Fiberglass Reinforced Plastic (FRP) gratings, also known as FRP grating panels, are a type of plate material composed of glass fiber as the reinforcing material and unsaturated polyester resin as the matrix, which is specially processed and compounded to form many apertures. FRP gratings can be used as structural materials for floors, trench covers, platforms, ship decks, stairs, walkways, and more in corrosive environments. They feature corrosion and flame resistance, non-magnetic insulation, vibrant colors, and a variety of styles and forms available.
