To understand the differences between molded and pultruded grating, it is important to know exactly what Fiberglass Reinforced Plastic (FRP) is. FRP is an alternative to traditional industrial materials, such as steel, concrete, and wood. It is made by combining resin with fiberglass. Resin formulations, resin proportions, and manufacturing techniques allow this product to be used as gratings, handrails, ladders, platforms, and custom engineered solutions. Often people ask, “What is the difference between molded and pultruded grating?” Fibergrate wants to help people make the right decision when it comes to choosing the right material for their next project. Some people might simply say: “Molded grating is a panel that has a square or rectangular top mesh whereas pultruded grating is composed by a series of parallel bars.” Is it really this simple? Please allow us to explain.
