1. Properties of FRP pultruded profiles
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.
C. Anti-corrosion
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.
E. Non-conductive
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.
G. Aesthetics
FRP 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. The pultruded FRP pipes 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. The pultruded FRP pipes can meet the customer's requirements by
using different combination of resin, fibers and others.
4. The pultruded FRP pipes offer a unique combination of chemical
resistance, size stability, high strength, and thermal/electric
non-conductivity, etc.
5. The pultruded FRP pipes 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.
