Difference between FRP grille cover plate and metal grille cover plate

The difference between Linsen FRP grille and steel grating cover plate is as follows:

1, with different appearance.

The difference in appearance is the most obvious difference between the two. The FRP cover plate is mainly solid, or hollow in the middle, or hollow in the middle, but its surface is solid and closed. Generally speaking, the FRP cover plate is a closed plate. The appearance of FRP grille cover plate is based on the grille plate and the cover plate is the bearing surface. As a matrix, the grid plate is not a single type, but can be straight grid, standard grid and convex grid. There is no big difference between the surface cover plate and the FRP cover plate.

2, the production process is different

In the manufacturing process, the FRP grille cover plate is much more troublesome than the FRP cover plate. Firstly, the grid plate is formed, and then the cover plate is pasted by hand. The latter only needs a manual pasting process. The main reason is that the raw materials are different. The glass fiber reinforced plastic cover plate is mainly made of glass fiber felt and resin, while the glass fiber reinforced plastic grid cover plate is mainly made of glass fiber yarn and resin.

3, the performance is different

The disadvantage of FRP cover plate is that it is bulky and inconvenient to carry and install. The disadvantage of FRP grid cover plate is that the surface area of the cover plate should not be too large when it is put into use, which may easily lead to the separation of the cover plate from the grid plate. But both of them have many advantages, such as high acid and alkali resistance, corrosion resistance, high temperature resistance, aging resistance, high flame retardancy, non-conductivity, non-thermal conductivity, long service life and so on.

4. Different uses

Relatively speaking, FRP grille covers are widely used, such as ditch cover plate, gutter cover, cable ditch cover plate, sewer ditch cover plate, manhole cover and pool cover. The application scope of FRP cover plate is limited to narrow space.
