The company will select the corresponding glass fiber reinforced plastic grid to maximize the economic benefits based on the user's performance requirements for the FRP grating. According to the corrosive medium in the use environment, the user can inquire the guideline of the company's corrosion resistance and determine the most economical resin type. According to the load method, load, net span and support structure, refer to the company's mechanical load carrying capacity. Table to determine the most economic type of grille specification.
