MR690-D
Elite
Model MR690-D anti-slip composite manhole cover is engineered for urban infrastructure and utility access applications. It provides secure access to underground sewer systems, drainage networks, and telecommunications lines, with specifications aligned to the needs of city engineering departments and infrastructure contractors. Built with SMC composite material, this product supports installation across public works and commercial utility projects.
This manhole cover is manufactured from Sheet Molding Compound (SMC), a non-metallic composite material. Compared to traditional cast iron covers, the SMC structure delivers required load-bearing capacity with a lower overall unit weight. The non-metallic composition eliminates scrap metal value, which reduces theft risk in both urban and remote utility locations.
The cover top features a molded textured pattern designed to increase surface friction. Formed during the primary molding process, the texture remains consistent across the entire cover surface. This anti-slip design supports pedestrian and vehicular traction in wet, icy, or damp outdoor conditions.

All units undergo testing for load-bearing capacity, material tensile strength, and UV resistance during production. ISO and SGS certification documentation is available upon request for commercial procurement compliance verification.
The SMC composite material does not rust or corrode when exposed to soil, moisture, and urban environmental conditions. This material characteristic reduces replacement needs caused by corrosion damage compared to metal manhole covers, supporting extended service life in outdoor installations.
As a non-conductive material, SMC composite provides electrical insulation for underground utility access points. This property makes the covers suitable for installation over power distribution and telecommunications networks, reducing conduction risk during maintenance operations.
Watertight and airtight frame designs are available for projects requiring odor containment and groundwater infiltration prevention. Each cover is precision-molded to match its corresponding frame dimensions, creating a consistent, secure fit after installation.
Standard product lines cover load classes for light pedestrian zones up to heavy-duty roadway applications. For project-specific requirements, custom dimensions, surface colors, and municipal or brand logos can be integrated into the molding process. All custom requests are evaluated based on project scale and technical feasibility.
Production follows standardized quality control protocols, with inspection checkpoints covering material formulation, molding accuracy, and performance testing. The manufacturing process draws on 20+ years of composite material production experience. Pre-shipment inspections verify dimensional accuracy and surface integrity for every batch.
The EN124 D400 load class is specified for urban roadways, public parking areas, and access lanes with regular passenger and light commercial vehicle traffic. It also applies to utility access points in municipal infrastructure, airport zones, and port facilities.
Custom text and logos can be molded into the cover surface to support municipal branding or project identification requirements. Custom color options are also available to align with site design specifications.
Composite manhole covers require minimal routine maintenance. The non-corrosive material does not need rust treatment or repainting over its service life. Regular visual inspections to confirm proper seating and surface condition are sufficient for most installation sites.
These composite manhole covers are specified for durable, low-maintenance urban access solutions. For project-specific quotes and technical consultation, submit your project dimensions and requirement details.
