A. High strength
FRP 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
FRP 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.
FRP 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
FRP are transparent to radio waves, microwaves and other electromagnetic. It is widely used to make antennas.
FRP has low thermal/ electrical conductivity.
F. Dimensional stability
The coefficient of thermal expansion of FRP is slightly less than steel and significantly less than aluminum.
2.Craft and Raw Materials
FRP Pultruded flat bars 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. Some normal sizes of FRP Flat bar are as follows
(Pls note special sizes are also welcomed.)
FRP pultruded flat bars can meet the customer's requirements by using different combination of resin, fibers and others.
FRP pultruded flat bars offer a unique combination of chemical resistance, size stability, high strength, and thermal/electric non-conductivity, etc.
FRP pultruded flat bars are widely used for chemical processing, oil and gas, electrical and utility, wastewater treatment, transportation, construction etc.
5. There are some FRP Flat bars that our factory produced in recent years.
6. Following is General Physical Parameters of FRP Pultruded Profiles.(If have special requirements, pls contact Nanjing Jinglue.)
