Custom cast iron manhole cover
Our custom cast iron manhole covers are manufactured to meet international standards including EN124, providing reliable performance for municipal, industrial, and infrastructure applications. Available in ductile iron and grey iron, our manhole covers support load classes from A15 to F900, covering pedestrian walkways through to heavy highway traffic zones. OEM, ODM, and custom logo casting are all supported with flexible MOQ.
Our cast iron manhole covers are widely used in:
- Municipal roads and urban drainage systems
- Highways and heavy traffic zones
- Airports and industrial plants
- Telecommunications and electrical utility access
- Stormwater and sewer infrastructure projects

Introduction
Why Choose Our Cast Iron Manhole Covers?
Multiple Load Classes Available — From A15 (pedestrian areas) to F900 (aircraft pavements), we manufacture to your specified load requirement, ensuring the right cover for every application.
EN124 & ISO Certified — All manhole covers are produced under ISO 9001 quality management and can be manufactured to EN124, BS EN124, or customer-specified standards.
Custom Size & Logo Casting — Frame diameter, clear opening size, surface pattern, and even your company logo or municipal branding can be cast directly into the cover during production.
Ductile Iron & Grey Iron Options — Ductile iron offers higher impact resistance and longer service life, while grey iron remains a cost-effective choice for lighter load applications.
Anti-Theft & Anti-Noise Design — Optional locking mechanisms and rubber gaskets available to prevent theft and eliminate rattling noise under traffic load.
