Pultruded Rods, Tubes & Custom Profiles

Glasforms™ Pultruded Rods, Tubes & Custom Profiles

Stiffness, Strength, & Weight Reduction

Glasforms' pultrusion process creates continuous, constant cross-section profiles with consistent, uniform quality and exceptional mechanical performance. These continuous fiber-reinforced polymer composites are ideal in applications where high stiffness and light weight performance are critical.

Standard and custom shapes and sizes are available with a variety of resins including polyester, vinyl ester, and epoxy, and reinforcements including mat/roving (MR-GFRP) or unidirectional (U-GFRP) fiberglass, or high performance unidirectional carbon fiber.

Our design and engineering experts can help select the materials to meet your specific stiffness, weight, strength, flex, density, and tensile requirements.
