Fluted Tubes

FRP fluted tubes are round or square profiles with longitudinal grooves or flutes along their length. The fluting adds rigidity and a decorative texture. Like all FRP shapes, fluted tubes remain corrosion-proof and non-conductive. They are often used for architectural columns, light diffusers, or where a larger surface area (for painting or traction) is desired.

Key Features

Ribbed exterior (increases moment of inertia slightly, adds grip)
Durable composite construction (no corrosion or delamination)
Non-slip profile (good for columns you may climb onto)

Benefits

Aesthetic appeal (modern ribbed look) while maintaining FRP benefits
Functional texture (preferred on ladders or railings for anti-slip)
Easy to paint or finish (additional mechanical interlock from grooves)

Applications

Architectural column covers (fountain or atrium columns)
Safety railing posts or bollards (improved handhold)
Lighting column poles (fiberglass is electrically safe around wiring)

Technical Specifications

Grooves typically spaced 5–10 mm apart, up to 2 mm deep
Profile dimensions as per design (e.g. 50 mm round × 50 mm length with flutes)

Unique Selling Points (USPs)

Combines decoration and strength (versus plain tubes)
Retains all FRP safety features (insulating, lightweight, maintenance-free)
