Glass-reinforced plastic (GRP) grating is manufactured by interlacing glass fibers and then casting a resin to form a solid molded product. The GRP grating panels, featuring many regularly distributed rectangular and square openings, possess bidirectional isotropic mechanical properties. They are widely used in work platforms, equipment platforms, drilling platforms, walkways, and more in industries such as petrochemicals, electronics, electricity, paper, dyeing, electroplating, marine exploration, and wastewater treatment. Ideal for corrosive environments, these grating panels are also suitable for civil building facilities.
