Square & Rectangular Manhole Cover

Product Description

High-Strength Square & Rectangular Ductile Iron Manhole Covers

As an experienced municipal casting manufacturer, we provide premium Square & Rectangular Ductile Iron Manhole Covers designed for superior stability and seamless pavement integration. Unlike round covers, our square and rectangular profiles are perfectly tailored for pedestrian plazas, walkways, parking lots, and urban kerbsides, allowing for clean, efficient alignment with modular paving blocks and tiles.

Manufactured from high-grade Ductile Iron (GGG50) in strict accordance with the EN 124 standard, these covers are built to deliver exceptional load-bearing performance, ranging from B125, C250 to D400 classes. The precise engineering ensures an exact fit between the cover and the frame, minimizing movement and eliminating noise under vehicular traffic.

Key Features:

• Optimal Pavement Alignment: The straight-edge square/rectangular design integrates cleanly into stone or brick paved areas, maintaining aesthetic harmony.

• Excellent Load Capacity: Crafted from heavy-duty ductile iron, ensuring high tensile strength and impact resistance without cracking under pressure.

• Anti-Slip & Safe Surface: Features raised, scientifically designed anti-skid surface patterns to ensure maximum safety for both vehicles and pedestrians.
