Before FRP products appeared and occupied the market, grating products were basically occupied by steel structure materials, but FRP broke this situation and successfully squeezed the market, all of which are the benefits of quality. Compared with ordinary carbon steel, the comprehensive finished product of FRP grating is low. Although its one-time investment is higher than that of ordinary carbon steel, due to its long service life, it can generally be used for 20 years without maintenance. The comprehensive economic benefits are much better than the use of carbon steel. Compared with traditional metal materials and non-metallic materials, FRP grids have the characteristics of high strength, good performance, energy saving, large product design freedom, and wide product application adaptability.
