Ductile Iron Manhole Cover: A Reliable Solution for Road Construction

Ductile iron manhole covers, also known as grey iron manhole covers, are widely used in road construction due to their high strength and cost-effectiveness. Made from a type of iron that is similar to carbon steel but more affordable, ductile iron manhole covers offer exceptional corrosion resistance, super toughness, and strength, ensuring they remain undamaged and functional for over 30 years.

These versatile manhole covers can be designed in various shapes, including round, square, rectangular, and double-triangular, to suit different requirements. They are classified into 6 different loading classes based on the European standard EN124: A15, B125, C250, D400, E600, and F900. Each class is designed to handle specific load levels to meet the demands of different applications.

Loading Classes:

• F900 (Heavy Duty) - Loading ability 900KN, 90T. Suitable for docks, airports, and areas with large transport vehicles like trucks and transport aircraft.
• E600 (Heavy Duty) - Loading ability 600KN, 60T. Ideal for main roads, highways, and industrial estates with large transport trucks.
• D400 (Medium Duty) - Loading ability 400KN, 40T. Recommended for main roads, commercial parks, industrial parking areas, and ordinary trucks, pickups, and buses.
• C250 (Medium Duty) - Loading ability 250KN, 25T. Suitable for pavements, gardens, and small car parking areas, generally accommodating ordinary household small vehicles.
• B125 (Light Duty) - Loading ability 125KN, 12.5T. Designed for pedestrian areas, typically allowing pedestrians, bicycles, and similar light vehicles.
• A15 (Light Duty) - Loading ability 15KN, 1.5T. Intended for pedestrian areas, providing passage for pedestrians, bicycles, and similar light vehicles.

For sidewalks, the manhole covers can be designed to be thinner and lighter, meeting load requirements while reducing costs. On the other hand, for high-traffic areas such as airports, docks, and main roads, the manhole covers are thickened and strengthened to ensure they can withstand heavy weights.

Typically, these manhole covers are coated with black bitumen or epoxy, with a thickness of at least 250 microns, to enhance their durability and longevity.

設置、メンテナンス、交換:

Ductile iron manhole covers are relatively easy to install and maintain. They can be securely fixed on the designated openings using appropriate fasteners, ensuring a tight and stable fit.

Regular maintenance involves inspecting the covers for any signs of damage, corrosion, or wear. Cleaning the covers and surrounding areas is also recommended to prevent debris buildup. In the event of damage or wear, the covers can be replaced with new ones, ensuring the continued safety and functionality of the manhole.
