Ductile iron manhole cover D400 Openong600

Product details of a ductile iron manhole cover with a D400 load rating and an opening size of 600mm:

- Material: Ductile iron, also known as nodular cast iron or spheroidal graphite iron.
- Load Rating: D400, which means it can withstand a maximum load of 40 tons (400 kN) according to the EN 124 standard.
- Opening Size: 600mm, referring to the diameter or width of the manhole cover's opening.
- Design: The Manhole cover is designed to be round with a 600mm diameter opening. It may have a solid or slotted top surface, depending on the specific design and purpose.
- Features: Ductile Iron Manhole Covers are known for their high strength, durability, and resistance to cracking or breaking. They are also resistant to corrosion, making them suitable for various environments, including roads, sidewalks, and industrial areas.
- Coating: The Manhole Cover may have a protective coating, such as bitumen or epoxy, to enhance its resistance to corrosion and improve visibility (e.g., reflective coating).
- Locking Mechanism: Depending on the specific design, the manhole cover may have a locking mechanism to prevent unauthorized access or tampering. This can include features like keyholes, bolt-down mechanisms, or security locks.
- Weight: The weight of the manhole cover can vary depending on the design and size, but it is typically heavy to withstand the specified load rating. Ductile iron manhole covers are generally heavier than their cast iron counterparts due to their higher strength.
- Installation: Ductile iron manhole covers are typically installed by placing them over the manhole opening and securing them in place using appropriate fasteners or locking mechanisms. They may also require bedding and backfill materials to ensure stability and prevent movement or shifting.
- Applications: Ductile iron manhole covers with a D400 load rating and a 600mm opening size are commonly used in heavy-duty applications, such as roads, highways, airports, and areas with heavy vehicular traffic. They are designed to withstand the weight and pressure exerted by large vehicles, ensuring safety and durability.
