Composite manhole covers are solid top access covers manufactured from reinforced composite materials rather than traditional metals such as steel or ductile iron. They are designed to provide durable access to inspection chambers while reducing weight and improving resistance to environmental conditions.
The solid top design features a flat lid that sits within a supporting frame and remains visible once installed. Unlike recessed access covers, the lid does not contain a tray for paving or surface materials, making these covers suitable for straightforward installations where appearance is not required to match the surrounding surface.
One of the main advantages of composite covers is their reduced weight compared to metal alternatives. This can make handling and installation easier, particularly in locations where covers may need to be removed regularly for inspection or maintenance.
Composite materials also provide resistance to corrosion, making these covers suitable for environments exposed to moisture, surface water or chemicals. In addition, the non metallic construction reduces scrap value, which can help limit the risk of theft in certain locations.
Composite solid top covers are used in a range of applications including footpaths, landscaped areas and some driveway installations, depending on the load rating of the cover. Selection should be based on the clear opening required and the expected loading within the installation area.
