Fluted Aluminium Tube

The fluted aluminium tube is the most flexible model in the semi-rigid aluminum duct series, featuring a unique 9-corrugation structure that inherits pure aluminum's high-temperature resistance and flame retardancy while offering superior axial stretch, compression, and bending performance. Designed for exhaust scenarios requiring extreme installation offset, frequent disassembly, or complex 3D paths-such as dynamic connections between large commercial kitchen range hoods and main flues, exhaust interfaces for industrial production line equipment, and ventilation systems with limited maintenance space-the product's extra corrugations provide greater deformation capacity and longer stretch stroke, making it a professional duct for high-standard flexible connection needs.

Crafted from high-purity aluminum strip via precision rolling, the fluted aluminium tube boasts uniform, repeatable corrugations, ensuring shape recovery after repeated deformation and excellent resistance to metal fatigue. Its metal-sealed structure eliminates air leakage risks, with outstanding high-temperature resistance suitable for most medium-high temperature exhaust environments. Installation requires no special tools-simply bend and stretch the product by hand to the desired length, greatly improving efficiency and adaptability. In ventilation projects needing frequent adjustments, inspections, or complex structure penetration, it offers unparalleled installation convenience and long-term reliability.

We recommend the fluted aluminium tube for commercial catering exhaust, industrial process exhaust, laboratory ventilation systems requiring extreme flexibility, and any occasion needing large-range displacement compensation. Its enhanced flexibility provides greater freedom in system design. If you face harsh installation conditions or dynamic connection needs, the product is the key component to solve your challenges.
