Manholes, also known as utility holes, maintenance holes or sewer holes, serve as an opening to the sewage system or other confined spaces.
Manhole covers and frames are made of long lasting and resilient materials such as cast iron, galvanised steel or plastic. Cast iron manhole covers and frames are suitable for places with frequent traffic and heavyweight vehicles. Galvanised steel manhole covers and frames are advisable for slow-moving traffic or pedestrians. Plastic manhole covers and frames are ideal for installing garden drain covers.
If you are looking for a reliable, yet aesthetically pleasing type of a manhole cover, opt for a recessed manhole cover. This type of manhole cover has a metal tray, enabling the paving of slabs, blocks or screed.
