Duct Fabrication

When looking at duct-work, one does not think about all the work that goes into building them. Sheet metal fabrication is an art in itself and requires special training to make sure the ducts are solid and will carry the HVAC air through a system with no leaks.


What Are the Types of Air Ducts? 

Ducts are used to provide a passage for ventilation, heating and air conditioning. When properly installed they assure quality air is delivered to the interior of any home or building. Having good, solid ducts is essential if a quality air is to be maintained. They must be able to supply air, return it and exhaust it.

Galvanized mild steel is most traditionally used in building ducts. It has a zinc coating which prevents the duct from rusting. Fabricating shop ducts can be made in various shapes to suit special situations.

These ducts are, as a rule, fabricated with duct wrap to make them quieter and eliminate the loss of hot or cold air that would occur without insulation. Some duct-work manufactured today has rigid insulation panels that do not need further lining and can be instantly fashioned and installed. This protection against air loss provides a cost-effective operation with lower utility bills.

Aluminum duct-work is popular because it is lightweight, which makes it easy to install. Sheets of aluminum used are ordinarily pre-insulated panels. After cutting to size, sections of the duct are put together with glue and aluminum tape is applied to the seams.

Duct Fabrication: FAQs

A duct is an insulated tube or a channel to carry airflow from one area to another.
Duct Fabrication is the bending of sheets precisely and cutting them into desired shapes. These shapes are calculated by design software to deliver adequate airflow.
Ductwork is an insulated tube or channel to transport air from one location to another to distribute heating or cooling evenly. They are installed in residential and commercial establishments.
There are three types of ducts: flexible, semi-rigid, and rigid. Flexible ducts are round tube-like and can be placed anywhere. Rigid ducts are Pre insulated Sheets, and GI ducts must be fabricated and installed using support.
Preinsulated Aluminium Sheet and Galvanized Steel Sheet.
The maximum length of the running duct can be 50 linear feet for optimum. Anything more than that will reduce the airflow.
Duct Leaks are when the air escapes the duct channel resulting in a loss of cooling.
The easiest way to check for leaks is to walk along the ducts and observe for any cuts or holes. If there is any noticeable hole, get in touch with an expert ductman to fix the leak.
Yes, duct insulation is necessary. If you have no leaks, that's great! We have resolved one problem. Its good to insulate your ducts so you don't lose cooling when the air is transported from one area to another.
Typically, there are two types of materials used in HVAC ductwork: Preinsulated Aluminium Sheet and Galvanized Steel Sheet.
Several components make ductwork. -Vibration Isolators -Volume Control Dampers -Smoke Dampers
