Ductile Iron Manhole Cover LWGT1001

Product Overview

The LWGT1001 Ductile Iron Gully Grating / Manhole Cover is engineered for heavy-duty surface drainage and municipal water management. Manufactured from high-grade ductile iron conforming to ISO 1083 / JS 500-7, it offers exceptional tensile strength, impact resistance, and durability under demanding traffic loads.

Rated for EN124 Class D400 loading (up to 400 kN / 40 tonnes), this grate is designed for main roads, highways, parking areas, and heavy industrial facilities. The sloped, high-inflow bar spacing ensures rapid stormwater evacuation while effectively preventing road ponding and hydroplaning.

Key Features

• D400 Heavy-Duty Load Capacity: Certified to withstand high wheel loads up to 40 tonnes, making it safe for arterial carriageways and commercial vehicle transit.

• Superior Material Performance: Made of ductile iron (ISO 1083 / JS 500-7) with high elongation and shock-absorbing properties, preventing brittle fractures common in traditional grey iron.

• Efficient Drainage Flow: Precision-cast parallel bar slots maximize hydraulic water intake capacity while catching large debris.

• Corrosion & Weather Resistant: Coated with high-performance black bitumen painting to resist moisture, road salts, chemicals, and oxidation.

• Anti-Theft & Stability: Heavy cast construction (approx. 65 kg) provides substantial seated stability under dynamic traffic, reducing displacement and noise.
