Aluminium Ducting Hose (Semi-Rigid)

Aluminium Ducting Hose (Semi-Rigid)
The Aluminium Ducting Hose Semi-Rigid is a heavier-walled corrugated aluminium ducting hose that holds its shape better than fully flexible aluminium ducting — providing a more permanent installation feel while retaining enough flexibility for bends and direction changes. The thicker corrugated aluminium construction offers improved dent resistance, better airflow characteristics, and a longer service life compared to standard flexible aluminium ducting. Temperature rated -30°C to +250°C with full fire resistance. Available from Flytech Engineering Sdn Bhd with ready stock in Klang, Selangor.

Frequently Asked Questions
Q: What is the difference between flexible and semi-rigid aluminium ducting?
A: Semi-rigid aluminium ducting uses heavier wall corrugated aluminium that holds its shape better than thin-wall flexible aluminium ducting. It provides a more permanent installation appearance, better dent resistance, improved airflow characteristics, and longer service life — at slightly higher cost. Flexible aluminium is preferred for temporary installations or applications requiring maximum flexibility.

Q: When should I choose semi-rigid aluminium ducting?
A: Choose semi-rigid aluminium ducting for permanent installations where the duct should hold its shape long-term — kitchen range hood exhaust, dryer vents in commercial buildings, HVAC duct that will not be repositioned, and applications where appearance and dent resistance matter.

Q: What sizes are available?
A: Available in diameters from 100mm to 500mm with ready stock at Flytech Engineering in Klang.

Q: Is semi-rigid aluminium ducting still flexible?
A: Yes — semi-rigid still allows bending and direction changes for installation. It just holds its shape better than thin-wall flexible aluminium once installed. Easier to install in long straight runs.

Q: Where can I buy semi-rigid aluminium ducting?
A: Available from Flytech Engineering Sdn Bhd in Klang, Selangor with ready stock. Contact us for pricing and installation guidance.
