  • Because of their aerodynamic design, some modern racing cars create enough vacuum to lift a manhole cover off its recess. During races on city streets, manhole covers must therefore be welded or locked down to prevent injury. In 1990, during the Group C World Sportscar Championship race at Circuit Gilles Villeneuve (located in a public park in Montreal, Quebec), a Brun Motorsport Porsche 962 struck a manhole cover that was lifted by the ground effect of the car he was following, a Courage C24 Porsche. This caused the trailing Porsche to catch fire, and safety issues ended the race shortly afterwards.[citation needed]

  • 1. Material Type The type of steel used significantly affects the performance of the grating. Carbon steel is ideal for general usage, while stainless steel is preferred in corrosive environments due to its resistance to oxidation and rust. Aluminum grating is lightweight and resistant to corrosion, making it suitable for marine applications.


  • Additionally, iron tree grates play a significant role in managing urban runoff and reducing the heat island effect in cities. By allowing rainwater to filter through the grate to the tree roots, they contribute to effective stormwater management. Healthy trees, in turn, contribute to better air quality, provide shade, and foster biodiversity—benefits that are increasingly crucial in urban planning amid climate change.

  • As manhole manufacturers, we often get asked about the purpose of manholes and the uses of manholes. And the answer is, that there are many functions of manholes when it comes to sewer or stormwater systems. The four main purposes of a manhole are:

  • In urban environments, we often take for granted the intricate network that sustains our daily lives. Hidden beneath the bustling streets are systems and structures that operate silently yet efficiently. Among these, manholes serve as crucial access points to the subterranean world, providing entry to the labyrinth of water, sewage, electricity, and telecommunications that power our cities. However, it's not just the manhole itself that intrigues, but also the steps that lead into the depths below.


  • Cast iron  manhole covers are preferred because they are strong, cheap and easy to cast. A heavy  manhole cover is essential to ensure that the cover does not get dislodged by pressure from gasses released in the drains and also from sucking pressure of fast moving vehicles. Unpainted cast iron inherently possesses rust resisting properties that make it an excellent choice to ensure best performance and long service life. Though other materials for manhole covers are available, the strength of cast iron cannot be overstated when it comes to resisting earth and pavement pressures.

  • In conclusion, drain channels are an essential investment for any driveway, ensuring effective water management, enhanced safety, and prolonging the life of the driveway. By understanding the importance of proper drainage and choosing the right system, property owners can protect their investments and maintain an attractive and functional exterior.


  • Other manhole shapes can be found, usually squares or rectangles. For example, in the United Kingdom nearly all manhole covers are square or rectangular and very occasionally triangular, but almost never circular. Nashua, New Hampshire, is unusual for having triangular manhole covers that point in the direction of the underlying flow. In 2011, the city began gradually phasing out the triangles,[9] which were made by a local foundry, because they were not large enough to meet modern safety standards and a manufacturer for larger triangles could not be found.[10] Some manhole covers in Hamilton, Bermuda, are triangular, and hinged. Some triangular water-main covers also exist in San Francisco.[11]
