Currently, the manhole covers that are widely available on the market are cast iron manhole covers and composite manhole covers. Then which is better, cast iron vs composite manhole covers? We will discuss it in this article.
Many drainage holes have appeared in the surrounding environment as urbanization develops. Manhole covers can be seen anywhere from roads, airports, sidewalks, bridges, and anywhere else. The use of manhole covers not only helps workers maintain the drainage system but can also help the safety of pedestrians or the general public when crossing drainage channels.
Cast Iron manhole covers are drainage components made of cast iron with the primary function of covering manholes in drainage channels. There are those who use ordinary cast iron, there are also those who use high-end cast iron. The ductile iron manhole cover uses high-end cast iron material and is a high-strength cast iron material.
In the last ten years, composite manhole covers have become very popular. This material has the advantage of being corrosion-resistant and there is no risk of rust because it does not contain metal. Apart from that, there is also no risk of theft. Composite manhole covers are also lighter than metal manhole covers. This can save costs, maintenance, handling, and dismantling are also easier and more convenient.
There are several reasons why composite manhole covers are a better choice, including:
1. The problem generally faced by metal manhole covers is that they are prone to theft, causing losses. Apart from that, it also increases labor costs.
2. Metal manhole covers are generally very heavy so it is quite difficult to carry the manhole cover during the installation, dismantling, and maintenance process.
3. Metal manhole covers increase the risk of electric shock. To date, quite a number of cases have occurred due to electric shocks on metal manhole covers.
Another advantage of composite manhole covers is that they have perfect anti-slip and airtight properties. Composite manhole covers are also available in various colors so that the view can be far from boring and beautiful.
Both metal manhole covers and composite manhole covers both have good quality. The choice of both can be adjusted to suit your needs. So, between cast iron manhole covers vs composite manhole covers which one will you choose to cover the drainage holes?
