SMC Material Composite Manhole Cover En124 D400

High load performance
Jinmeng composite manhole covers with robust monolithic structure will not delaminate, which determines its high loading capacity, meeting and exceeding A15/B125/C250/D400/E600 loading rating, according to BS EN124: 1994, certificated by BSI, BV, Eurofins, etc.

Theft aversion & security
Jinmeng composite manhole covers have no resale value and cannot be sold as scrap. Applying the Jinmeng special lock device makes the road safer.

Lightness and handiness
Jinmeng composite covers are 30% lighter than steel or iron's weight under the same load rating. One of the benefits is easy to remove and replace. This quality fitted with a special ergonomic lifting tool eliminates the risk of the installer's injury.

Long, durable service life
Jinmeng composite manhole covers continue to perform well even after 30 years in service.

Customization
Covers can be designed with the agency's logo and an inscription printed on the front side. There is also the possibility of producing covers and/or frames in different colors so as to identify specific services or offer aesthetical value to the laying of covers and surroundings.

Less cost of transportation, installation and usage
1. The lightweight of each single cover also reflects a considerable reduction in transport expenses.

2. Compared with composite material, the service life of an iron manhole cover is about 8 years and needs more cost of manpower and installation ( requires more than two installers) with potential injury and defects of being vulnerable to being stolen or replaced.

3. Under normal traffic conditions and suitable installation (requires only one installer), the service life of the Jinmeng composite manhole cover is 30 years and will not break, or corrode, which also means free maintenance and zero cost of replacement throughout the life cycle. So the composite manhole cover is a better choice.

High solidity and stability
Frame with reinforcing ribs design ensures that the surrounding concrete structure cements with the frame firmly, which prevents displacement and cracking, unlike concrete and BMC, Jinmeng composite manhole cover will not crumble or crack. Jinmeng composite manhole cover also has the advantage of high stability, for example:
1. Non-conducting
2. Athermic
3. Chemical inertness
4. Having a proper functioning under extremely bad weather (-40 degree-200 degree)
5. Anti-UV
6. Friction resisting

Anti-slip design
Unique anti-slip surface design with varieties of tread types of Jinmeng has good performance of slip-resistance in ensuring pedestrians and vehicles safely in wet or some extreme weather.

Shockproof and waterproof
Rubber sealing between cover and frame enhances the frame's wearing property, which reduces noise and friction upon passing of vehicles or persons. Jinmeng also offers a waterproof solution if required. Jinmeng D400 and C250 composite manhole covers can be fully sealed against water.

Environmental friendly
The lower amount of CO2 released in the atmosphere is related to the lower weight of each single cover. Compared with iron manhole cover, loading and transporting on trucks a number of composite manhole covers would have subsequent reduction of pollution due to lower number of transports.
