Its production adopts the extrusion molding process. Fiberglass yarn bundles are impregnated with resin and pulled into molds for molding, then heated and cured to form profiles with stable cross-sections, such as square tubes, round tubes, I-beams, angle steels, etc. These profiles come in various specifications, with common sizes including 20x20 mm, 30x30 mm, 50x50 mm, and 100x100 mm. The thickness, color, and strength can be customized according to specific needs. General parameters: Density: 1.8-2.0 g/cm ³ Tensile strength: ≥ 400 MPa Bending strength: ≥ 350 MPa Insulation: Dielectric strength ≥ 10 kV/mm, suitable for power insulation.
Fiberglass extruded profiles are widely used in industries such as construction, chemical, marine engineering, and power due to their excellent performance. They are commonly used in platform structures, guardrails, cooling tower brackets, and power insulation equipment, providing lightweight and durable structural material solutions for multiple industries.

Pultrusion process will continue the continuous fiber, belt, cloth, or felt of the impregnated resin glue, and continuously produce a forming process of the glass reinforcement profile with unlimited length under the effect of squeezing mold molding, solidifying, and continuously producing. It is suitable for the production of glass reinforced profiles that produce various sections, such as pipes, sticks, physical profiles (types, grooves, squares), and empty stomach profiles (doors and windows profiles, leaves).
