We often use manhole cover in road construction, and there are many kinds of manhole cover materials, such as cast iron, composite, plastic, cement and so on.
At present, there are plastic manhole covers on the market, especially in Pakistan, but the disadvantages of plastic manhole covers are that the load is too small, easy to break, and easy to aging.So people are looking for a new material to make up for the shortcomings of plastic manhole covers, so BMC and SMC compound manhole covers have been widely popular in China.
Not only did they solve the problem of heavy weight of cast iron manhole covers, but also the price was very cheap. So this kind of well cover is becoming popular in some foreign countries, such as DUBAI, Oman,India,etc..
What does the composite manhole cover look like?
Why Choose BMC or SMC Composite manhole cover ?
ADVANTAGES OF BMC Plastic manhole cover
High load rating and strength for BMC Plastic manhole cover
Similar hard property as cast iron, while have a overwhelming advantage on stretch recovery.
Designed to meet and exceed A15/B125/C250/D400 loading rating, according to En124: 1994.
Solidity and resistance for BMC plastic manhole cover
Our manhole cover is fabricated in compliance with EN 124 standard. Performance tests, locking system and other devices are guarantee of safety and strength.
Available in different sizes, it is suitable for the same applications of products made of trditional materials with equivalent or higher performances.
Electric insulation for BMC manhole cover
Our BMC manhole cover made of composite material is particularly suitable for installation in pedestrian areas as it protects pedestrians against voltage dispersion, especially in moist and wet environments, considering that composite material is not electrical-conductive.
Noise reduction
The advantage of using the Hongda cover, compared to the cast iron covers, is noise reduction in pedestrain and traffic areas.
The material and sealings used for installation make it suitable for the reduction and of smell release in the environment.
Environment protection
Dubai belongs to the United Arab Emirates and is the most populous city in the United Arab Emirates. In Dubai’s road construction, manhole covers are often needed, and many manhole covers are imported from China, and they generally like manhole covers with pull rings. This kind of manhole cover is more convenient to lift.

BMC(DMC) is the abbreviation of “bulk/dough moulding compounds”.it is often domesticly called“unsaturated polyester molding compound”.Its principal raw material is group of presoak material fully mixed with GF(chopped glass fiber),UP(unsaturated resin),MD(filler),and various of additives. DMC materials were first applied in the former west germany and the UK in 1960s and developed greatly in the United States in 1970S and Japan in 1980S.The Bmc Is increasingly welcomed by the masses of users for its excellent electrical and mechanical properties,strong heat resistance,good chemical corrosion resistance and can be easily adapted to a variety of molding process,which meets the users’ requirement on the properties of various products.
