FRP Pultruded Section
Product performance introduction
FRP Pultruded Sections are structural profiles made from Fiber Reinforced Polymer (FRP) using a manufacturing process called pultrusion. This method involves pulling continuous strands of reinforcing fibers (typically glass or carbon) through a resin bath and then through a heated die to form profiles of constant cross-section. The result is a lightweight, high-strength, corrosion-resistant material ideal for a wide range of structural applications.
Common FRP pultruded shapes include I-beams, channels, angles, square tubes, round tubes, flat bars, and custom profiles. These sections are widely used in industries such as construction, chemical processing, electrical, marine, and infrastructure, where traditional materials like steel, aluminum, or wood are prone to corrosion, rot, or electrical conductivity issues.
The key benefits of FRP pultruded sections include:
- Corrosion resistance: Ideal for harsh chemical environments, offshore platforms, or wastewater treatment plants.
- High strength-to-weight ratio: Stronger than steel by weight, yet up to 75% lighter, making transportation and installation easier.
- Electrical insulation: Non-conductive, suitable for high-voltage environments and power plants.
- Durability: Unaffected by UV exposure, saltwater, and most chemicals; minimal maintenance required.
- Design flexibility: Available in a wide range of shapes, sizes, and custom designs.
These profiles comply with international standards such as ASTM D638, ASTM D790, EN 13706, and can be engineered to meet specific load-bearing requirements. They are also fire-retardant and UV-stabilized when needed.
