Since 1956, Strongwell has been manufacturing high quality fiber reinforced polymer (FRP) products using "the continuous automatic process" (today known as "pultrusion").
Strongwell is recognized as the world's leading and largest pultruder of FRP.
Harrington carries an extensive product line from Strongwell, showcasing their dedication to meeting diverse requirements across various industries. Strongwell specializes in pultrusion, an efficient manufacturing process that produces continuous lengths of reinforced polymer structural shapes with consistent cross-sections. This process involves using a liquid resin mixture containing resin, fillers, and specialized additives, combined with flexible textile reinforcing fibers. These raw materials are pulled through a heated steel forming die using a continuous pulling device, distinct from the extrusion process where materials are pushed through a die.
The Pultrusion Process
The reinforcement materials utilized in pultrusion, such as rolls of fiberglass mat and doffs of fiberglass roving, come in continuous forms. As these reinforcements are pulled through the die and saturated with the resin mixture, the resin undergoes gelation, or hardening, initiated by the heat from the die. This results in the formation of a rigid, cured profile that corresponds precisely to the shape of the die, ensuring consistent and accurate cross-sections in the final product.
Strongwell’s expertise in pultrusion enables them to produce high-quality reinforced polymer structural shapes for diverse applications across industries. Their commitment to excellence and innovative technology cements their position as a leading global provider of advanced composite materials. With Harrington’s support, customers have access to a comprehensive range of reliable solutions to meet their specific needs in demanding environments.

Why Choose Fiberglass
What is Fiberglass Reinforced Polymer?
Product Range
Strongwell has by far the world’s largest array of proprietary fiber reinforced polymer (FRP) pultruded structural products including standard structural shapes, plate, grating, planking, handrail systems, building panels, ballistic resistant plate and systems, power poles, nuts and bolts, cooling tower components, ladder rail, and tool handles. The company also has hundreds of active customer-owned sets of dies and tooling for custom parts, some of which are available for use with a small royalty to the die owner. The extensive product range means more products to sell, and more products to choose to optimize solutions.
The Features of Strongwell’s Fiberglass Composites
High Strength
Stronger than structural steel on a pound-for-pound basis. Used for building structures, walkways, platforms, etc.
Light Weight
Strongwell’s fiberglass composite products weigh approximately 75-80% less than steel and 30% less than aluminum. This translates to lower transportation costs, easier installation and less weight in structural designs.
Corrosion Resistance
Strongwell’s proprietary “wet-out” process ensures complete reinforcement saturation. Fiberglass will not rot and is impervious to insects and a broad range of corrosive environments. Strongwell FRP composites have been successfully used for indoor and outdoor applications at hotels, restaurants, chemical plants, water and wastewater treatment plants, and in many other corrosive environments.
Low Conductivity
An excellent insulator, fiberglass has low thermal and electrical conductivity, making it a popular choice in electrical applications.
Electromagnetic Transparency
Fiberglass is transparent to radio waves, microwaves, and other electromagnetic frequencies. Strongwell composite products are
regularly used in cellular applications due to this feature.
