Their combination of strength, dimensional stability, and long service life makes them suitable for a wide variety of industrial applications.

What Are GRP Pultruded Profiles?

Glass Reinforced Plastic (GRP), also known as Fiberglass Reinforced Plastic (FRP) in many regions, is a composite material manufactured by combining glass fibers with polymer resins. Pultrusion is a continuous manufacturing process in which glass fiber reinforcements are pulled through a resin bath and heated die to produce profiles with a consistent cross-section.

Unlike conventional fabrication methods, pultrusion creates highly uniform structural components with predictable mechanical properties. The resulting profiles are available in numerous shapes, including:

I-beams

Channels

Angles

Square tubes

Round tubes

Flat bars

Hollow sections

Custom structural profiles

These products are engineered to deliver excellent structural performance while remaining significantly lighter than steel.
