Why choose FRP? Compared with FRP, stainless steel has a complex manufacturing process.Otherwise it will cause the defect of surface treatment,. Moreover,it is more heavier than frp. Compared with FRP, carbon steel has lower strength and its strength is inversely proportional to plasticity.At the same time , it is easy to rust. Compared with FRP, PVC has low strength, poor design, poor heat resistance and complex installation.It is easy to age and has low strength retention after a long time.What’s more,the application is smaller than frp, the maintenance is not convenient. frp pultruded grating provides the following advantages: High weight-to-strength ratio Bi-directional load Aesthetics outlooking Good application for waterfront No maintenance needed after installation Slight elasticity Electric,heat and sound insulation Good resistance to weathering No rust Long service time Application: frp pultruded grating is widely used in chemical, electroplating, paper making, wine making, pharmacy, metallurgy, food processing, transportation, textile printing and dyeing, wastewater treatment, ocean exploration and many other industries as well as nuclear power plants, power plants.
