Common Types and Applications of FRP Covered Gratings

  • FRP trench cover

Its function is superior, it has the characteristics of light weight, high strength, and high wear resistance. The appearance of the FRP trench cover will be treated with a certain slip and wear resistance.

  • FRP cable trench cover

FRP cable trench cover is also classified as a kind of FRP trench cover, but its production requirements are relatively high compared with the general trench cover. Non-conductivity is the first requirement, and the sealing requirement is higher.

  • FRP grating cover

The scope of application of FRP grating cover is smaller than the FRP trench cover and FRP cable trench cover. FRP grating cover with one more manufacturing process can be easily replaced by the normal FRP grating. For example, the FRP grating cover of swimming pool and walkway.

Optional resin type of Mach’s Composite FRP covered gratings:

There are three commonly used resin types for FRP covered gratings: orthophthalic, isophthalic and vinyl. Its price is directly proportional to its ability to resist corrosion, so according to the corrosive medium of the application environment, query the function introduction and corrosion resistance function table to select the most economical resin type.

A. Orthophthalic type: It has general corrosion resistance, resistance to atmospheric aging, seawater corrosion, etc., long-term use temperature -50-60 ℃.

B. Isophthalic type (for municipal use): It has excellent corrosion resistance, which can withstand medium-concentration inorganic acids and alkalis, various salts and other environments, and has a long-term use temperature of -50-90 ℃.

C. Vinyl type (for chemical use): It has excellent corrosion resistance, which can withstand acid, alkali, salt, solvent, or acid-base replacement and other harsh corrosive environments, and has a long-term use temperature of -50-110 ℃.
