Captrad’s GRP Cable Troughs are produced bespoke to customer specification. The GRP Moulded Trough is reinforced with additional structural profiles, this design and weight savings offer massive advantages over traditional concrete troughs.
GRP Troughs can offer in the region of 80-90% in weight-saving, thus in return, this allows more troughs to be transported and allows a quicker installation making the overall cost of the product far more beneficial. These traits of GRP troughs also have less of an impact on the environment in relation to transportation and personnel.
GRP is a durable and lightweight material that offers excellent resistance to corrosion and environmental factors, making it an ideal choice for cable management systems. Our GRP cable troughs are designed to provide a secure and organized solution for the installation and support of cables across various environments, including industrial, commercial, and even harsh outdoor conditions.
Here are some key features and benefits of our GRP cable trough:
1. Material strength and longevity: GRP is known for its exceptional strength-to-weight ratio, ensuring that our cable troughs can withstand heavy loads while maintaining structural integrity. This inherent strength also contributes to their longevity, making them a cost-effective investment.
2. Corrosion resistance: Unlike traditional metal cable troughs, our GRP solution is inherently resistant to corrosion caused by moisture, chemicals, and extreme temperatures. This characteristic ensures a prolonged service life and minimizes maintenance requirements.
3. UV resistance: Our GRP cable troughs are formulated with UV inhibitors, providing excellent resistance against harmful ultraviolet rays. This feature allows our cable troughs to maintain their physical properties and colour stability over extended periods, even when exposed to intense sunlight.
4. Fire resistance: Safety is of utmost importance when it comes to cable management. Our GRP cable troughs meet the required fire performance standards, offering enhanced fire resistance compared to other materials. This specification ensures the protection of cables and reduces the risk of fire propagation in critical environments.
5. Easy installation and adaptability: Our GRP cable troughs are designed for ease of installation, with flexible configurations to accommodate various cable sizes and layouts. The lightweight nature of the material simplifies handling, reducing installation time and costs.
6. Low maintenance: GRP cable troughs require minimal maintenance due to their resistance to corrosion. Regular inspections and routine cleaning are typically sufficient to ensure optimal performance.
We understand that each project has unique requirements, and our team of experienced professionals is available to provide technical support and guidance to ensure the success of your cable management system. We pride ourselves in delivering high-quality products that meet industry standards while addressing customer needs.
Captrad are able to produce a range of Moulded GRP troughs in various sizes to cater for any project. We also offer Bends, Risers and T Junctions to aid with the schematics of the cables, as we can mould bespoke solutions we can virtually cater for any project.
With the use of GRP Structural shapes, we can divide the troughs if necessary to create compartments for various uses.

Frequently Asked Questions About GRP Grating
1. What are GRP cable troughs?
GRP cable troughs are cable management systems manufactured from Glass Reinforced Plastic. They are used to protect and route electrical and data cables in rail, infrastructure, utilities, and industrial environments.
2. What are GRP cable troughs used for?
GRP cable troughs are commonly used for railways, highways, substations, renewable energy projects, utilities, and industrial sites to safely house power, signalling, and communication cables.
3. Are GRP cable troughs better than concrete cable troughs?
Yes. GRP cable troughs are lighter, non-corrosive, easier to install, and require significantly less maintenance than concrete cable troughs, making them a more cost-effective long-term solution.
4. How long do GRP cable troughs last?
GRP cable troughs typically have a service life of 30+ years. They do not rot, rust, crack, or degrade in harsh weather or chemical environments.
5. Are GRP cable troughs suitable for outdoor use?
Yes. GRP cable troughs are UV-stable, weather resistant, and perform well in extreme temperatures, making them ideal for permanent outdoor installations.
6. Do GRP cable troughs meet railway and infrastructure standards?
High-quality GRP cable troughs are manufactured to meet relevant rail, infrastructure, and utility specifications, including fire performance, load bearing, and durability requirements.
7. Are GRP cable troughs fire resistant?
GRP cable troughs can be manufactured using fire-retardant resin systems to meet specific fire performance standards required for rail and infrastructure projects.
8. Are GRP cable troughs easy to install?
Yes. GRP cable troughs are significantly lighter than concrete, allowing for faster installation, reduced manual handling risks, and lower installation costs without heavy lifting equipment.
9. Do GRP cable troughs corrode or degrade over time?
No. GRP cable troughs are resistant to corrosion, moisture, chemicals, salts, and biological growth, making them ideal for aggressive or damp environments.
10. Are GRP cable troughs environmentally friendly?
GRP cable troughs have a long lifespan, require minimal maintenance, and reduce replacement frequency, which lowers overall environmental impact compared to concrete alternatives.
