The BMC sewage cover adopts short glass fiber as the main material, and reinforcement is used to enhance the load. The reinforcement belongs to metal material, which is different from the bending coefficient of composite material, so for a long time, the reinforcement and material inside will also be separated. In addition, the bearing capacity of BMC well cover is relatively low, which can only be used in low load areas such as green belt, sidewalk, non motor vehicle lane, etc.
SMC manhole cover is made of continuous long glass fiber reinforced material. After high temperature molding, without reinforcement, the load can meet the requirements of the national standard. It is suitable for gas stations, large-scale agricultural markets, freight stations, wharves, logistics parks and other places.
