Composite (GFRP) Poles

What is GFRP (Glass Fiber Reinforced Plastic)?

GFRP is a composite material made of a polymer matrix reinforced with fiber, aiming to form better physical and chemical properties. GFRP is a production material such as metal, wood, glass, concrete. GFRP materials has important advantages as against other production materials, new features can be acquired according to requirements.


What is GFRP Pole?

GFRP poles whose raw materials are fiber glass, resin, chemical additives and pigmeni are produced by ventrifuge and RTM (Resin Transfer Molding) methods. Centrifuge method is used for 3 and 4 mt poles, RTM is usef for 8 mt poles. Between 4 and 8 mt poles, as 4.25, 5, 6 and 7 mt, steel reinforcement is used. GFRP poles are tested during and after manufacturing process to control their physical and mechanical features that they are proper to standarts or not. GFRP poles are light, anti-corrosive, have high chemical and mechanical features and non-conductive because of their ram materials.

GFRP poles are cylindrical tapered shape and one-piece.

Components: Resin, glass fiber, additives and pigment are the basic components of the GFRP materials. It can be produced any material which are proper for the requirements by changing these components.


Resin: Chemical resistance, flexibility and UV resistance of the GFRP gratings are determined by the resin. Resins are chose according to the environment; orthophthalic resin for general usage, isophthalic resin for chemical environment and vinyl ester resin for extremely heavy chemical environment.


Glass Fiber: Multi-layered continuous glass fibers are used in production. Molded GFRP gratings have high mechanical resistance due to glass fiber.


Additives: Additives such as UV stabilizers, flame retardants and low smoke density retardants increase mechanical and chemical resistance and add new superior features.


Pigment: Pigments make it possible to give the GFRP gratings any color. This makes it happen to use GFRP gratings in architectural projects.
