In today’s fast-growing cities—from India’s smart infrastructure projects to highways in the UK, Europe, the Gulf, and the USA—choosing the right manhole covers isn’t just a technical decision, it’s a safety and performance necessity.
Whether you’re working on drainage solutions, water solutions, or road infrastructure, selecting the correct EN124 load class ensures durability, safety, and long-term cost efficiency.
At Ultra Tech Foundry (UTF), we combine engineering expertise with global standards—“Making the quality by experience & science.”
What is EN124 Standard?
The EN124 standard is a European specification that defines load-bearing classes for manhole covers, gratings, and recessed manhole covers used in infrastructure projects.
It helps engineers, contractors, and procurement teams choose the right product based on traffic conditions and load requirements.
EN124 Load Classes:
Here’s a simplified breakdown of EN124 classifications and where they are used:
A15 – Light Duty (Up to 1.5 Tonnes)
- Application: Pedestrian zones, gardens, walkways
- Ideal for light-duty water solutions
- Not suitable for vehicular traffic
B125 – Medium Duty (Up to 12.5 Tonnes)
- Application: Footpaths, parking areas, residential zones
- Common in urban drainage solutions
- Used with gratings and small access covers
C250 – Heavy Duty (Up to 25 Tonnes)
- Application: Roadside gutters, kerbside drainage
- Frequently used with recessed manhole covers
- Ideal for areas with moderate traffic
D400 – Extra Heavy Duty (Up to 40 Tonnes)
- Application: Main roads, highways, industrial zones
- Most commonly used ductile iron manhole covers class
- Essential for high-load drainage solutions
E600 & F900 – Extreme Load Conditions
- Application: Airports, docks, heavy industrial zones
- Designed for extreme loads and specialized infrastructure
Why Choosing the Right Load Class Matters
Selecting the wrong manhole cover can lead to:
- Structural failure
- Safety hazards
- Increased maintenance costs
- Non-compliance with global standards
For international projects—especially in Europe, UK, Gulf countries, and the USA—EN124 compliance is often mandatory.
Why Ductile Iron Manhole Covers Are the Best Choice
When it comes to performance, ductile iron manhole covers stand out across all EN124 classes.
Key Advantages:
- High tensile strength
- Impact resistance for heavy traffic
- Long service life
- Anti-theft and corrosion-resistant designs
UTF specializes in manufacturing precision-engineered ductile iron castings, ensuring reliability in every project.
