These manhole covers are primarily made of ductile iron (SG iron) or nodular iron a unique form of iron. Depending on the nodularity, the quality of the iron is determined whether it is good or bad. Ductile iron covers are known for their solidness, strength, heavy-duty, and resilient features. Ductile iron will not corrode as quickly as cast iron, as the manhole cover manufactures spray anti-rust asphalt paint at the surface of the covers. The loading classes for ductile iron manhole covers are subjected to BS EN 124:2015 guidelines and are predominantly used over a D400 class.
One of the most significant roles of storm drain covers is to prevent flooding. By efficiently channeling rainwater away from streets, homes, and businesses, these covers mitigate the risk of water accumulation during heavy storms. Flooding can cause extensive damage to property, disrupt daily life, and pose safety risks to residents and drivers. Properly functioning storm drain systems help alleviate these dangers by directing excess water to treatment facilities where it can be managed effectively.
