Characteristics

Beautiful appearance: the lines are simple. Silver _ glass reinforced plastic cover _ appearance.

Drainage: The leakage area is 83.3%, which is more than twice the drainage of cast iron.

Hot dip galvanizing: strong rust resistance, free of maintenance and replacement. _ _ FRP cover _ pirate design: FRP cover and frame with hinge connection, anti-glass reinforced plastic cover _ thief, An _ glass reinforced plastic cover _ full, convenient to open.

Save on investment: big span. Its load-bearing load is lower than the price of cast iron, saving the cost of stolen or crushed replacement.

High strength: strength and toughness are much higher than cast iron, can be used for _FRP cover _ dock, airport and other large span and heavy load living environment.

performance

1, outstanding wear-resistant anti-skid performance: anti-slip and wear-resistant treatment will be carried out during the production process. Its anti-slip and wear resistance are far superior to other metal cover plates and wooden cover plates and plastic cover plates.

2, good sealing performance, high safety: and very poor corrosion resistance

Compared with the metal cover plate and the poorly-formed wooden cover plate, the sealing performance of the FRP cover plate is first-class. It has many characteristics of non-conductivity, non-conductivity and high corrosion resistance.

3, high temperature resistance,

High flame retardant performance: All FRP products have strong flame retardant properties, mainly due to the raw material-resin made of FRP. Although the types of resins are different, they can be classified into many types, but high temperature resistance is one of the special properties necessary for each resin.

4, excellent resistance to aging, corrosion resistance: aging is also a manifestation of corrosion, more accurately can be expressed as chronic _ glass reinforced plastic cover _ corrosion, such as humid air is a chronic corrosive environment. The metal cover is slowly corroded when placed in humid air for a long time, which is commonly known as rust.

5, its long service life, high economic efficiency: In general, the service life of FRP cover can be more than 50 years. The service life of some metal covers is only about 5 years and the service life of wooden covers is only 3

specification

The specifications of the FRP cover are the same as those of the FRP grille, but only 2mm in size. For example, FRP gratings are available in sizes 25/30/38/50/60/70, while FRP covers are available in sizes 27/32/40/52/62/72. The color of the FRP cover can also be set _ FRP cover _ to match the color of different colors _ glass reinforced plastic cover _ pulp, according to the needs.
