To understand the use of FRP pultruded profiles, we first understand the common products of FRP pultruded profiles, such as square tubes, round tubes and rods, rectangular tubes, day tubes, purlins, angle steels, channel steels, I-beams and so on. Due to the designability of FRP, as long as the mold is designed in advance, it can be pultruded into the desired product and different specifications. FRP pultruded profiles are often used in chemical processing plants, marine construction, food and beverage processing, petroleum smelting, paper industry, sewage treatment and transportation industries.
Advantages of FRP pultruded profiles:
1. FRP pultruded profiles are resistant to high temperatures. FRP materials have good high temperature resistance. The use of FRP pultruded profiles can withstand high temperatures of 330 degrees Celsius.
2. FRP pultruded profile products have good corrosion resistance. It can withstand the corrosion of various gas and liquid media such as acids, alkalis, and salts to different degrees, and will not rust.
3. The glass fiber content of pultruded profiles is higher than other composite material forming technologies, so the longitudinal strength is very high, which is equivalent to steel. The density of pultruded profiles is only about one-fourth of that of steel, so the specific strength is much higher than that of steel.
