Watertight Sealed Manhole Cover

Manufactured per EN124 standards, our sealed ductile iron manhole covers feature six optional load grades from A15 to F900 for diverse road applications. Finishing choices include bitumen coating and black anti-rust paint. Fitted with embedded rubber seals, the covers are available in round, square and rectangular shapes, with both standard sizes and custom dimensions per client drawings supported.

The built-in rubber seal delivers excellent waterproof and odor-proof performance to stop rainwater infiltration and pipeline odor escape. Anti-slip textured surfaces enhance pedestrian safety on wet days. A built-in anti-theft lock firmly secures the cover in place to prevent loss and theft. The premium surface coating provides superior wear and corrosion resistance for long-term outdoor service.

Made of high-strength ductile iron, the manhole cover boasts exceptional pressure and impact resistance, resisting cracking and deformation under long-term heavy vehicle loads. Versatile load grades adapt to sidewalks, parking lots and heavy-duty road scenarios. Flexible customization on shape, size and surface treatment meets personalized project needs, while stable factory production guarantees fast bulk order delivery.

Adopting premium EN-GJS-5007 ductile iron, the product features high tensile strength and stable structural performance. It withstands continuous heavy pressure without structural damage. The professional bitumen coating insulates the metal from sewage, rain and harsh outdoor environments, inhibiting rust and corrosion and lowering long-term maintenance expenses
