FRP Pole Manufacturing Process

FRP poles are made through a pultrusion process that involves fiber rolls and resin. This creates a strong and durable pole that boasts impressive physical, chemical, and mechanical properties

Raw Materials

Fiber Roving

A roving is a long and narrow bundle of fiber. Their main use is as fiber prepared for spinning, They provide the strength, rigidity and electrical insulation properties.

Unsaturated Polyester Resin

unsaturated polyester, any of a group of thermosetting resins produced by dissolving a low-molecular-weight unsaturated polyester in a vinyl monomer and then copolymerizing the two to form a hard, durable plastic material.

Fiber Sheet Rolling

A fiber roll is a temporary erosion control and sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment erosion. It is made of straw, coconut fiber or similar material formed into a tubular roll.

The Pultrusion Process

Heated Die

During pultrusion, the resin and fibers are pulled through a heated die. This shapes the pole and activates the resin to harden.

Pulling Device

A pulling device pulls the fibers through the die at a constant speed. This helps create a uniform pole with the desired properties.

Cut Off Process

A cut off process is used to trim the pole to the correct length. This completes the pultrusion process.

Physical Properties of FRP Poles

1 Lightweight

FRP poles are 80% lighter than steel poles.

2 Corrosion Resistance

They are resistant to corrosion and do not rust. This makes them ideal for outdoor use.

3 UV Resistant

FRP poles can withstand UV radiation without degradation.

4 Impressive Strength

Despite being lightweight, they have incredible strength and rigidity, making them ideal for high load applications.

Mechanical Properties of FRP Poles

1

Flexibility

FRP poles have a high tolerance for bending and flexing.

2

Thermal Stability

They are thermally stable and can withstand extreme temperature changes without deformation.

3

Vibration Resistance

FRP poles are highly resistant to vibrations, which makes them ideal in earthquake-prone areas.

Advantages of FRP Poles

Environmentally Friendly

They are eco-friendly and can be easily recycled at the end of their lifespan.

Cost-Effective

FRP poles are cost-effective and require less maintenance compared to traditional poles. Light Weight and Easy to Installed.

Durable

FRP poles are long-lasting and have a lifespan of over 50 years.

Applications of FRP Poles

Utility Poles

FRP poles are widely used as utility poles because of their superior strength, high dielectric strength, and lightweight nature.

Street Lighting

FRP poles are also used as street light poles for their vibration resistance and high strength.
