Profiles are produced by continuous pultrusion process, which allows elaborating profiles of plastics reinforced with continuous threads of fiberglass. These mats absorb charges and longitudinal forces, able to support high tensions. GRP profiles have a polyester matrix reinforced with fiberglass fabrics up to 65%; therefore, they offer a great versatility in construction of platforms, walkways and stairs. The application of the profiles gets a great importance in works with big dimensions where quality, weight and resistance are the key. The GRP profile gratings are based according to the beams in the load direction joint by bars and distant tubes, fixed with specific adhesives and with no torsion problems.
