Hengshui Ruibin New Materials LLC proudly presents our premium Pultruded FRP Round Tube, engineered with a 50mm inner diameter and 6mm wall thickness. As a leading manufacturer established in 2019 with a factory spanning 1,000–3,000 square meters and a team of 101–200 skilled professionals, we specialize in producing high-strength, fire-retardant composite tubing suitable for demanding industrial applications. Our FRP round tube offers a reliable load capacity of 500 kg, making it an ideal choice for structural support, mechanical parts, and corrosion-resistant frameworks.
This product is manufactured using the pultrusion process, ensuring consistent fiber orientation and superior mechanical properties. The fire-retardant grade formulation enhances safety in environments where flame resistance is critical. Whether you need tubing for construction, transportation, or chemical processing, our FRP round tube delivers exceptional durability and performance.
Key Features & Specifications
- High Strength-to-Weight Ratio: Lightweight yet strong, reducing structural load while maintaining excellent load-bearing capacity.
- Fire Retardant Grade: Tested to meet common flammability standards (e.g., ASTM E84, UL 94 V-0 equivalent available upon request).
- Corrosion & Chemical Resistance: Withstands exposure to acids, alkalis, solvents, and moisture without degradation.
- Electrical Insulation: Non-conductive and non-magnetic, ideal for electrical and electronic applications.
- Low Thermal Conductivity: Helps maintain temperature stability in varying environments.
- Customizable Length & Color: Available in standard 6-meter lengths or cut to your exact requirements; color options include black, gray, and custom shades.
- 500 kg Load Capacity (Axial): Suitable for moderate structural support and mechanical parts.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum length you can produce for this tube?
A: We can produce lengths up to 6 meters in standard molds. Longer lengths can be custom-made upon request. -
Q: Is the fire retardant grade available in different classes?
A: Yes, we offer Class B and Class C fire retardancy per ASTM D635 and ISO 1210. Please specify your requirement. -
Q: Can this tube be used outdoors?
A: Absolutely. The UV-resistant grade is optional; standard tubes may require additional coating for prolonged direct sunlight, which we can provide. -
Q: How does the 500 kg load capacity vary with temperature?
A: The load capacity is tested at room temperature. High temperatures (above 100°C) may reduce strength; we recommend consulting our technical team for elevated-temperature applications. -
Q: Do you provide samples for testing before bulk order?
A: Yes, we offer sample pieces (subject to shipping costs). Contact our sales team for details. -
Q: What resin system is used in the fire-retardant grade?
A: Typically, a halogen-free polyester or epoxy with flame retardant additives. The exact formulation can be customized for your specific requirements. -
Q: Can the tube be machined (cut, drilled, sanded)?
A: Yes, FRP round tubes can be cut, drilled, and sanded using standard carbide tools. We recommend using dust control measures. -
Q: What is the lead time for a standard order?
A: For standard sizes and quantities (under 1000 pieces), lead time is typically 15–20 working days. Custom orders may require 25–30 working days.
