Key features

Integrated Seamless Design: Produced via tube rolling and compression molding without welding seams for superior structural integrity.

Ultra-Lightweight Construction: Significantly reduces carriage weight and axle load compared to traditional steel or aluminum handrails.

Zero Corrosion Risk: Chemically inert carbon fiber resists rust, oxidation, and humidity without requiring anti-rust maintenance.

High Wear Resistance: Dense outer composite layer prevents scratches and peeling from frequent passenger friction and grabbing.

Customizable Dimensions: Thickness and dimensions are fully customizable to meet specific rail transit project requirements.

Superior Rigidity: Hollow tubular design maintains high circumferential rigidity and bending resistance under heavy loads.

Fire Safety Certified: Meets FAR 25.853 Appendix F and UL94 V-0 standards with self-extinguishing and low smoke properties.

Comprehensive Post-Processing: Available for cutting, drilling, polishing, painting, and edge sealing to fit precision assembly needs.

Product Q&A

Q:Will the carbon fiber handrail surface wear out quickly after long-term passenger grabbing?

No. The compact fully cured composite outer layer has outstanding wear resistance. Frequent friction from passengers' palms and daily contact will not leave deep scratches or damage the base material. Unlike metal handrails whose surface coating peels off easily, the integrated textured surface stays intact for years of service and maintains a tidy interior look.

Q:Does the hollow tubular carbon fiber rod lose supporting strength under heavy leaning load?

It retains reliable bending resistance thanks to optimized continuous fiber winding layout. Though hollow to realize lightweight, the whole tube body bears force evenly. When passengers lean on or grip the handrail tightly, no permanent deformation or bending sag will occur, fully meeting the daily dynamic load standard of transit passenger compartments.
