GRP / Fibreglass Panel Signs- Durable, Lightweight & Built to Last
At Complete Signs, we design, manufacture and install GRP (Glass Reinforced Plastic) signs, also known as fibreglass panel signs, that combine strength, versatility, and bold visual appeal. These signs are ideal for businesses, schools, local authorities and community spaces looking for a cost-effective yet durable signage solution.
Whether you need custom-shaped panels for your school entrance, post-mounted location signs, or wall-mounted external signage, our GRP signs are built to withstand both the weather and wear.
Why Choose GRP Panel Signs?
GRP signs offer an exceptional balance of strength, weight and visual clarity. They’re highly adaptable and can be manufactured to your exact specifications, including:
- Custom shapes with clean, moulded edges
- Digitally printed designs with bold, long-lasting colour
- UV-resistant surfaces that won’t fade in sunlight
- Vandal-resistant and weatherproof construction
- Lightweight but extremely strong, making them ideal for railings, walls, posts or freestanding structures
GRP panel signs are especially popular in educational environments, leisure facilities, housing developments, and public sector locations due to their combination of durability and design flexibility.
Fully Customised, Professionally Installed
We offer a wide range of finishes, sizes and mounting options to ensure your GRP signage suits its intended space—indoors or outdoors. These signs can be flat-panelled or domed, single or double-sided, and installed on walls, posts or railings with high-grade fixings to guarantee stability.
Every sign is manufactured in-house and tailored to your specific needs—whether that’s a school welcome sign, a neighbourhood notice board, or a wayfinding panel for a public park.
