FRP pultruded profiles are structural shapes made from fiber reinforced plastic using a continuous manufacturing process called pultrusion. This process involves pulling fibers—typically glass, carbon, or aramid—through a resin bath and then through a heated die to cure and shape the composite material into constant cross-sectional profiles. The result is a strong, lightweight, and corrosion-resistant product suitable for a wide range of industrial, commercial, and structural applications.

Six functional characteristics of FRP pultruded profiles
Corrosion resistance
FRP pultruded profiles have excellent corrosion resistance, can withstand the corrosion of various gas and liquid media such as acids, alkalis, organic solvents, and salts in different degrees, and will never rust. , there is o-phthalic, isophthalic, vinyl, etc. for selection, please refer to the table of corrosion resistance of pultruded profiles.
Lightweight and high strength
The glass fiber content of pultruded profiles is higher than other composite material forming technologies, so the longitudinal strength is very high, which is equivalent to that of steel. The density of pultruded profiles is only about a quarter of that of steel, so the specific strength is much higher than that of steel. The modulus of pultruded profiles It is lower than steel, generally only 1/7 to 1/10 of steel.
Anti-aging
FRP pultrusion profiles are made of high-quality thermosetting resin and glass fiber system, which is different from ordinary thermoplastics. The normal service life of the product can reach 20 years. The best anti-aging effect can be obtained by adding an anti-ultraviolet agent and selecting polyester fiber felt.
Easy maintenance
FRP pultruded profiles are produced by distributing pigments into resins. The color of the product can be freely distributed according to customer needs. It is not easy to fade, does not need paint protection, and has a self-cleaning effect.
Excellent electromagnetic performance
FRP pultruded profiles have excellent electrical insulation, no electromagnetic and electric sparks, and can be used in equipment areas with conductive hazards and active magnetism, as well as inflammable and explosive places.
Thermal function
FRP pultruded profile is a kind of thermal insulation material, the thermal expansion coefficient is much lower than that of ordinary plastics, pultruded profile has excellent mechanical properties at low temperatures, and will not melt at high temperatures, but the strength and modulus will vary at high temperature The applicable temperature range of general pultruded profiles is -50°C to 100°C.
1,350 mm width
600 mm height
And a thickness of 2.5 - 40 mm.
Customized production is possible in accordance with customers' requirements.
FRP Pultrusion Process Steps
The basic steps of FRP pultrusion process are:
Feeding
The fiber reinforcements, such as rovings or mats, are fed from a creel into a guide that aligns them in the desired direction.
01
Impregnation
The fibers are pulled through a resin bath or a resin impregnator that saturates them with the resin matrix and any additives.
02
Forming
The wetted fibers are pulled through a heated metal die that shapes them into the desired cross-section and initiates the resin curing.
03
Pulling
The cured FRP product is pulled by a traction device that provides the driving force for the process. Cutting: The FRP product is cut by a saw or a cutter into the required length.
04
Application of FRP Pultrusion Process
FRP pultrusion process has many applications in various industries, such as:
Construction: FRP pultruded products can be used as structural components for buildings, bridges, decks, railings, gratings, roofing, and flooring. They offer advantages such as light weight, high strength, corrosion resistance, fire resistance, and design flexibility.
Electrical: FRP pultruded products can be used as electrical insulators for transformers, switchgears, cables, poles, and towers. They offer advantages such as electrical insulation, thermal stability, moisture resistance, and low maintenance.
Automotive: FRP pultruded products can be used as parts for vehicles, such as bumpers, spoilers, chassis, body panels, and engine components. They offer advantages such as weight reduction, fuel efficiency, impact resistance, and aesthetic appeal.
Marine: FRP pultruded products can be used as components for boats, ships, submarines, offshore platforms, and pipelines. They offer advantages such as seawater resistance, buoyancy, fatigue resistance, and durability.
