Frequently Asked Questions
GRP stands for Glass Reinforced Plastic, also known as fibreglass. It’s a composite material made from glass fibres and thermosetting resin, offering exceptional strength, corrosion resistance, and low weight.
GRP products are lightweight, strong, corrosion-resistant, and non-conductive, making them ideal for harsh or hazardous environments. They also require very little maintenance and can deliver a long service life even in aggressive or corrosive environments.
Yes — GRP performs exceptionally well outdoors. It is UV-stable, weatherproof, and corrosion-resistant, making it perfect for coastal, marine, and exposed sites where metal would quickly degrade.
Absolutely. PJNC provides fully bespoke GRP design, manufacture and installation services. Our in-house team can create GRP systems tailored to your site dimensions, load requirements and compliance standards.
With proper design and installation, GRP products can achieve service lives in excess of 50 years. Their inherent corrosion resistance allows them to retain structural integrity far longer than steel or aluminium in aggressive environments.
Yes. PJNC Ltd operates throughout the UK and Ireland, with projects also completed in Europe and the Middle East. We handle everything from small one-day installs to large-scale industrial builds.
Yes. All PJNC GRP systems are manufactured and installed in line with relevant UK and international standards, including BS EN ISO requirements for structural performance and safety.
Lead times vary depending on design complexity and project scope, but many GRP systems can be designed, fabricated, and installed within 2–6 weeks.
Yes. GRP products can be manufactured with fire-retardant resins to meet specific fire performance requirements, including flame spread and smoke generation classifications, depending on the application.
In many applications, yes. GRP offers a lightweight, corrosion-resistant alternative to steel, particularly in environments where corrosion, conductivity, or maintenance are concerns. Load requirements and design criteria are assessed on a project-by-project basis.
GRP systems require minimal maintenance compared to traditional materials. They do not rust, rot, or require protective coatings, making them ideal for long-term installations in harsh environments.
Yes. PJNC provides site surveys, technical assessments, load calculations, and detailed drawings to ensure GRP systems are correctly specified and compliant with project requirements.
