Plastic manhole covers

Light weight: Compared with traditional cast iron manhole covers, plastic manhole covers are significantly lighter, such as polyethylene gutter covers weighing only 1/3 or even lighter than cast iron covers, which are easy to transport and install, reducing labor intensity and transportation costs.
Corrosion resistance: It has good chemical stability, can resist the erosion of corrosive media such as acid and alkali, salt spray, and industrial pollutants, and is suitable for corrosive environments such as chemical parks, sewage treatment plants, and coastal areas, with a long service life.

Good insulation: plastic is a poor conductor of electricity, and plastic manhole covers can effectively prevent current conduction, which can avoid safety accidents caused by leakage in places with many electrical equipment, such as electronics factories, substations, mines, etc.

Anti-theft: Plastic manhole covers have a very low waste value and are less attractive to thieves, which can reduce the occurrence of theft and reduce the risk of "urban black hole" accidents caused by missing manhole covers.

Flexible design: It can be molded into various shapes, sizes and colors, and different anti-slip textures can also be designed, such as diamond grille, bump texture, etc., which can not only meet specific use needs, but also beautify the urban environment.

Strong weather resistance: Some plastic manhole covers can withstand temperature changes from -50°C to 80°C, resist UV aging, and perform stably in extreme climatic conditions such as severe cold, heat, and heavy rain.

Low maintenance cost: the surface of the plastic manhole cover is not easy to adhere to dirt, can be cleaned by rinsing with water, and is not easy to rust, no need for anti-rust treatment and repair and other maintenance operations, when partially damaged, the modular design is convenient for single piece replacement, high maintenance efficiency.

Good environmental performance: Some plastic manhole covers are made of recyclable materials, with low production energy consumption, and can be recycled and reprocessed after disposal, which is in line with the concept of green development and reduces environmental pollution.

Good bearing capacity: through scientific and reasonable structural design and the addition of steel skeleton, plastic manhole covers have a certain load-bearing capacity, and some reinforced types can withstand the short-term passage of small cars, which can meet the use needs of sidewalks, squares, non-motorized lanes and other areas.

Sound insulation and noise reduction: When the vehicle is rolled over, the plastic manhole cover produces relatively little noise, which can reduce noise interference to the surrounding environment, especially suitable for noise-sensitive areas such as residential areas.

Types and specifications
Type: According to the use, it can be divided into rainwater plastic manhole covers and sewage plastic manhole covers, etc.; According to the shape, there are common shapes such as round and square.

Application scenarios
Municipal engineering: widely used in urban sidewalks, non-motorized lanes, squares, parks, commercial streets and other places to ensure the normal operation of the drainage system, prevent debris from entering the drainage pipes, and provide a safe and comfortable traffic environment for pedestrians.

Industrial Plant: Suitable for drainage ditch covering in factory workshops, warehouses, parking lots, and other areas, it can withstand frequent crushing by industrial vehicles and machinery and equipment, and resist chemical corrosion generated during the production process.

Garden landscape area: In parks and scenic spots, lakeside paths, water-friendly platforms, hiking trails and other places, different colors and shapes can be customized to integrate with the natural landscape, and at the same time play the function of covering the gutter and anti-slip.

Residential community: used in underground garages, community roads and green areas in residential communities, which can withstand the frequent entry and exit and parking of vehicles, hide the ditch, avoid residents accidentally falling, and improve the quality of the community.
