Depending on the application and requirements of an area, the accessibility and precision of ductile iron manhole covers are defined. However, one crosses by and witness a manhole cover everyday, no one pays attention to the details. The details as to how sturdy, long-lasting, and efficient they are for the required area of application. For the ones who know little about it, let us take a quick look at it.
What are Manhole Covers & why are they important?
Pretty much what the name suggests, Manhole Covers are removable iron, cast iron or ductile iron plates that essentially cover the opening of a manhole to prevent objects and people from falling into it. If you’re installing a new manhole cover or you’re replacing an existing one, measuring the space is key. Finding out the basics of a manhole cover is important to assure a perfect fit and zero-compromise with structural integrity.
What are the different types of Manhole Covers?
Ductile Iron Manhole Cover
Strong, sturdy, resilient and heavy-duty, ductile iron manhole covers are used over a D400 class. The main purpose of using Ductile iron, also known as cast iron, is because of its strength. This type of manhole cover is used to add a long life span to any application. This kind is particularly used for installation in airports, docks, and other heavy-duty industrial areas.
Recessed Manhole Cover
More like a holder or an outline structure, Recessed manhole covers essentially have a cut out in the tray so that bricks, paving bricks, cement, and other pavements can be installed. Since the cover is hardly visible, this allows the recessed manhole cover to blend in with the surroundings. It is useful for pedestrian walkways, side footpaths, etc. It’s also an excellent solution for internalized manhole covers. For example, hospitals, workshops, organisations, and societies.
Solid top Manhole Covers
Places where safety and maintenance need to highlighted, Solid top manhole covers are used for those areas. The idea behind designing these covers is to highlight prominence on a specific floor or a certain area to keep people away from it. These are installed in the areas where one needs to highlight a certain architecture as opposed to hiding it. It is an anti-slip surface where the top is visible or even raised too. The starking contrast between the solid floors and the solid top manhole covers makes them easy to identify.
