Pultruded fiberglass grating is a type of fiberglass-reinforced plastic (FRP) grating, manufactured through the pultrusion process. This process involves pulling continuous fiberglass strands through a resin bath and then through a heated die to create a strong, uniform product. It is widely used in applications such as walkways, platforms, and stair treads in industrial environments.
