1. Outstanding wear-resistant and anti-skid performance: anti-slip and wear-resistant treatment will be carried out during the production process. Its anti-slip and wear resistance is far superior to the general metal cover and wooden cover, plastic cover and so on. The anti-slip treatment and wear-resistant treatment of the FRP cover are described in detail in the following sections.

 

2, good sealing performance, high security: compared with the metal cover with poor corrosion resistance, the poor quality of the wooden cover, the closure of the FRP cover is. It has many characteristics of non-conductivity, non-conductivity and high corrosion resistance.

 

3, high temperature resistance, strong flame retardant performance: all FRP products have strong flame retardant properties, the main reason comes from the production of raw materials resin FRP products. Although the types of resins are different, they can be classified into many types, but high temperature resistance is one of the necessary properties of each resin.

 

4, excellent resistance to aging, corrosion resistance: aging is also a manifestation of corrosion, more accurate can be expressed as chronic corrosion, such as humid air is a chronic corrosive environment. When the metal cover is placed in the humid air for a long time, it will be slowly corroded, which is commonly known as rust.

 

5, long service life, high economic efficiency: Under normal circumstances, the service life of FRP cover plate is more than 50 years. The service life of the metal cover is only about 5 years, and the service life of the wooden cover is only about 3 years.
