EN124 D400（500*340mm）High-Density SMC Composite Stormwater Grating Cover

The Heavy Duty SMC Drain Grating Cover is manufactured from high-density SMC composite to deliver superior drainage performance and long-term structural durability. Designed for municipal and industrial drainage systems, it combines lightweight construction with excellent load-bearing capacity.

The optimized drainage slot design ensures efficient surface water collection, while the anti-slip surface enhances safety for both pedestrians and vehicles. Certified to EN124 D400, the grating is engineered for heavy traffic applications including roads, logistics parks, parking areas, and commercial developments.

Its non-metallic construction provides excellent resistance to corrosion, UV exposure, chemicals, de-icing salts, and harsh weather conditions. Compared with traditional cast iron grates, it offers quieter operation, zero scrap value, and reduced maintenance throughout its service life.

Features & Benefits:

Weight Loading: Certified to BS EN 124-5 D400 class, our grating covers are engineered for heavy traffic applications with an excellent load-bearing capacity up to 40 tonnes, making them perfect for urban highways, kerbside gullies, logistics parks, and car parks.

Lightweight: Manufactured from high-density SMC composite, it combines its high strength with a lightweight construction that is much lighter than traditional cast iron grates, allowing for easier handling and significantly lower installation costs.

Superior Durability: Its advanced non-metallic construction provides exceptional resistance to corrosion, UV exposure, chemicals, de-icing salts, and harsh weather conditions, ensuring long-term structural integrity throughout its service life.

Increased Safety: Features a specialized anti-slip thread surface and captive structural safety design to ensure maximum slip resistance and stability for both high-speed vehicles and passing pedestrians.

Anti-Theft & Low Maintenance: The premium composite material offers zero scrap value, completely eliminating the risk of theft. Compared with traditional metal alternatives, it delivers quieter traffic operation and drastically reduced maintenance costs.

COMMON APPLICATIONS FOR SMC

SMC (Sheet Molding Compound) is a high-strength, lightweight composite material that combines fiberglass reinforcement with thermosetting resin. It offers excellent corrosion resistance, outstanding electrical insulation, and superior design flexibility, making it an ideal choice for applications requiring both durability and complex geometries across diverse industries, including:

*Municipal infrastructure

*Electrical and power distribution

*Automotive

*Construction and architecture

*Water and wastewater treatment

*Telecommunications
