FRP Pultruded Profile
FRP Pultruded Profile
FRP pultruded profiles, also called fiberglass structural shapes, are composite components manufactured by pulling fiber reinforcements through a resin bath and a heated die. The process produces continuous profiles with a constant cross-section, combining glass or other fibers with thermosetting resins.
Common reinforcements include glass fiber rovings, mats and fabrics. Resin systems include polyester, vinyl ester, epoxy and phenolic. Auxiliary materials such as release agents, curing agents, UV stabilizers and pigments are selected according to application requirements.
These profiles are produced on pultrusion machines using pultrusion dies. For reinforcement applications, see our FRP rebar.
Material Advantages
High Strength-to-Weight Ratio: Lighter than steel and aluminum for many structural applications while providing adequate strength
Corrosion Resistance: Resists rust and degradation in many chemical, marine and outdoor environments
Low Maintenance: No painting or protective coating required in many applications
Dimensional Stability: Resists warping and maintains shape under typical service loads
Electrical Insulation: Non-conductive properties make it suitable for electrical and utility applications
Design Flexibility: Can be manufactured in a wide range of shapes, sizes and resin formulations

FAQ
What are FRP pultruded profiles?
FRP pultruded profiles are composite structural shapes made by pulling fiber reinforcements through resin and a heated die. They include angles, channels, I-beams, tubes, rods and flat bars.
What are the advantages of FRP pultruded profiles?
FRP pultruded profiles are lightweight, corrosion resistant, non-conductive and low maintenance. They can provide a good strength-to-weight ratio for structural and industrial applications.
What shapes are available?
Standard shapes include angles, channels, I-beams, square tubes, rectangular tubes, round tubes, rods and flat bars. Custom profiles can be manufactured for specific engineering requirements.
Are FRP pultruded profiles corrosion resistant?
Yes. FRP pultruded profiles resist moisture, chemicals and salt exposure in many applications, making them suitable for harsh environments where metal may corrode.
Can FRP pultruded profiles be customized?
Yes. Dimensions, resin systems, colors, fiber content and surface finishes can be customized to meet project-specific mechanical, chemical and aesthetic requirements.
What industries use FRP pultruded profiles?
FRP pultruded profiles are used in chemical processing, water treatment, electrical utilities, construction, marine, offshore, transportation and general industrial applications.
Do FRP pultruded profiles provide electrical insulation?
Yes. FRP pultruded profiles are non-conductive, making them suitable for electrical supports, cable trays, substations and other installations where insulation is important.
