Fiberglass 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. The continuous glass fiber roving imparts the product with exceptional longitudinal strength, while the glass fiber mat provides good transverse strength.
Common thermosetting resin matrices typically include unsaturated polyester resins, vinyl ester resins, epoxy resins, and phenolic resins. These matrices provide excellent corrosion and weather resistance to the products. Different resins enable the products to be suitable for various harsh corrosive environments. For specifics, 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, windows and doors, sports equipment, and other standard profiles, as well as customized non-standard profiles to customer specifications. Fiberglass profiles are widely used in fields such as chemical corrosion protection, wastewater treatment, electrical insulation, energy exploration, transportation, and electronic communication due to their outstanding lightweight high-strength, corrosion-resistant, and insulating properties.
Key features of glass fiber reinforced pultruded profiles: smooth surface, attractive appearance, acid and alkali resistance, lightweight yet high strength, insulating, flame-retardant, anti-aging, non-magnetic, uniform dimensions. Their longitudinal bending strength and impact strength exceed that of ordinary steel, with a service life typically extending over 50 years.
This product is widely used in fields such as energy, chemicals, transportation, construction, printing machinery, textile machinery drive shafts, electrical insulation ladders, residential ladders, tool handles, cable protectors, antenna covers, oil pipeline, sewage treatment pipeline, and purified water treatment pipeline.
Glass fiber reinforced plastic extruded profiles offer excellent surface properties: Generally, they produce very little corrosion when in contact with chemical media and are also seldom scaling. Therefore, they are commonly used to manufacture fluid pipelines, which have low internal resistance and a low friction coefficient, resulting in significant energy savings. Since composite materials usually do not generate metal ions that can contaminate media as easily as metals do, this is also the reason for their widespread application in the food and pharmaceutical industries. Additionally, composites have a high friction (pv) limit, and under water-lubricated conditions, their friction coefficient is very small, approximately 0.01 to 0.03, making them an ideal material for wear-resistant products.
Characteristics of glass fiber reinforced plastic pultruded profiles:
1. Corrosion-resistant: Resists corrosion from acidic, alkaline, organic solvents, and salts, among other liquid and gaseous mediums, offering unparalleled superiority compared to other metals.
2. Lightweight and High-Strength: The interlaced weaving and thorough resin impregnation result in an overall structural strength 10 times that of rigid PVC. The absolute strength far exceeds aluminum, reaching the level of ordinary 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 components is significantly reduced, thereby minimizing the weight of the supporting structure. Installation does not require lifting equipment, saving both time and effort.
