Key Specifications

Key Features & Advantages

• Superior Strength & Toughness: Cast from high-grade ductile iron (ISO1083/JS/500-7)[cite: 1], providing significantly higher tensile strength, elongation, and impact resistance than traditional gray cast iron.

• D400 Heavy-Duty Rating: Designed to withstand test loads up to 400kN, perfectly suited for carriage ways of roads, hard shoulders, and parking areas for all types of road vehicles.

• Anti-Slip Tread Pattern: Features a specialized textured surface pattern on the cover to enhance traction and ensure safety for pedestrians and vehicles, even in wet or rainy conditions.

• Long-Lasting Corrosion Protection: Finished with a durable black bitumen painting[cite: 1] that effectively seals the metal surface against moisture, chemicals, and soil elements, reducing maintenance costs.

• Stable Square Frame Design: The square outer frame ensures secure and seamless installation into concrete pavements, sidewalks, and road edges, preventing shifting under heavy traffic loads.

Applications

The LWSRC2001 ductile iron manhole cover is widely applied across multiple infrastructure sectors, including:

• Municipal roads, highways, and urban streets

• Parking lots, multi-level garages, and logistics yards

• Industrial plants, factory grounds, and commercial parks

• Underground utility access for electrical, telecommunications, water supply, and drainage systems
