Technical FAQ: All About b125 Manhole Cover

Q1: What material is used in manufacturing B125 manhole covers?

B125 manhole cover is typically made from high-strength ductile iron (GGG500-7), approved under EN124 and ISO 1083. This ensures high load-bearing capacity, ductility, impact resistance, and longevity.

Q2: What are the standard sizes available?

B125 covers are available in standard sizes: 300×300, 400×400, 500×500, 600×600, 700×700, 800×800, 900×900, 1000×1000, 1100×1100, and 1200×1200 mm. Custom sizes may be produced on demand.

Q3: What is the EN124 B125 specification?

EN124 classifies manhole covers by load capacity. B125 (Class B125) means the product withstands up to 125 kN (12.5 tons) and is suited for pedestrian areas, sidewalks, and comparable zones.

Q4: Which installation standards must be followed?

Installation should comply with EN124:2015, including: setting the cover flush with finished grade, proper seating of the bottom frame, ensuring anti-slip surface features, and correct bedding.

Q5: Can manhole covers be custom designed for unique projects?

Absolutely, custom manhole covers can be designed for city branding, special size requirements, or enhanced functions (locking, ventilation, anti-theft, colored coatings).

Q6: What is the typical coating used?

Most ductile iron covers are asphaltic coated, giving excellent corrosion resistance and longevity, especially in aggressive environments.

Q7: Do B125 manhole covers support anti-slip designs?

Yes. B125 covers are available with anti-slip surfaces compliant with EN124 Appendices. These increase pedestrian and vehicle safety, particularly in wet or urban areas.
