a metal fabrication company or a skilled metalworker who has experience in producing custom cable trays to ensure a high-quality and functional end product.
