Reliable FRP Rectangular Tubes from a Trusted Manufacturer
Hengshui Ruibin New Materials LLC, established in 2019 and operating from a 1,000–3,000 m² factory in Hebei, China, delivers pultruded FRP rectangular tubes that meet strict performance standards. Our FRP Rectangular Tube 2x1 inch with 1/8 inch wall is compliant with ASTM D3918 and offers excellent UV resistance and heat resistance up to 120°C. These tubes are engineered for demanding environments where corrosion resistance, electrical non-conductivity, and dimensional stability are critical. With an annual export value exceeding US$2.5 million and a skilled team of 101–200 employees, we ensure consistent quality and timely delivery to markets across North America, South America, Europe, Asia, and beyond.
Key Features & Technical Specifications
- Precise Dimensions: 2 x 1 inch outer cross-section with a 1/8 inch wall thickness, manufactured to tight tolerances for easy integration into structural assemblies.
- ASTM D3918 Compliance: Designed and tested in accordance with ASTM D3918 – the standard specification for pultruded fiberglass-reinforced plastic shapes, ensuring mechanical reliability and consistency.
- UV Resistant Formulation: Incorporates UV-stabilized resin and optional polyester veil, protecting the tube from degradation when exposed to sunlight for extended periods.
- 120°C Thermal Resistance: Suitable for applications where continuous operating temperatures reach up to 120°C, such as near hot machinery or in cooling towers.
- Corrosion & Chemical Resistance: Inherently resistant to moisture, salts, acids, and alkalis – ideal for wastewater treatment, marine, and chemical processing environments.
- Electrical Non-Conductivity: Provides electrical insulation, making it safe for use in electrical substations, cable trays, and other sensitive areas.
- Lightweight yet Strong: Approximately 70% lighter than steel with comparable strength-to-weight ratio, reducing transportation and installation costs.
- Customizable Length & Color: Available in lengths from 1 to 12 meters and standard colors (gray, black, green) or custom colors per customer request.

Frequently Asked Questions
-
Q: Can this FRP tube be used outdoors continuously?
A: Yes, the UV resistant formulation and optional veil protect the surface from sunlight degradation. For extreme outdoor exposure, we recommend adding a UV stable coating for extended life. -
Q: What is the maximum span for loading with this 2x1 inch tube?
A: The load capacity depends on span and support conditions. For a simple support span of 1 meter, the tube can typically handle a uniformly distributed load of approximately 80–100 kg. Please contact our engineers for specific calculations. -
Q: Is this product suitable for food processing environments?
A: FRP is generally inert and can be used in areas where food-grade stainless steel is not required. However, for direct food contact, please check local regulations or request a special resin formulation. -
Q: Do you provide custom colors?
A: Yes, we can match Pantone or RAL colors. Minimum order quantity may apply for custom colors. -
Q: How is the tube packaged for export?
A: Tubes are bundled with protective wrapping (stretch film, corrugated cardboard, or wooden crates) to prevent damage during transit. We can also customize pallet designs for your convenience. -
Q: What is the typical lead time for standard sizes?
A: For standard 2x1 inch tubes and common lengths, lead time is 10–15 working days after order confirmation. Large orders or custom colors may require 20–25 days. -
Q: Does the tube meet any fire retardancy standards?
A: Our standard polyester resin offers a flame spread index of 25 or less per ASTM E84 (Class A). For higher fire resistance, we offer halogen-free phenolic resin as an option upon request.
