Standard Round Manhole Made of Ductile Iron

The ductile iron round manhole is made of high-strength cast iron, specially designed for municipal projects, road drainage, and water supply systems. Its size and load-bearing capacity (B125–E600) are suitable for a wide range of applications, meeting various load requirements. It is particularly ideal for use on city roads, residential areas, and industrial zones.

Key Features:

• High-Quality Cast Iron: Made from high-strength iron with excellent compressive strength, ensuring the manhole cover can withstand high loads over long-term use without damage or deformation due to overloading.

• Wide Applicability: Compatible with base sizes ranging from 300mm to 1000mm, making it suitable for various engineering requirements while ensuring flexibility and adaptability.

• Excellent Durability: The cast iron material not only provides exceptional load capacity but also resists long-term wear and corrosion, maintaining the cover’s stability and safety over time.

• Custom Lettering: Lettering on the manhole cover can be customized according to customer requirements, making it ideal for project-specific identification and management. For example: “Ninghai County Water Supply Group – Hotline: 65550018” can be tailored as needed.

• Anti-Corrosion Treatment: The manhole cover surface undergoes fine machining and anti-corrosion treatment, effectively enhancing durability, preventing rust and corrosion, and ensuring stable performance in harsh environments.

Applications:

This ductile iron round manhole is widely used in municipal construction, road traffic systems, drainage networks, and water supply pipelines. It is especially suitable for high-load areas such as commercial zones, industrial parks, residential areas, and traffic-intensive roads. Its reliability and durability make it a crucial component in ensuring the safe operation of municipal infrastructure.
