2. Material Characteristics

• Fiberglass Reinforced Plastic (FRP)

  : Composed of glass fibers and resin composite, it possesses:

•  High strength and impact resistance (5-8 times stronger than ordinary plastics)

•  Resistance to acid and alkali corrosion (service life of 10-15 years)

• Lightweight (only 1/4 the weight of steel)

• Insulation and flame retardancy (oxygen index ≥28)
