Product Overview
The LWLSC6001 Ductile Iron Manhole Cover and Frame is engineered for high-performance municipal, roadway, and utility infrastructure applications. Manufactured from premium ductile iron conforming to ISO 1083 / JS 500-7 (EN-GJS-500-7), this heavy-duty manhole cover delivers outstanding tensile strength, impact resistance, and durability under heavy vehicular traffic.
Certified to meet EN 124 Class D400 standards with a test load capacity of 400 kN (40 Tons), the LWLSC6001 is ideally suited for main roads, highways, distribution centers, and industrial access routes where maximum stability, noise reduction, and public safety are paramount.
Key Features & Advantages
High Load-Bearing Capacity (D400): Engineered and tested to support loads up to 400 kN, fully compliant with international highway and municipal road standards.
Superior Ductile Iron Construction: Cast from high-grade ISO 1083 / 500-7 ductile iron, providing higher elongation and fracture resistance than traditional gray cast iron.
Anti-Corrosive Surface Protection: Coated with high-grade black bitumen painting (or optional epoxy coating) for exceptional resistance to road salt, moisture, and chemical corrosion.
Anti-Slip & Silent Seating: Features an engineered textured surface for superior skid resistance and an optional rubber/EPDM gasket to eliminate traffic noise and rattling.
Security & Anti-Theft: Equipped with secure locking provisions and precision-machined frame seating to deter unauthorized entry and vandalism.
