Jinmeng has participated in several National Standards for manhole covers and Smart City and obtained Italian ICMQ, British UKAS, ISO9000, ISO14000 and other system certifications.


The standard Sewer Covers and Manhole Covers for Vehicles and Pedestrians.
It is molded from an exclusive patented material and equipped with a long fiber structure, which is sturdy and durable, with stronger compression resistance, and the highest test load is 900KN (90 tons)
FRP has extremely high resistance to concentrations of acids, alkalis, salts, and a variety of oils and solvents; 
Compared with cast iron manhole covers and cement reinforced manhole covers, the weight is lighter. Easy for the construction and maintenance, while greatly reducing transportation costs.
1. The natural properties of SMC material make it have no recycling value, and prevent traffic accidents and road safety hazards caused by theft.
2. The simple and innovative anti-theft system design concept enables the manhole cover to be opened only by a specially designed key, which greatly improves the safety.
The product has good anti-static performance, which eliminates the potential safety hazards caused by static electricity, and has good insulation. It is widely used in gas stations and other oil gas industries.


What is SMC ?

SMC (sheet molding composite) is the most standard fabrication form of FRP production, those 3+mm sheets are mainly composed of polymer resin, calcium carbonate, fiberglass, and some chemical materials. 

What is SMC Manhole Cover?

SMC manhole cover is a sort of composite cover, The cover shares the same loading class as the iron cover does. It is corrosion-free and eco-friendly, is considered as a replacement for iron covers for anti-thieft and safety purposes.

Why Choose SMC Manhole Cover ?

With the help of the natural advantages of raw materials and continuous improvement of production technology, Jinmeng composite manhole covers have good impact resistance, bending strength, high friction resistance, noise resistance, high corrosion resistance, longer service life, and lighter weight, and are easy to install. It has no recycling value due to raw material characteristics. 
At the same time, combining with the Jinmeng anti-theft lock system and waterproof & noise-reduction technology developed by the company's R&D center, Jinmeng SMC manhole cover is more technical and has better practicability and generalization which perfectly solved the traditional cast iron manhole cover’s theft problem. 
SMC material has obvious advantages in tensile resistance, bending performance and flexible structural design performance, and is currently the most ideal composite manhole cover material. Compared with BMC reinforced steel manhole cover, magnesite material manhole cover and other composite manhole cover, Jinmeng SMC manhole cover performed much better at loading test and makes the road safer. 
Jinmeng fabricates composite manhole covers, trench covers, Trench drain grates, customized composite valve boxes, manhole chambers.
