Product Overview
The LWLSC1101 Heavy-Duty Ductile Iron Manhole Cover & Frame is engineered to meet strict international standards, manufactured from high-grade ductile cast iron conforming to ISO1083 / JS/500-7. Designed to deliver superior tensile strength, durability, and impact resistance, this cover offers exceptional performance compared to traditional grey cast iron.
Rated at Class C250 (250 kN test load) in accordance with EN 124 standards, it is coated with a premium black bitumen finish for long-lasting corrosion, chemical, and weather resistance. The engineered anti-slip surface pattern ensures optimal traction and safety for vehicular and pedestrian traffic.
Key Features & Benefits
High Load-Bearing Capacity: Tested and certified to Class C250 (capable of supporting loads up to 25 tons / 250 kN), ideal for car parks, kerbside channels, and light-to-medium traffic roadways.
Premium Ductile Iron: Produced using ISO1083 / JS/500-7 ductile iron, providing high strength-to-weight ratio, high yield strength, and excellent elongation to prevent brittle cracking.
Corrosion & Weather Resistant: Treated with heavy-duty black bitumen painting to withstand water, road salt, chemicals, and extreme ambient temperatures.
Anti-Slip Raised Pattern: Features a raised checker/grid pattern on the surface to ensure maximum skid resistance and public safety in wet weather conditions.
Secure Seating & Anti-Rattle: Precision-cast frame and cover design ensures stable seating, minimizing vibration and reducing vehicle traffic noise.
