Product Overview

Huangang pultruded FRP square tube is high-performance hollow box-shaped fiberglass structural profile produced with mature continuous pultrusion forming technology in Henan, China. The raw material is reinforced FRP/GRP fiberglass composite, delivering superior mechanical strength, anti-corrosion performance and environmental friendliness compared with metal square pipes. We support full custom production: customized cross-section size, wall thickness, cutting length and arbitrary exterior colors as client requirements, the finished profiles keep original smooth composite surface without secondary surface processing. Our fiberglass box tubes adopt strict raw material inspection and continuous pultrusion forming process to guarantee stable uniform high quality, ideal lightweight anti-rust structural substitute for steel square tubing in corrosive working environments such as chemical plants, sewage treatment facilities, coastal construction and mine support projects.

Core Product Advantages

1. Continuous Pultrusion Stable Molding Technology

   Adopts integrated pultrusion forming process, uniform fiber distribution inside the square tube wall, consistent tensile, bending and compressive strength for each finished box profile.

2. Outstanding Anti-Corrosion & Anti-Rust Property

   Unlike steel square pipes, FRP fiberglass square tube resists acid, alkali, salt water and chemical solvent erosion, no rust or oxidation even in long-term coastal and chemical workshop service.

3. Lightweight High Strength Structural Performance

   Much lighter than equivalent metal square tubing while maintaining high structural rigidity, effectively reduce overall load weight of construction frames and transportation equipment.

4. Full Multi-Dimension Customization Support

   Clients can freely customize inner & outer square size, wall thickness, cutting length and surface color, match unique structural design demands of different engineering projects.

5. Eco-Friendly Composite Raw Material

   Non-toxic, low thermal conductivity, anti-aging FRP composite material, no heavy metal pollution during production and long-term outdoor service life.

6. Natural Smooth Original Surface

   No secondary polishing, coating or film treatment required, the raw composite surface has self-cleaning performance and stable color fading resistance.

7. Long Service Life Low Maintenance Cost

   Does not require regular anti-rust painting maintenance like metal pipes, cut long-period operation and upkeep expenses for factory and construction projects.

8. Wide Cross-Industry Application Compatibility

   Suitable for building load-bearing frames, chemical equipment support brackets, marine platform structures, greenhouse skeleton, sewage tank support frames and mining anti-corrosion supports.

Wide Application Scope
