The composite manhole cover has a long service life. SMC is a polymer composite material, mainly made of high-performance resin, glass fiber and mineral fillers and other reinforcing materials, which can ensure the penetration of resin in the glass fiber and greatly enhance the internal adhesion, so the product can be effectively Load. It has high fatigue strength and frequency under its action, and the service life is usually not less than 30 years.

Composite round manhole cover is non-toxic environmental-friendly products. The reasonable structural design solves the noise problem caused by the impact between the cover and the frame. MR107C suitable for gullytops installed in the area of curbside channels of roads.

Jinmeng composite manhole covers can be used in various applications, such as sewer inspection rooms, telecommunications cables, underground cables, landscaping and roadside intake rooms, etc. The composite manhole covers are available in different sizes and are suitable for the same application of products made of the same or high-performance traditional materials.
JM-MR122A Composite Manhole Cover conforms to BS EN124 A15 Class and is suitable for areas which can only be used by pedestrians and pedal cyclists.

The sealing performance between the composite manhole cover and the frame is better than that of iron products, so there is no noise pollution during use. The wear resistance is good, the use area is more than that of iron products, and the composite material can also transmit radio frequency waves without disturbing data recording.

Heavy duty manhole covers have a longer service life than iron products, and their unit weight is lighter than iron products under the same size and load. Good corrosion resistance, good insulation, and never rust.

The articulated type of SMC round manhole cover is lightweight and can be operated by only one person. The recycled resin material is not used for the second time, so it will not be reused after being stolen. It has good carrying capacity and the strength of steel products, but it has higher toughness and will not brake into fragments.

JM-MR114D-F-IC composite inner cover for JM-MR114-F composite floating manhole cover, to prevent pedestrian falling into the well.
The double cover design is very useful. When the main cover is damaged, the sub cover can also act as a temporary buffer to prevent the risk of falling. There are four leak holes to prevent water from filling up.

JM-MR105-IC composite inner cover is designed for JM-MR105 series manhole cover products, which is used for preventing the people from falling into the manhole.
It has good bearing capacity, high toughness, and improves the safety of the manhole cover.

Lightweight composite manhole covers are extremely durable and lightweight, weighing three times lighter than steel and iron, and four to five times lighter than concrete-so they can be carried by one person, thus avoiding the risk of operator injury. Especially for local governments and public utility companies that are short of funds, this may save huge costs.

The traditional ductile iron manhole covers will wear out over time, especially when it is raining and humid, which poses a serious safety risk to the car and two-wheeler. The structure produced by the composite round manhole cover is many times stronger than traditional metal materials, non-slip, light weight, safe and reliable.
