Ductile Covers

Ductile Iron Manhole Covers

Ductile Iron Manhole Covers provide secure access to underground drainage and utility networks in applications ranging from footpaths to heavily trafficked roads. The range includes covers and frames in B125, C250, and D400 load classes, allowing contractors and engineers to select the appropriate cover for the installation environment and traffic loading requirements.

Choosing the Right Load Class

The most important consideration when selecting a ductile iron manhole cover is the load class.

B125 covers suit footpaths, pedestrian areas, private driveways, and locations with occasional light vehicle traffic.

C250 covers are designed for areas such as car parks, kerbside locations, and commercial environments where slow-moving vehicles are present.

D400 covers are suitable for roads, industrial sites, and other locations exposed to regular vehicle traffic and higher wheel loads.

Selecting the correct load class helps ensure compliance, safety, and long-term performance.

Why Ductile Iron Is Widely Specified

Ductile iron has become the preferred material for many manhole cover applications because it delivers high load capacity without excessive weight. Its strength and resistance to impact make it suitable for environments exposed to regular vehicle traffic, while its durability helps support long service life in demanding conditions.

Installation Products
