GRP and FRP are both composite materials that are made up of a matrix and a reinforcement. The matrix is a polymer that holds the reinforcement together,and the reinforcement provides strength and stiffness.

What is GRP?

GRP (Glass-Reinforced Plastic): This term specifically refers to FRP where the reinforcing fibers are made of glass. GRP is more widely used in Europe and Asia.

What is FRP?
 

FRP (Fiber-Reinforced Plastic): This is the broader term, encompassing any composite material where plastic is strengthened with fibers. These fibers can be made of glass, carbon, aramid (like Kevlar), basalt, or other materials. FRP is more commonly used in North America.

What are the similarities between GRP and FRP?

GRP and FRP are both composite materials that are made up of a matrix and a reinforcement. They are both strong, lightweight, and corrosion-resistant.

What are the differences between GRP and FRP?
 

In essence, GRP is a type of FRP, but not all FRP is GRP. When choosing between them, it depends on the specific properties you need. Here are some generalities:

Strength and Elasticity: FRP using fibers like carbon can be stronger and stiffer than GRP.

Heat Resistance: Some FRP types can have better heat resistance than GRP.

Applications: FRP is used in a wider range of industries like automotive, aerospace, and construction. GRP is more common in the power industry.

Which material is right for you?
 

If you're unsure which term to use, FRP is generally a safe bet as it's the broader term. But if you know for sure the reinforcement is fiberglass, then GRP is the more specific term.

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.
