Complete D400 composite cover range engineered specifically for petroleum retail environments. Non-conductive, watertight, and theft-proof — meeting the exact requirements of modern fuel station design.
All four models are D400-rated and designed for direct installation in petroleum retail forecourt environments. Select a model to view details.
Large-diameter round composite cover for fuel station forecourt utility access and tanker delivery areas. D400-rated for all heavy vehicle traffic. Standard watertight frame seal.
Specialist cover with two independent inspection ports, allowing simultaneous or sequential access to two separate systems within a single sump — without removing the main cover.
The industry-standard access cover for fuel containment sumps. Watertight IP68 seal prevents surface water and fuel ingress. Available with or without inspection hole and locking mechanism.
Small-diameter D400 composite cover for individual sensor access, vent points, and small utility connections within the fuel station forecourt. Full D400 load rating despite compact size.
Extra-large diameter round composite cover for wide-bore fuel station sumps, large underground tank access, and multi-pipe utility chambers. C250-rated for light to medium vehicle traffic areas.

Each position in a fuel station forecourt has specific load and access requirements. Our five-model range covers every zone.
High-load zone where fuel tankers approach and connect to underground storage. Requires D400 rating for repeated 40-tonne axle loads.
900×900 D400 900mm D400Primary access to fuel containment sumps housing submersible pumps, vapour recovery systems, and leak detection equipment.
900×900 D400 900 DIP D400Small access points for interstitial leak detection sensors, STP vent connections, and electronic monitoring systems embedded in the forecourt slab.
350mm D400In fuel station environments, material choice is a safety and operational decision — not just a procurement one.
Metal covers can generate sparks if struck by tools or vehicle components in fuel vapour atmospheres. SMC composite is electrically non-conductive by material — this risk is eliminated by design, not by procedure or warning signage.
Fuel containment regulations require sumps to remain sealed against surface water ingress. Our EPDM gasket system maintains IP68 integrity throughout the cover's service life — unlike metal covers whose sealing surfaces degrade from corrosion.
Petrol, diesel, and forecourt cleaning chemicals accelerate corrosion in ferrous metal covers, eventually compromising both seal and structural integrity. SMC composite is chemically inert to all standard petroleum products.
We produce our own SMC compound in-house. This means we control the formula — fibre content, resin chemistry, and filler — optimised specifically for fuel station load and chemical conditions. No third-party material variability.
The right model depends on your sump type and access requirements:
All D400 covers are suitable for heavy vehicle traffic areas in petrol stations. If you have project drawings, send them to us and we'll advise the right model for each position.
On the 900 DIP D400 model, DIP stands for Double Inspection Port. It means the cover is fitted with a small, dedicated inspection hatch in the centre, used for:
…without removing the whole heavy cover. This design is widely used for fuel station sumps and underground tanks where frequent access is required.
Yes. We are an approved supplier to both PetroChina and Sinopec station construction and refurbishment programmes. We can provide verification documentation on request. We also supply OEM-branded covers with operator logos moulded into the surface for branded station builds. Contact us with your project details and we will provide the relevant qualification documents.
Yes. Logos and text can be moulded directly into the anti-slip surface pattern. We supply branded covers for major oil company programmes. Minimum quantities apply for custom tooling. Provide your artwork and programme volume when requesting a quote and we will advise on feasibility and pricing.
Lead times depend on order volume, specification, and whether custom OEM marking is required. Standard covers for small and medium projects are typically available faster than custom tooling orders. Contact us with your project timeline and required quantities and we will provide a specific lead time with your quotation.
