Glasforms™ Pultrusion Technologies

Custom cross-sectional rods and profiles for any length with consistent and uniform quality throughout

Glasforms pultrusion technologies provide customers with the most economic method of producing continuous fiber-reinforced polymer composites. Fiber reinforced composites are ideal in applications where high stiffness and light weight performance are critical. Through our automated process, we can produce continuous and linear cross section profiles based on an engineered resin matrix.

Glasforms pultruded products offer consistent quality and exceptional product performance. In addition to custom shapes and sizes, customers can work with our engineers to design a custom polymer matrix to create the right balance of price and performance.    


Our pultrusion process offers:

  • Exceptionally high mechanical properties for lightweight structures
  • Linear, constant cross-section profiles
  • Continuous, automated manufacturing process
  • Custom shapes and sizes
  • Consistent and uniform quality and material properties

Customers can also request a variety of custom shapes and sizes of pultruded material to best suit their needs. Depending upon the desired stiffness, weight, strength, flex, density, and tensile requirements, our engineers can work to develop the ideal composite. Composite products can be fabricated using glass fiber-reinforced plastics either in a mat/ roving (MR-GFRP) or unidirectional (U-GFRP) design. High performance carbon fiber unidirectional reinforcements are also available. Additionally, customers can choose from a variety of resins, including: polyester, vinylester, and epoxy.


Products have proven uses in the healthcare, industrial, electrical, consumer and recreational spaces where a high level of stiffness is desirable. Applications include:

  • Ballistic resistant panels (GlasArmor™) that allow for the retention of a projectile and prevention of hazardous ricochet, while also boasting durable, lightweight material
  • Wind turbine flex-beams are made from lightweight composites, but can withstand high centrifugal forces produced by the blades
  • Highway corrosion-resistant dowel bars have high flexural and transverse strength to increase the life of highways and to reduce maintenance costs
  • Trapezoidal beam reinforcements for vehicular bridges provide 15-20 percent increased stiffness compared to concrete bridges
