Glass fiber reinforced pultruded profiles are a composite material formed by using unidirectional glass fiber roving as the reinforcing matrix and thermosetting resin as the matrix material. Continuous glass fiber roving imparts the product with high longitudinal strength, while glass fiber mat enhances its transverse strength.
Common thermosetting resin matrices typically include unsaturated polyester resin, vinyl ester resin, epoxy resin, and phenolic resin. These matrices provide products with excellent corrosion and weather resistance. Different resins allow the products to be suitable for various harsh corrosive environments. For specific details, please inquire.
Fiberglass pultruded profiles include round tubes, round bars, angle iron, I-beams, channel steel, square tubes, rectangular tubes, heart-shaped tubes, flat strips, cable trays, doors and windows, sports equipment, and other standard profiles, as well as custom-shaped profiles to customer specifications. Fiberglass profiles are widely used in chemical corrosion prevention, wastewater treatment, electrical insulation, energy exploration, transportation, and electronic communication fields due to their outstanding lightweight, high-strength, corrosion-resistant, and insulating properties.
Key characteristics of fiberglass pultruded profiles: smooth surface, attractive appearance, acid resistance, lightweight yet high strength, insulating, flame retardant, anti-aging, non-magnetic, uniform dimensions. Their longitudinal bending and impact strengths exceed those of ordinary steel, and their service life is typically over 50 years.
This product is widely used in: energy, chemical industry, transportation, construction, printing machinery, textile machinery drive shafts, electrical insulating ladders, household ladders, tool handles, cable protection covers, antenna covers, oil transportation pipelines, sewage treatment pipelines, purified water treatment pipelines, and other fields.
Glass fiber reinforced plastic (GFRP) extruded profiles boast excellent surface characteristics: they rarely produce corrosion when in contact with chemical media and are also unlikely to scale, making them ideal for manufacturing fluid pipelines. These pipelines offer minimal internal resistance and a low friction coefficient, thus saving considerable energy. Additionally, since composite materials typically do not generate metal ions as easily as metals, this is why they are widely used in the food and pharmaceutical industries. Moreover, composites have a high friction (PV) limit, and under water-lubricated conditions, their friction coefficient is very low, approximately 0.01 to 0.03, making them a prime material for wear-resistant products.
Characteristics of glass fiber reinforced plastic pultruded profiles:
1. Corrosion-resistant: Capable of withstanding corrosion from acidic, alkaline, organic solvents, and salt-based media, offering unparalleled superiority compared to other metals.
2. Lightweight and High-Strength: The interlaced weaving and full resin impregnation of the integral molding structure offer a strength 10 times that of rigid PVC. The absolute strength far exceeds that of aluminum, reaching the level of common steel.
3. Flame retardant, impact-resistant, and aging-resistant.
4. Safety: Insulated, non-magnetic, anti-slip, no electrical sparks, fatigue-resistant
5. Easy Installation: Due to the lightweight nature of fiberglass, the weight of the components is significantly reduced, thereby decreasing the weight of the supporting structure. Installation does not require lifting equipment, saving both time and effort.
