FRP Pultrusion Profiles: square tube, round tube, rectangular tube, purlin, pipe, I beam, H beam, angle beam, L beam, channel, U channel, C channel, rod, bar, rebar, post, etc.Â
The reason for choosing FRP pultruded profiles is its unique performance advantages, especially in terms of corrosion resistance, light weight and high strength, insulation and design flexibility. The following is a comparison of FRP pultruded profiles with metals and plastics:
1. Corrosion resistance
FRP: It has strong resistance to corrosive media such as acids, alkalis, and salts, and is suitable for corrosive environments such as chemical and marine.
Metal: It is susceptible to corrosion and requires additional protection (such as plating, coating), which increases costs.
Plastic: It has good corrosion resistance, but poor mechanical strength and temperature resistance.
2. Lightweight and high strength
FRP: Low density, high strength, better specific strength than many metals, easy to transport and install.
Metal: High density and heavy weight, which increases the difficulty of transportation and installation.
Plastic: Lightweight, but low strength, difficult to withstand high loads.
3. Insulation
FRP: Excellent electrical insulation, suitable for electrical equipment and high voltage environments.
Metal: Strong conductivity, not suitable for insulating occasions.
Plastic: Good insulation, but poor mechanical strength and heat resistance.
4. Design flexibility
GRP: Can be designed into various complex shapes through molds to meet diverse needs.
Metal: Processing complex shapes is costly and difficult.
Plastic: Easy to shape, but insufficient strength and heat resistance.
5. Fatigue resistance
GRP: Good fatigue resistance, suitable for dynamic loads.
Metal: Easy to fatigue, cracks may appear after long-term use.
Plastic: Poor fatigue resistance, easy to deform under long-term stress.
6. Low maintenance cost
GRP: Almost maintenance-free and long life.
Metal: Regular maintenance is required to prevent corrosion.
Plastic: Low maintenance cost, but easy to age.
7. Environmental protection
GRP: Recyclable, low production energy consumption.
Metal: Recyclable, but high production energy consumption.
Plastic: Partially recyclable, but difficult to degrade, easy to pollute the environment.
Fiberglass pultruded profiles are superior to metals and plastics in terms of corrosion resistance, light weight and high strength, insulation, and design flexibility. They are suitable for a variety of harsh environments, have low maintenance costs, and are environmentally friendly.
