How does our spiral ducting work?

The difficulty that has been found, is that when you make a solid unit, this is generally done with a set of generalized sizes that are commonly used. With these, having one singular set made up that is of a different size can be quite difficult. With the spiral ducting technique, we can custom create a size that you need.


We found that there was a growing need in the industry for ducting that is flexible and tailor made for different sizes. This is why we decided to start supplying spiral ducting that offers the added benefit of being flexible, and the size you need. By doing so, we have opened the flood gates to a larger market that can now benefit from this.
