Product Description

Heavy-Duty Round Ductile Iron Manhole Covers

As a leading manufacturer of municipal castings, we specialize in producing high-grade Round Ductile Iron Manhole Covers designed to withstand the toughest traffic conditions. Known for its superior tensile strength and impact resistance, our ductile iron (GGG50) covers offer a lighter yet significantly stronger alternative to traditional grey iron castings.

Manufactured in strict compliance with the EN 124-2 standard, our round manhole covers are available in various load-bearing classes from B125, C250 to D400 and E600, making them ideal for urban highways, pedestrian zones, residential areas, and commercial docks. The classic round design prevents the cover from accidentally falling into the frame, ensuring maximum safety during installation and maintenance.

Key Features:

• Anti-Theft & Hinge System: Equipped with strong captive hinges and advanced locking mechanisms to prevent vandalism and unauthorized access.
