1. High strength, the tensile strength of FRP Angle steel is 150 ~ 300MPa, the bending strength is 200 ~ 300MPa, after 1000h artificial accelerated aging, the retention rate of bending strength can reach 78%
2. The deformation rate is low. After 1000h artificial accelerated aging, the length change of FRP Angle steel is +0.03% and the width change rate is -0.07%. Therefore, the geometric shape and size of products made from the pultrusion profile can be maintained stable for a long time.
3. The thermal deformation temperature is high. The thermal deformation temperature of FRP Angle steel is 186ºC.
4. Low water absorption rate, ordinary FRP products water absorption rate is less than 0.5%, and the water absorption rate of FRP Angle steel is only 0.257%, suitable for use in a humid environment.
5. Strong corrosion resistance, the hardness retention rate of FRP Angle steel soaked in 3%HCI aqueous solution for 24h is 95%; After immersion in 3%NaCl solution for 24h, the hardness retention rate was 89%.
6.To meet the environmental requirements, the production process used for processing FRP Angle steel has the characteristics of low noise, high efficiency, low power consumption, low pollution, etc., which conforms to the relevant national environmental requirements
