AvailableProduct Introduction
Manufactured for unparalleled resilience, our premium 300x1000mm rectangular drainage covers are expertly cast from high-grade ductile iron to withstand the most demanding infrastructural environments. The underside is strategically reinforced with a robust ribbed structure that efficiently distributes massive dynamic loads, preventing deformation or structural failure under continuous heavy traffic. Furthermore, the meticulously designed raised surface pattern ensures excellent skid resistance, safeguarding both pedestrians and industrial vehicles in adverse weather conditions. As an experienced foundry, we deliver these high-performance municipal castings to provide global contractors with a dependable, long-lasting, and virtually maintenance-free infrastructure solution.

Product Specification
Designed for extreme engineering conditions, our heavy-duty rectangular manhole covers (300x1000mm) offer maximum security for high-risk zones. Below is the detailed technical data for our F900 ductile iron castings.
• Material: High-Grade Ductile Iron (Nodular Cast Iron GGG50 / QT500-7)
• Standard: BS EN 124-2
• Load Class: F900 (Up to 900kN / 90 Tons)
• Dimensions: 300x1000mm (Rectangular Trench / Drainage Cover)
• Surface Treatment: Black Bitumen Coating (Anti-corrosion and rust-resistant)
• Features: Heavy-duty ribbed underside, anti-slip raised pattern, extreme impact resistance
Product Advantages
Engineered to meet the stringent EN124 F900 standard, this cover withstands up to 900kN (90 tons) of dynamic load. It is the ultimate choice for extreme high-stress areas such as airport runways, commercial seaports, and heavy industrial facilities.
Cast from premium GGG50 ductile iron, it offers exceptional tensile strength and elongation. Unlike traditional grey cast iron, it bends rather than shatters under sudden extreme impacts, significantly enhancing the safety margin for heavy-traffic zones.
The back of the 300x1000mm cover is reinforced with a scientifically designed ribbed grid. This matrix evenly distributes massive vehicle weights, ensuring long-term structural integrity and preventing warping or deformation over decades of use.
The meticulously engineered raised square patterns on the surface maximize tire traction and pedestrian grip. This effectively prevents skidding accidents during heavy rainfall or in harsh, oil-prone industrial environments.
Finished with a high-quality black bitumen coating, the ductile iron casting is highly resistant to rust and chemical degradation, guaranteeing a virtually maintenance-free infrastructure solution for global contractors.
FAQ
Q: Where is an EN124 F900 load class rectangular manhole cover typically used?
A: F900 is the highest load class defined by the EN124 standard, capable of withstanding up to 900kN. These heavy-duty 300x1000mm trench covers are strictly designed for areas subjected to extreme wheel loads, such as airport runways, aircraft taxiways, commercial seaports, and heavy industrial machinery facilities.
Q: Why should we choose ductile iron over traditional grey cast iron for trench covers?
A: Ductile iron (nodular cast iron) possesses a unique microstructure that offers superior tensile strength and impact resistance. Unlike grey cast iron which is brittle and can shatter under sudden heavy impacts, ductile iron will safely flex or bend under extreme stress, providing a critical safety margin for high-traffic infrastructure.
Q: Can the 300x1000mm ductile iron cover be customized for specific engineering projects?
A: Yes. As an experienced source manufacturer, FL Manhole Cover provides comprehensive OEM/ODM services. We can customize the surface anti-slip patterns, integrate secure locking mechanisms/hinges to prevent theft or dislodgement, and cast custom agency or corporate logos directly onto the cover to meet your specific municipal or private project requirements.
