A. High strength
GRP is stronger than structural steel on a pound-for pound basis. It has been used to buildings, walkway, sub-floors and platforms.
B. Light weight
GRP is 20-25% the weight of steel and 70% the weight of aluminum. FRP are easily transported, handled and lifted into place. Total structures can often be preassembled and shipped to the job site ready to installation.
GRP will not rot and are impervious to a broad range of corrosive elements. This feature makes FRP a natural selection for indoor or outdoor structures in pulp and paper mills, chemical plants, water and sewage treatment plants, structural near salt water and other corrosive environments.
D. Electro-magnetic transparency
GRP are transparent to radio waves, microwaves and other electromagnetic. It is widely used to make antennas.
GRP has low thermal/ electrical conductivity.
F. Dimensional stability
The coefficient of thermal expansion of GRP is slightly less than steel and significantly less than aluminum.
GRP are pigmented throughout the thickness of the part and can be made to virtually any desired custom color. Special surfacing veils are also available to create special surface appearances such as wood grain, marble, granite, etc.
2. Craft and Raw Materials
GRP pultruded profiles are manufactured with the pultrusion process after choosing the correct raw materials major including the resin, fibers and additives according to the profiles requirement including mechanical strength, electrical insulation, anti-corrosion etc.
GRP pultruded profiles can meet the customer's requirements by using different combination of resin, fibers and others.
GRP pultruded profiles offer a unique combination of chemical resistance, size stability, high strength, and thermal/electric non-conductivity, etc.
The above FRP profiles are widely used in electricity as its good combination of low electrical conductivity and high anti-corrosion.
