Product Overview

Double Sealed Ductile Iron Manhole Cover is designed for EN124 road drainage, municipal utility access, sewer systems, sidewalks, parking areas, and urban infrastructure projects where odor control, noise reduction, and stable cover-frame fitting are required.

This double sealed manhole cover uses a reinforced ductile iron cover and frame structure to improve installation stability and daily performance. Compared with standard manhole covers, the double sealing design helps reduce odor escape from underground drainage systems, minimize vibration noise caused by traffic movement, and improve the fitting between the cover and frame.

The product can be supplied according to EN124-2 load class requirements, including B125, C250, D400, or customized project specifications. Hongke supports custom sizes, surface patterns, frame designs, logos, coatings, and packaging for municipal engineering, road construction, drainage projects, and utility access applications.

Why Choose a Double Sealed Manhole Cover?

A double sealed manhole cover is a practical solution for projects that require better odor control, reduced road noise, and more stable installation. The improved sealing and cover-frame fitting help reduce unwanted movement when vehicles pass over the cover, making it suitable for roads, parking areas, drainage systems, and municipal utility access points.

For urban infrastructure projects, sealed manhole covers can help improve the surrounding environment by reducing odor escape from underground sewer or drainage systems. They also help improve daily road performance in areas with frequent vehicle movement.
