A Pultruded GRP Interlocking Deck Panel excellent for walkways to odour control covers, GRP Deck 500 covers everything.
DECK 500 is a one-piece pultruded profile, 500mm over width and 40mm thick, with a tongue and groove joint along the length of the plank that gives a firm, sealable joint between the lengths of the profile.
DECK 500 gives a solid floor with a gritted anti-slip surface. It will span 1.5m at a design load of 5kN/m2 with a deflection limit of L/200 and meets all the requirements of BS 4592-4 Industrial type flooring and stair treads Part 5: Solid plates in metal and glass reinforced plastics (GRP) Specification and BS EN ISO 14122 part 2 – Safety of Machinery Permanent means of access to machinery.
Our GRP Deck 500 Decking system meets all the requirements of EN 13706 Specification of grp profiles Grade E23 and is manufactured under ISO 9000 registered quality control system.
GRP DECK 500 is suitable as a mezzanine floor, for walkways, pedestrian bridge decks and odour control covers or to keep out water penetration in potable and wastewater treatment units.
Fiberglass Decking can be used in a number of other applications where its strength, lightweight and ease of joining provide important benefits. For example:
- Deck 500 can be used as deck covers for cooling towers
- Baffles in water treatment tanks
- Stop locks
- Flood defence barriers are easy to install, no theft value

2. What is GRP Deck 500 used for?
GRP Deck 500 is commonly used for walkways, access platforms, maintenance areas, trackside routes, bridges, and industrial access where strength, safety, and long-term durability are essential.
3. How strong is GRP Deck 500?
GRP Deck 500 is engineered to support heavy pedestrian loads and equipment while remaining lightweight. Its high strength-to-weight ratio makes it suitable for infrastructure and industrial applications where traditional materials may fail.
4. Is GRP Deck 500 suitable for outdoor use?
Yes. GRP Deck 500 is UV-stable, weather resistant, and performs reliably in extreme temperatures, wet conditions, and harsh outdoor environments without degrading.
5. Is GRP Deck 500 slip resistant?
Yes. GRP Deck 500 features an integral anti-slip surface designed to provide excellent traction, even in wet, oily, or contaminated conditions, helping to improve safety and reduce slip risks.
6. Does GRP Deck 500 corrode or rot?
No. Unlike steel or timber, GRP Deck 500 does not rust, rot, or corrode. It is resistant to moisture, chemicals, salts, and biological growth, making it ideal for long-term installations.
7. How long does GRP Deck 500 last?
GRP Deck 500 has an expected service life of 25–30+ years with minimal maintenance, even in aggressive industrial or coastal environments.
8. Is GRP Deck 500 easy to install?
Yes. GRP Deck 500 is significantly lighter than steel or concrete alternatives, allowing for faster installation, reduced manual handling risks, and lower installation costs.
9. Is GRP Deck 500 fire resistant?
GRP Deck 500 can be manufactured using fire-retardant resin systems to meet relevant fire performance requirements for infrastructure and industrial projects.
10. Why choose GRP Deck 500 over steel or concrete decking?
GRP Deck 500 offers superior corrosion resistance, lighter weight, improved safety, lower maintenance, and a longer lifecycle cost advantage compared to steel or concrete decking systems.
