Ductile iron manhole cover D400 Openong550

The product details of a Ductile iron manhole cover with an opening size of 550mm (D400) are as follows:

1. Material: The manhole cover is made of ductile iron, which is a type of cast iron known for its high strength, durability, and impact resistance.

2. Load Rating: The D400 load rating indicates that the manhole cover is designed to withstand a maximum load of 40 tonnes. This makes it suitable for heavy-duty applications such as highways, airports, and industrial areas.

3. Design: The manhole cover is designed with an opening size of 550mm, which refers to the diameter of the circular opening through which access to the underground utility or infrastructure is provided.

4. Surface Treatment: The manhole cover is typically coated with a protective finish, such as bitumen or epoxy, to enhance its resistance to corrosion, weathering, and wear.

5. Locking Mechanism: To secure the manhole cover in place and prevent unauthorized access, it may feature a locking mechanism, such as a bolt or latch system.

6. Safety Features: The manhole cover may include safety features like anti-slip patterns or raised edges to enhance traction and prevent accidents caused by slips or trips.

7. Standards Compliance: The D400 manhole cover is manufactured in compliance with relevant industry standards and specifications, such as EN 124 or AASHTO M306, to ensure its quality, performance, and compatibility with existing infrastructure.

8. Weight: The weight of the manhole cover can vary depending on its size and design, but it is typically heavier than lower load-rated covers to withstand heavy traffic loads.

9. Installation: The manhole cover is designed to be installed flush with the surrounding surface, providing a smooth and level finish that minimizes the risk of tripping hazards or damage to vehicles.

10. Application: The D400 manhole cover is commonly used in areas with heavy traffic, such as roads, highways, airports, ports, and industrial sites, where it provides access to underground utilities like sewer lines, water mains, or telecommunications infrastructure.
