Round Ductile Iron Manhole Cover D400 EN124‑2 Heavy Duty With Lock Frame For Roadway

Ductile Iron Round Manhole Cover D400 EN124‑2 with Lock and Frame
Our D400 ductile iron manhole cover is manufactured under strict compliance with EN124‑2 European standard. Adopting high‑grade ductile cast iron as raw material, the product combines high tensile strength, outstanding impact resistance and great anti‑corrosion property, which guarantees stable performance even under continuous heavy‑vehicle rolling in harsh outdoor environment.
This heavy‑duty D400 manhole cover can bear maximum test load up to 400KN, designed for locations exposed to heavy traffic such as main roads, highways, urban municipal projects, industrial zones and heavy‑duty driveways. An integrated anti‑theft lock mechanism is equipped to avoid random opening and theft risk, protecting underground pipelines, cables and drainage facilities. The full set includes matching cast iron frame, which ensures good fitting, easy installation and prevents shifting after long‑time use.
The surface is treated with bitumen black painting. This finish effectively resists rust, oxidation and wear, extends product service life and keeps neat appearance in all weather conditions like rain, snow and sunshine.

We provide flexible OEM & ODM customization services. Multiple load classes are optional, covering B125, C250, D400 to fit different road scenarios. We can produce different outer diameter and clear opening sizes according to customer requirements. Custom logo, text marking and special surface treatment are also acceptable. You may send technical drawings or detailed specification for our evaluation.
