Deck 500 product details
A purpose-made solid-top plank system
Deck 500 is distinct from moulded grating: it is an interlocking, pultruded GRP plank system with a solid gritted surface for specified access and cover applications.
Technical guidance
Deck 500 load-table guidance
The Deck 500 guide shows uniform and centre-point loading data for clear spans from 750 to 1,750 mm. The existing product guidance states that Deck 500 can span 1.5 m at a design load of 5 kN/m² with a deflection limit of L/200.
Load data is indicative only. Confirm the final span, support arrangement, loading, deflection requirement, edge detail and installation method with Captrad for the individual project.

The Deck 500 system
Solid-top interlocking GRP decking for access, covers and walkways
Deck 500 is a one-piece pultruded GRP profile, 500 mm wide and 40 mm deep, with a tongue-and-groove joint running along each plank. The joint produces a firm, sealable connection between lengths, creating a continuous solid-top surface for project-specific access and cover applications.
The profile has a gritted anti-slip surface and can be considered for mezzanine floors, walkways, pedestrian bridge decks, odour-control covers, cooling-tower covers, water-treatment baffles, stop locks and flood-defence barriers. Final selection should always take account of the span, support arrangement, load, surface finish and site interfaces.
Typical Deck 500 applications
- Walkways, mezzanine floors and pedestrian bridge decks
- Odour-control covers for potable-water and wastewater treatment units
- Cooling-tower covers and water-treatment-tank baffles
- Stop locks, flood-defence barriers and industrial access surfaces
Interlocking plank system
A solid-top GRP deck for access and cover applications
GRP Deck 500 is an interlocking pultruded plank system designed for practical access, cover and decking applications. Its one-piece, solid-top construction can be considered where a durable composite surface is needed across walkways, treatment-site covers, bridge decks and similar project areas.
The finished arrangement depends on the application, span, support layout, required surface finish and installation interfaces. Send plans, dimensions, support information and quantities to Captrad so the team can discuss whether Deck 500 is suitable for your project.
- Interlocking solid-top pultruded GRP planks
- Walkways, bridge decks and maintenance routes

Project questions
GRP Deck 500 FAQs
Answers to the questions our technical sales team is most often asked.
What is GRP Deck 500?
GRP Deck 500 is a one-piece pultruded, solid-top GRP plank system. Each plank is 500 mm wide and 40 mm deep, with a tongue-and-groove joint along its length to form a firm, sealable deck surface.
What is Deck 500 used for?
It can be considered for walkways, mezzanine floors, pedestrian bridge decks, odour-control covers, cooling-tower covers, water-treatment baffles, stop locks and flood-defence barriers, subject to the project design.
How do Deck 500 planks join together?
The pultruded planks use a continuous tongue-and-groove joint. This connects adjacent planks along their length and can provide a firm, sealable joint where the installed detail calls for it.
What span and load can Deck 500 achieve?
The Deck 500 technical guidance includes uniform and centre-point load data at clear spans from 750 to 1,750 mm. The existing product guidance states that the system can span 1.5 m at a design load of 5 kN/m² with a deflection limit of L/200; final support and loading must be checked for the individual project.
Is Deck 500 slip resistant?
Yes. Deck 500 has a gritted anti-slip solid-top surface. Confirm the finished surface requirement and site conditions with Captrad when specifying the system.
Can Deck 500 be used in water and wastewater environments?
Yes. It is commonly considered for odour-control covers, potable-water and wastewater-treatment-unit covers, cooling towers and tank baffles. The final arrangement should be designed around the process area, supports and access needs.
What information is needed for a Deck 500 quotation?
Please provide drawings, deck area, required plank direction, clear spans, support arrangement, intended loading, edge details, quantities, site environment and delivery requirements.
