FRP pultruded profile

Extruded glass fiber reinforced plastic profile is made of continuous glass fiber covered with glass fiber felt, immersed in unsaturated polyester resin (or epoxy resin, phenolic resin), heated and pultruded. The profile is very tough and firm, and the absolute value of its longitudinal bending strength and impact strength has exceeded that of ordinary steel. Anti-corrosion performance, high temperature resistance performance, good insulation performance. Products have a long service life in places with acid and alkali media. The scope of use in all aspects of industry and civil use continues to expand, and it is becoming more and more popular.

Our company produces a variety of FRP profiles to meet the needs of various industries. Our FRP pultruded profiles include: various FRP fences, FRP insulated leisure benches, FRP flat bars, special-shaped tubes, transparent rods, steel pipes, hexagonal shaft bars, FRP square tubes, round tubes, I-beams, purlins, angle steels , Deck, round bar, strip steel, channel steel, pultrusion bracket, glass fiber reinforced plastic inclined ladder, ladder cage, glass fiber reinforced plastic platform, sign pile, etc.

(1) High strength

The tensile strength of the pultruded profile is 150-300MPa, the bending strength is 200-300MPa, and the bending strength retention rate after 1000h artificial accelerated aging can reach 78%.

(2) Low deformation rate

The length change of FRP pultruded profile after 1000h artificial accelerated aging is +0.03%, and the width change rate is -0.07%. Therefore, the geometric shape and size of products made with the pultruded profile can be kept stable for a long time.

(3) High heat distortion temperature

The heat deformation temperature of the pultruded profile is 186℃, it will not soften at high temperature, and will not be brittle at -60℃, which ensures the normal use under various ambient temperatures.

(4) Low water absorption

The water absorption of ordinary FRP products is less than 0.5%, while the water absorption of pultruded profiles is only 0.257%, which is suitable for use in humid environments.

(5) Low thermal insulation coefficient

The heat transfer coefficient of the pultruded profile is close to that of rigid PVC. The heat insulation coefficient of the single-frame double-glass insulation window made of it is only 2.69W/(m2?K), while the same type made of steel and aluminum The thermal insulation coefficient of the window is as high as 4.0W/(m2?K), indicating that the energy saving of FRP doors and windows is very obvious.

(6) Strong corrosion resistance

The pultruded profile is soaked in 3% HCI aqueous solution for 24 hours, and its hardness retention rate is 95%; after soaked in 3% NaCl solution for 24 hours, its hardness retention rate is 89%. Therefore, doors and windows made of glass fiber reinforced plastic pultruded profiles are not only suitable for ordinary houses, hotels, restaurants, but also for industrial plants in coastal areas and corrosive working environments.

(7) Adapt to environmental requirements

The production process used for processing pultruded profiles has the characteristics of low noise, high efficiency, low power consumption, and low pollution, which meets the relevant national environmental requirements.
