In terms of sewage treatment, the FRP grating can be used as a filling material for the operating platform below the cooling tower, or as an inspection aisle for the sewage treatment plant.

In the sewage treatment system, a large number of guardrails and a FRP grating as an aisle plate are required around the water treatment tank. In traditional engineering, the guardrail and the FRP grating are made of metal materials, such as steel pipes, and the surface is coated with anti-rust paint. Many of the treated sewages are strongly corrosive, and the splashed water droplets or volatilized water vapor have a strong corrosive effect on the metal parts. Over time, these metal parts are rusty and even damaged. Many hidden dangers.

Compared with metal profiles, FRP gratings have light weight; high strength; excellent corrosion resistance, which can fundamentally solve the problems of corrosion and difficult maintenance of metal guardrails and FRP grids, and greatly extend the service life and comprehensive cost. Controlled; beautiful in appearance and color, and can maintain a bright color in a corrosive environment, which can beautify the environment.
