Durable and Aesthetic Pultruded GRP and Fibreglass Structural Shapes
Our composite structural profiles are predominantly stocked in a standard grey color based on RAL 7001. For projects requiring a different aesthetic, we also offer profiles in yellow (RAL 1023). We ensure color consistency by monitoring the CIELAB Delta E, providing a product that is not only functional but also visually appealing.
Safety and durability are key features of our pultruded profiles. These fiberglass structural shapes are certified with a fire rating of EN 13501-1 Euroclass E, ensuring peace of mind in demanding applications. Additionally, our GRP pultruded profiles exhibit exceptional chemical resistance: they do not rot and are impervious to a wide array of corrosive environments. For applications requiring enhanced chemical resistance, we offer profiles made with vinyl ester resin. Detailed information is available in our corrosion resistance guide, or you can contact us to discuss your specific requirements.
Our structural profiles and FRP shapes are manufactured using the pultrusion process, an efficient and continuous method for producing composites. This technique ensures consistent quality, high-volume production capabilities, minimal waste, and reduced labor costs. As a result, each structural profile and shape maintains superior performance and durability, effectively meeting the diverse needs of various industrial and commercial projects.
Advantages of Structural Composite Profiles for Construction and Infrastructure
Durable – UV and Chemical Resistance: Fiber-reinforced composite profiles resist UV radiation and various chemicals, maintaining their structural integrity and appearance in harsh environments for long-lasting durability.
Lightweight – 4 Times Lighter Than Steel: Exel’s composite profiles are up to four times lighter than steel while offering equivalent strength, making handling, transportation, and installation easier and more cost-effective.
Strong – Exceeding Strength Requirements: Our structural composite profiles typically offer double the strength required by the E23 classification, ensuring robust and reliable structural support under demanding conditions.
Stiff – High Tensile Modulus: With a tensile modulus typically exceeding the E23 classification by 25%, composite structural profiles provide superior stiffness, maintaining shape and structural integrity under load.
Low Thermal Conductivity – Excellent Insulation: Fibreglass structural shapes exhibit low thermal conductivity compared to metal, enhancing insulation and energy efficiency by minimizing heat loss.
Thermal Efficiency – Minimizing Heat Loss: The thermal efficiency of our pultruded profiles reduces heat loss, contributing to energy conservation and lower heating and cooling costs.
Thermally Stable – Low Coefficient of Thermal Expansion: Our standard structural profiles have a coefficient of thermal expansion six times lower than uPVC and half that of aluminum, ensuring minimal expansion and contraction with temperature changes.
Low Electrical Conductivity – Insulating Properties: Made with glass fiber, our profiles have low electrical conductivity, ensuring safety in applications requiring electrical insulation.
Dimensionally Stable – High Stiffness and Thermoset Resin: The combination of high stiffness and thermoset resin ensures our profiles maintain their integrity and performance over time, even under varying environmental conditions.
Corrosion Resistant – Weathering Resistance: Pultruded structural profiles resist weathering, corrosion, and chemical exposure, extending their lifespan and reducing maintenance needs.
Low Maintenance – No Rot, Rust, or Swell: Unlike traditional materials, composite profiles do not rot, rust, or swell, resulting in reduced maintenance costs and less frequent interventions.
Lasting Performance – Moisture and UV Resistance: Moisture-resistant and UV-stabilized, our structural profiles and shapes ensure consistent long-term performance.
Non-Magnetic and Radio Frequency Transparent: Non-magnetic and radio frequency transparent, our profiles are ideal for applications where minimizing electromagnetic interference is important.
Machinable: Easily machined using standard equipment, our composite profiles offer versatile customization and easy project integration.
Easy Installation: The lightweight nature permits lifting into position with less equipment.
High-Quality Pultruded GRP and Fibreglass Structural Shapes Meeting European Standards
Our profiles are crafted from high-quality glass fiber combined with a UV-stabilized isophthalic resin. This innovative construction process involves using direct glass rovings, constructed mats with off-axis fiber, and a polyester surface veil. These meticulous manufacturing techniques ensure that our profiles adhere to the rigorous European Standard EN13706 E23, with profiles less than 5mm thick meeting the E17 criteria. Understanding the standards like EN 13706 and E23 is crucial.
EN 13706 outlines the prerequisites for structural pultruded profiles, especially where load-bearing characteristics play a pivotal role in design and function within a load-bearing system. The E23 classification signifies a minimum Full Section flexural modulus of 23GPa and an average axial tensile modulus of 23GPa across five valid tests. Our profiles not only meet but often exceed these minimum requirements, typically achieving a modulus of 30GPa and an axial tensile strength of 500MPa (considerably higher than the minimum requirement of 240MPa)
