MR690-D
Elite
Designed for municipal and roadway infrastructure environments, the MR690-D SMC composite manhole cover is built for long-term use under daily traffic and varied outdoor conditions. Made from Sheet Molding Compound (SMC) and compliant with EN124 standards, it is available in multiple load classes to match different project requirements. It serves as an alternative to traditional metal manhole covers for infrastructure contractors, facility operators and commercial procurement teams, addressing common pain points such as corrosion management and on-site installation efficiency.
The MR690-D is manufactured from Sheet Molding Compound, a fiber-reinforced composite formed through high-temperature, high-pressure molding. This process creates a dense, dimensionally stable structure that maintains consistent performance under repeated loads and environmental exposure. The composite balances structural strength with moderate flexibility, absorbing regular impact loads without cracking. The material contains no metallic components, so it carries no scrap metal recycling value.
This manhole cover line meets EN124 European standard requirements for vehicular and pedestrian area gully tops and manhole tops. It is available in six load classes: A15, B125, C250, D400, E600 and F900, covering scenarios from light pedestrian zones to heavy industrial and airport traffic. Buyers can select the appropriate class based on their project’s actual traffic load.
SMC composite material does not rust, and resists damage from common chemicals and salt spray. This makes the product suitable for coastal cities, industrial zones and chemical plant sites where metal covers require regular anti-corrosion treatment. The material retains its structural condition and surface appearance over long-term use without protective painting or routine anti-rust maintenance.
The SMC material is non-conductive and spark-free on impact, reducing electrical hazard risks for power, telecommunication and gas pipeline installations. Its molded anti-slip surface pattern increases friction under wet or frosty conditions to reduce pedestrian slip risks and maintain vehicle traction. A locking system is available as an optional feature to restrict unauthorized access.
At equivalent load ratings, the MR690-D weighs approximately one-third of a comparable cast iron manhole cover. Reduced weight lowers transportation costs and allows manual installation without heavy lifting equipment, improving on-site work efficiency and reducing physical strain on installation crews. The lightweight design also simplifies access during routine pipeline inspection and maintenance.

This SMC manhole cover is used across a wide range of infrastructure and industrial applications, including road and highway construction, sidewalks and pedestrian zones, telecommunication networks, water supply and drainage systems, power distribution facilities, residential and commercial developments, airport transportation hubs, industrial zones and chemical plants.
This SMC composite manhole cover complies with EN124 standards, with load classes from A15 (light pedestrian traffic) to F900 (heavy industrial and airport traffic). The range covers use cases from residential sidewalks to major highways and heavy industrial facilities.
SMC composite covers weigh less than cast iron covers of the same load class, and resist rust and chemical corrosion. They are non-conductive and have no scrap metal value, and require less routine anti-corrosion maintenance. Cast iron covers have a longer application history in infrastructure, and may be specified for projects with explicit material requirements.
Customization options include adjusted shapes, custom colors and embossed logos. These modifications are integrated into the molding production process, and the design team works with clients to align the final product with specific project and branding requirements.
Under proper installation and routine maintenance, SMC composite manhole covers can have a service life of 30 years or more in most common environmental conditions. Actual service life varies based on traffic load frequency, environmental exposure and maintenance practices.
SMC material resists salt erosion, making these covers applicable for coastal urban and infrastructure projects. Unlike cast iron, which requires regular anti-corrosion treatment in salt-air environments, SMC covers maintain structural performance without additional anti-rust upkeep.
