Fiber reinforced polymer (FRP) cable trays are a type of cable management system that is becoming increasingly popular. They offer a number of advantages over traditional steel cable trays, including corrosion resistance, lightweight construction, and fire resistance.

 

Advantages of FRP Cable Trays

Corrosion resistance: FRP cable trays are made of a composite material that is resistant to corrosion from a variety of chemicals and environmental factors. This makes them ideal for applications in harsh environments, such as marine and industrial settings.

Lightweight construction: FRP cable trays are significantly lighter than steel cable trays. This makes them easier to install and move, and it can also save money on shipping costs.

Fire resistance: FRP cable trays are fire resistant and can help to protect cables from fire damage. This is an important consideration for applications in public buildings and other areas where fire safety is a concern.

 

Disadvantages of FRP Cable Trays

Cost: FRP cable trays are generally more expensive than steel cable trays. However, the cost savings associated with installation and maintenance can offset the initial investment.

Strength: FRP cable trays are not as strong as steel cable trays. This means that they may not be suitable for applications where high loads are expected.

Conclusion
 

FRP cable trays offer a number of advantages over traditional steel cable trays. They are corrosion resistant, lightweight, and fire resistant. However, they are also more expensive and not as strong as steel cable trays. The best type of cable tray for a particular application will depend on the specific requirements of that application.

Additional Considerations

In addition to the factors discussed above, there are a few other considerations that should be taken into account when choosing between FRP and steel cable trays. These include:

Application: FRP cable trays are typically used in applications where corrosion resistance, lightweight construction, or fire resistance are important considerations. Steel cable trays are typically used in applications where strength or cost are important considerations.

Environment: FRP cable trays are more resistant to harsh environments than steel cable trays.

Maintenance: FRP cable trays require less maintenance than steel cable trays.

By carefully considering the factors that are important for a particular application, engineers can select the best type of cable tray for the job.

FRP Cable Tray - Channel, Perforated, Ladder Style

FRP cable tray is a shortened form of fiberglass reinforced plastic cable tray. It is also called GRP cable tray (glass reinforced plastic cable tray). FRP cable tray is formed through fiberglass pultrusion and continuous mechanized production process. According to the shape, FRP cable trays can be sorted into ladder type cable trays, channel type cable trays, perforated cable trays and large span cable trays. FRP cable trays are lighter than common steel cable trays. They have good corrosion-resistant and fire retardant properties so that they are mainly used to support insulated electric cables for power distribution in chemical industries, communications industries, oil and gas industries, metallurgy industries, etc.

FRP channel type cable tray has I-beam rails and the cover is used to protect cable from falling objects, dust and water

The corrosion-resistant FRP cable tray is suitable for supporting cables in harsh outer environment

Features:

• Corrosion resistant. FRP material has good corrosion resistant property and makes it desirable for severely corrosive environment.
• Resistant to UV, electricity, salt water and chemicals.
• Endure high temperature and fast disperse heat.
• High strength and rigidity. FRP cable trays are strong enough to withstand high load bearing capacity of cables.
• FRP cable trays with covers protect cables from falling objects, dust and water.
• Dimensional stability without shrinking and swelling.
• Lighter and easier to work. FRP cable trays are 40% lighter than stainless steel cable trays. They are easily cut and installed with fasteners.
• Versatile structure. FRP cable trays have versatile structures such as ladder type cable trays, channel cable trays, perforated cable trays, large span cable trays.
• Available in many colors such as green, red, gray, etc.
• Long service life than traditional building materials.
• Low maintenance.

The GRP cable trays are corrosion-resistant and strong enough to support cables in outer offshore platform

Pultrusion process
During the pultrusion process, the raw materials are pulled through a heated steel forming die using a continuous pulling device by pultrusion technology.

Structure
A complete FRP cable tray is composed of straight run, horizontal bend, horizontal tee, horizontal cross, straight reducer, left reducer, right reducer, vertical outside bend, vertical inside bend connected with splice plates, clamps, brackets, etc.

Applications
FRP cable trays are usually installed on the inside or outside wall of computer server room, chemical and purification plants, oil and gas industries, communication company to support computer cables, controlling cables.
