Which type of manhole cover is more suitable for use in rainy areas?
Resin manhole cover
Strong corrosion resistance: The main component of the resin manhole cover is a polymer composite material, such as unsaturated polyester resin, which has high chemical stability. It is not easy to corrode and rust in an environment with long-term contact with rainwater. It has a long service life and can effectively reduce the damage and replacement frequency of manhole covers caused by corrosion.
Light weight and easy maintenance: Its weight is only about one-third of that of cast iron manhole covers. In rainy seasons, when drainage wells need to be frequently inspected and cleaned, resin manhole covers are easier to carry and operate manually, reducing the difficulty and labor intensity of maintenance work.
Good anti-slip performance: The surface of the manhole cover can be designed with anti-slip textures, which can be used in rainy seasons. In the case of slippery weather or slippery roads, it can provide better friction for pedestrians and vehicles, effectively preventing slips and traffic accidents.
Aesthetics and environmental coordination: Resin manhole covers can be customized according to different usage scenarios and needs, with rich colors and beautiful appearance, which can better integrate into the urban landscape and surrounding environment, and enhance the overall aesthetics of the city.
Insulation: Resin materials have good insulation properties. In rainy and humid environments, they can avoid safety hazards caused by leakage and other problems. They are especially suitable for manhole cover areas with electrical equipment or lines.
Cast iron manhole covers
High strength and strong load-bearing capacity ： Cast iron manhole covers, especially ductile iron manhole covers, have high strength and toughness, outstanding load-bearing capacity, can withstand frequent rolling of heavy vehicles, and are not prone to deformation, cracking and other problems. They are suitable for roads and places with heavy traffic and heavy loads in rainy areas, such as urban main roads and highways.
Good stability: The self-weight of cast iron manhole covers is large, and the stability is high after installation. Under the impact of water flow or other external forces, it is not easy to shift or loosen, which can ensure that the manhole covers always maintain a good covering state in the rainy season and ensure the safety of pedestrians and vehicles.
Strong impact resistance: In rainy areas, there may be branches, debris, Objects and other objects impact the manhole cover with the water flow. Cast iron manhole covers can withstand a certain degree of external force impact due to their good impact resistance, reducing the risk of manhole covers being damaged.
Long service life: Although cast iron manhole covers are prone to rust in humid environments, after anti-corrosion treatment such as spraying anti-rust paint on the surface, their service life is still long, which can meet the needs of long-term use in rainy areas.
Recycling value: Cast iron manhole covers have a certain recycling value, which may increase the risk of theft to a certain extent, but it also means that after the manhole cover reaches its service life, it can be recycled and reused, which has certain environmental and economic value.
