How can I buy a safe Manhole Cover?
The Composite Manhole Cover is also called a Resin Manhole Cover, an FRP manhole cover, and the like.
The composite manhole cover is made up of unsaturated resin, glass fiber and other materials and steel frame by the special production process, and is molded by high-temperature molding once. The continuous reinforcing fiber yarn is used to ensure that the fiber and the glass fiber are integrated into the material so that the product has sufficient carrying capacity.
The composite manhole cover has become a popular manhole cover in the market due to its resistance to pressure, bending, and impact strength. However, due to the increase in manhole cover manufacturers, the competition has intensified, and the continuous reduction in price and quality has become a means of competition for some manufacturers. A large number of inferior manhole covers have entered the market, and many customers do not have the expertise in this area to distinguish the quality of the manhole cover, which led to deception.
The next four points hope to help customers:
1. Select the manhole cover according to the user's needs and the surrounding environment (must have sufficient carrying capacity)
2. Select the national standard manhole cover manufacturer.
3. The manhole cover installation steps should be reasonable.
4. Do regular inspections and post-maintenance work.
The composite manhole cover is used as a kind of inspection manhole cover, and its characteristics are as follows: the polymer is used as the base material, and the reinforcing material, the filler and the like are added, and the inspection manhole cover is formed by a certain process. The new national standard has increased the load requirements of the manhole cover and is in line with the internationally accepted EN124 standard, which will be implemented from February 1, 2010.
