The square manhole composite cover is manufactured according to the EN124 standard, which is lighter than the traditional manhole cover, which greatly reduces the transportation cost. It has high strength, aging resistance, high temperature resistance, good wave transmission performance and antistatic performance.
Jinmeng products meet the national standard GB/T 23858-2009, European standard EN124-5:2015, American standard AASHTO, Australian standard AS3996 and has been developing to the direction of high-performance, multi-functioning, intelligence. Covers and composite products have been exported to more than 80 countries and won global reputation. Jinmeng is Chinese top manhole cover manufacturer and won the "Zhejiang Famous Brand" honor.Jinmeng has participated in several National Standards for manhole covers and Smart City and obtained Italian ICMQ, British UKAS, ISO9000, ISO14000 certifications.
Composite materials have no recycling value, and compared with cast iron manhole covers, the chance of being stolen is greatly reduced.
The weight of the product is much lighter than cast iron, which greatly reduces the damage to the human spine and fingers during the installation process, and the surface has a good anti-slip design.
Unlike cast iron that blocks electromagnetic waves, SMC has good wave-transmitting performance, and the communication signals in the well can be directly transmitted to the ground base station through the SMC manhole cover. SMC materials have been widely used in fields such as smart manhole covers and 5G radomes.
