FRP Rectangular Tube Profiles, also known as Fiberglass Rectangular Tubes or GRP Rectangular Hollow Sections, are high-performance structural components manufactured through a continuous pultrusion process. Composed of continuous glass fiber reinforcements embedded in a thermosetting resin matrix, these FRP profiles offer superior mechanical strength, corrosion resistance, and long-term durability compared to traditional materials like steel, aluminum, or wood.
Engineered for versatility, FRP rectangular tubes are widely used in applications requiring strength, low weight, and resistance to harsh environments, such as construction, transportation, chemical processing, and industrial equipment frameworks.
Features of FRP Rectangular Tube Profiles
- Lightweight and High Strength:
These FRP profiles are up to 70% lighter than aluminum and significantly lighter than steel, yet maintain excellent tensile and flexural strength for structural applications. - Corrosion and Weather Resistance:
Resistant to acids, alkalis, moisture, and UV exposure, FRP rectangular tubes are ideal for outdoor or chemically aggressive environments. - Electrical and Thermal Insulation:
With non-conductive properties and low thermal conductivity, these profiles ensure safety and energy efficiency in electrical and high-temperature settings. - Dimensional Stability:
Thanks to their low coefficient of thermal expansion, FRP tubes maintain form and functionality under varying temperatures. - Easy Processing and Maintenance:
These FRP profiles can be easily cut, drilled, polished, or tapped with standard tools and require minimal maintenance over their lifespan. - Aesthetic and Customizable:
Available in multiple colors such as red, green, yellow, blue, grey, white, black, or custom shades to suit specific design or branding needs.
Applications of FRP Rectangular Tubes
- Structural Support & Framing:
Used as beams or crossbars in building frameworks and industrial enclosures. - Safety Guard Systems:
Ideal for protective fencing, handrails, and barriers around mechanical equipment. - Electrical and Telecom Structures:
Deployed in systems requiring insulation and electromagnetic transparency. - Transportation & Marine:
Used in lightweight, corrosion-resistant components for ships, vehicles, and bridges. - Chemical & Water Treatment Plants:
Reliable in corrosive settings such as chemical storage platforms and desalination systems.
