High Strength Anti Corrosion Composite Manhole Cover Heavy Duty Round Lid for Industrial Sewage Applications

High Strength Anti Corrosion Composite Manhole Cover CMC-HS600

The High Strength Anti Corrosion Composite Manhole Cover CMC-HS600 is purpose-built for high strength industrial sewage and wastewater environments where anti corrosion performance is paramount. Constructed from fiber-reinforced SMC composite with tensile strength exceeding 60 MPa, this heavy-duty round lid withstands aggressive chemical exposure that destroys conventional metal covers.

Key Features

• High Strength Construction: Fiber-reinforced SMC composite delivers tensile strength ≥60 MPa and flexural strength ≥120 MPa, achieving EN124 Class D400 (40 tons) load rating for heavy traffic zones.
• Anti Corrosion Performance: Fully non-metallic body provides complete resistance to acids, alkalis, hydrogen sulfide, and industrial chemical effluents commonly found in sewage and wastewater treatment plants.
• Heavy Duty Load Bearing: D400 certification enables installation on main carriageways, industrial yards, and high-traffic logistics areas subject to heavy truck loading.
• Bolted Lock Security: Integrated bolted locking mechanism prevents unauthorized access and eliminates cover displacement from traffic suction effects.
• Wide Temperature Tolerance: Maintains structural integrity and dimensional stability from -40°C to 80°C, suitable for extreme climate industrial installations.
