FRP Channel features: 1. High strength: Tensile strength of channel is 150 ~ 300MPa, flexural strength is 200 ~ 300MPa. 2. Low water absorption: ordinary fiberglass channel of water absorption is less than 0.5%, while the pultrusion channel water absorption is only 0.257%, suitable for use in wet environments. 3.The corrosion resistance: channel material is made of resin and glass fibers, which can effectively resist the erosion of domestic sewage, corrosive soil, chemical waste acid, alkali, salt and other corrosive media and untreated, and many chemical liquids . 4. Other excellent performance: impact-resistant, maintenance-free, easy processing, non-slip safety, insulation thermal insulation. FRP Channel usages: Widely used in chemical plants, marine construction, food and beverage processing, oil refining, paper industry, sewage treatment and transportation and other areas
