Aluminum Flexible Duct Standard and Customized sizes

Aluminum flexible duct is the most common ventilation duct on the market. It has a high shrinkage ratio so it can be transported and stored in compressed volume, which saves transportation costs and facilitates installation.

The duct connection method makes installation more convenient and is not limited by the installation location and direction.

It uses aluminum foil and stainless steel skeleton as its material, which can effectively prevent corrosion and long-term use. It provides a variety of different lengths and diameters according to customer needs.

We also provide the aluminum flexible hose that combined with other materials such as PVC and glassfiber can improve the performance of the product. For longer service life, for better anti-scratch, and more durable usage.
