Thermal expansion coefficient ρ(CM/CM/℃) : ρ FRP = 2.2x10-5;ρ iron = 1.5x10-5;(thermoplastic PC light plate is ρ PC = 6.8x10-5).The thermal expansion coefficient of FRP and steel is basically the same, so that the displacement caused by temperature difference is basically the same, and the leakage caused by nail hole ****ing and plate deformation is reduced. http://www.frpexpert.com
