How are sheet metal ducts made?
Rectangular metal ducts are built by putting two pieces of bent sheeting together. The flat pieces of metal are first cut to the desired size with a cutting machine or plasma cutter. Then, another machine folds the sharp edges inward. Thirdly, the sheet is shaped into an L or a tube.

What is ductwork fabrication?
Sheet metal duct fabrication involves cutting and forming processes. Cutting uses shears and specialty high-definition plasma equipment, and forming uses brakes and presses to exert applied force to shape the material.
What kind of ductwork is best?
Though there are different types of ductwork available in the market today, Sheet metal is most recommended as this type of air duct is non-porous in nature and thus does not allow mold or bacteria breed in the air ducts. Sheet metal ductwork also helps you prevent potential health risks of fiberglass air ducts.
What machines are used to cut sheet metal?
Shearing Machine: It is a machine that is used for cutting sheet metal.
What gauge steel is duct work?
height

What is a duct machine?
DuctZipper-V Ducting Machine: Professional air ducts The RAS DuctZipper-V ducting machine forms and closes the seamed joint on small and medium size air ducts. Professional air ducts can hardly be produced faster, more easily and more economically.
Is sheet metal part of HVAC?
In the HVAC industry, sheet metal is the most common material used for ductwork and HVAC systems, beating out other materials like polyurethane and fiberglass.
Rectangular metal ducts are built by putting two pieces of bent sheeting together. The flat pieces of metal are first cut to the desired size with a cutting machine or plasma cutter. Then, another machine folds the sharp edges inward. Thirdly, the sheet is shaped into an L or a tube.
What is fabricated sheet metal used for in HVAC?
Fabricated sheet metal is commonly used in the ductwork of HVAC systems. Traditional ductwork is installed in commercial and industrial buildings for the heating and cooling systems. Sometimes, however, the regular metal ductwork must be routed in odd ways, due to various obstacles in the path. Longer piping would be added to get the metal fittings and tubes installed to go around all those barriers.
What is precision sheet metal?
Significantly, precision sheet metal fabrication describes any type of metal that be stretched out and manipulated into a metal sheet and then assembled into a product.
What is a fab sheet?
