Molded FRP gratings use high strength fiberglass roving as reinforcing material, together with unsaturated polyester resin. These products have the best bi-direction mechanical properties, with good chemical resistance can be achieved by using superior polyester resin. Molded FRP gratings are widely used in the power generation, sewage treatment, oil refining and oceanographic survey fields as work floors, stair treads, and trench covers for loading frames. Apart from standard panels, we can also produce gratings of different thickness, mesh and panel size. Surfaces available include concave top, smooth grating, gritted top, covered with grit, flat or decorative plating.
