MR690-D
Elite
This flame-retardant SMC manhole cover is engineered for pedestrian zones and light-traffic areas, serving as a durable access solution for sewerage, telecommunication, and underground electrical networks. Made from sheet molding compound — a glass fiber-reinforced thermosetting resin composite — the cover delivers consistent mechanical strength and long-term stability under rated operating conditions. It provides a functional alternative to cast iron and concrete access covers, addressing common industry pain points such as corrosion, metal theft, and excessive unit weight.
Certified to EN124 standards, the product is available in multiple load ratings to match distinct application scenarios. Its built-in flame-retardant property supports fire safety requirements for public pedestrian infrastructure, adding risk mitigation value for municipal and commercial facility projects.
SMC composite material resists rust, corrosion, and exposure to common industrial and environmental chemicals. Unlike metal access covers that degrade over time in humid or saline environments, this SMC manhole cover retains structural integrity with regular contact with water, road salts, oils, and mild chemical agents. This makes it suitable for installation in coastal zones, industrial parks, sewer systems, and urban areas with variable environmental conditions.
The SMC formulation incorporates flame-retardant additives, which support fire safety performance in public pedestrian areas. This property limits flame spread in the event of nearby fire incidents, aligning with standard safety specifications for public utility access points.

Each load class corresponds to defined use cases: A15 for exclusive pedestrian zones, B125 for pedestrian areas with occasional light vehicle access, C250 for commercial parking zones, and D400 for main roadways with heavy truck traffic. Buyers may select the appropriate class based on on-site traffic conditions.
The cover’s top surface is manufactured with a precision anti-slip texture, which reduces slip and fall risks for pedestrians during wet or icy weather. Additionally, the non-conductive SMC material eliminates electrical conduction risks for sites with underground power or telecommunication cables, lowering safety hazards for maintenance staff and passing pedestrians.
This SMC manhole cover has a reduced unit weight compared to equivalent cast iron products. The lower weight reduces per-unit transportation costs and allows on-site installation without heavy lifting equipment. Workers can position and adjust the cover manually under proper safety protocols, improving installation efficiency and reducing labor input for commercial procurement projects.
The cover contains no recyclable metal components, eliminating the scrap theft risk associated with traditional cast iron access covers. This reduces replacement costs and maintenance frequency for municipalities and facility management teams, supporting consistent long-term operation of underground utility networks.
A range of customization options are available to align with specific project requirements, including adjustments to shape, dimensions, load rating, and surface color. Buyers may also request custom surface markings such as utility identification codes, company logos, or unique texture patterns to meet regulatory or branding needs. Functional add-ons such as watertight seals, hinge systems, and locking devices are also available for sensitive utility networks or restricted-access sites.
For exclusive pedestrian zones including sidewalks, park paths, and public plazas, the A15 load rating class meets EN124 requirements. For areas with occasional light vehicle access, the B125 class is a compatible option.
Yes. The SMC composite material resists corrosion from salt moisture and saline air, allowing stable performance in coastal regions without rust formation over long-term use.
Custom surface markings and functional add-ons are available for bulk project orders. Buyers may contact the sales team with specific project parameters to receive detailed ordering and lead time information.
