Runfeng has carried out a number of tests on the special rational energy parameters of FRP light plate, and the common data are as follows:
Bending strength: 110MPa;Tensile strength: 84MPa;
Impact strength: 98MPa;Thermal expansion coefficient: 2.2x10-5cm /CM/℃.
In coastal areas with strong typhoon, typhoon lifting roof slab often happens. It is recommended to increase the density of roof eaves and ridge purlins (≤750mm).This is also applicable to the color painted board roof, the design should consider the roof water climbing phenomenon under the action of wind pressure. http://www.frpexpert.com
