FRP Heavy Duty Grating
Product performance introduction
FRP Heavy Duty Grating, or Fiberglass Reinforced Plastic Heavy Duty Grating, is a robust, corrosion-resistant structural flooring material designed to withstand high loads in harsh industrial environments. Manufactured by combining fiberglass rovings with thermosetting resins such as isophthalic, vinyl ester, or phenolic resins, this type of grating provides an outstanding balance of strength, chemical resistance, and long-term durability. Compared to traditional materials like steel, FRP grating offers significant advantages such as low maintenance requirements, high strength-to-weight ratio, and excellent resistance to corrosion, rust, and impact.
Heavy-duty FRP gratings are specifically engineered to handle vehicular traffic, including forklifts, trucks, and other heavy machinery. They come in various panel sizes, bar thicknesses, and mesh configurations to meet different load and span requirements. Pultruded and molded varieties are both available, with pultruded grating offering higher load capacity and molded grating excelling in corrosion resistance. These gratings are ideal for applications such as trench covers, loading docks, platforms, ramps, and flooring in wastewater treatment plants, offshore platforms, and chemical processing facilities.
Safety is another key feature of FRP heavy-duty grating. The surface can be customized with anti-slip grit or concave finishes to reduce the risk of slips and falls, even in wet or oily environments. Additionally, its non-conductive and non-magnetic properties make it suitable for electrical applications. FRP gratings are also UV-resistant and fire-retardant depending on resin selection, extending their life cycle in outdoor or extreme conditions.
