Specifications

1. Properties of GRP pultruded profiles 

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. 

C. Anti-corrosion 
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. 

E. Non-conductive 
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. 

G. Aesthetics 
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. 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. 

3. GRP pultruded profiles can meet the customer's requirements by using different combination of resin, fibers and others. 

4. GRP pultruded profiles offer a unique combination of chemical resistance, size stability, high strength, and thermal/electric non-conductivity, etc. 

5. GRP pultruded profiles are widely used and according to their diameter they may be used as umbrella frames, underground cable jackets, cable cores (bearing tensile stress), handles of spade and hammer, structural members, handrails, water pipes, and mobile telecom outdoor antennal covers.
