Stainless Steel Metal Duct System
Step 3: Cutting Technique During Sheet Metal Duct Fabrication
At this point, you will cut sheet metal to appropriate size and dimensions.
This will depend on the shape of sheet metal duct you need.
Depending on your capability, you can use any of the following:
This entails burning through the sheet metal to form accurate cuts.
Also, no contamination will occur as there is no physical contact with the sheet metal.
No warping occurs during laser cutting and leaves a clean and consistent cut.
Laser cutting is fast and eco-friendly as it uses less energy than other cutting methods.
This method will use hot plasma to cut sheet metals.
The plasma operates at a high speed in a specific jet stream to make accurate cuts.
It is affordable to conduct thus making it a popular choice.
Also, it is quick but not as quick as laser cutting.
Plasma Cutting of Sheet Metal
This method entails using high-powered water jets to cut through sheet metal.
Therefore, it will not leave heat zones on the sheet metal.
Waterjet cutting is precise and leaves a clean finish on the sheet metal.
The two methods you can use are abrasive jet and water-only or pure waterjet cutting.
This is a less accurate method of cutting thus not suitable for detailed small cuts
It is suitable for cutting large sheet metals from large rolls to small manageable sizes.
Also, you will use blades to make the cuts that are parallel to the other cut edge.
Also, you cannot make angled cuts.
This is a technique of cutting out metal pieces from sheet metal.
Here, you will apply force to remove the area from the sheet metal thus leaving out a hole.
Also, you will punch out geometric shapes and the size you can punch out is not limited.
However, it will not leave behind clean edges which you need to smooth out later on.
In this process, the pieces you punch out are used in other processes whereas the other part of the sheet metal is scrap.
Step 4: Forming Techniques In Sheet Metal Duct Fabrication
Here, you will bend the sheet metal to form appropriate duct.
It is important to understand the various forming techniques that you will use in sheet metal duct fabrication.
Besides, these forming techniques assist in transforming flat metal sheets into a three-dimensional metal duct with functional parts.
Here are some main forming techniques in sheet metal duct fabrication:
This is a cold-forming technique that will transform flat sheet metal into different shapes for the duct fabrication process.
In the stamping process, you will use a tool and a die.
It entails impacting the tool and die on sheet metal to change the form of the metal when you use shear pressure.
Stamping is a broader terminology when you are referring to sheet metal duct fabrication.
It will include bending, embossing, as well as punching.
Furthermore, it includes flanging, which involves swiping the sheet metal until it forms flanges.
This is another important step in sheet metal duct fabrication that changes its shape and not its volume.
As the name states, it entails bending the sheet metal into the required shape for the fabrication process.
Some pieces of equipment that metal fabricators will use when bending include rolling machines, press brakes, etc.
For instance, press brakes will force the sheet metal between the vee-shaped lower tool and the knife-edge upper tool.
This will form the sheet metal to the appropriate angle to lengths of up to 10 m long.
This equipment will form standard shapes like U shape, channel shape, or V shape when conducting sheet metal duct fabrication.
Bending may seem like a simple process to an untrained eye but it is rather a complex technique requiring an expert fabricator.
This is mainly due to the possibility of spring back occurring.
Spring back is a terminology that describes a metal that tries to retain its original flat-shaped structure following the bending process.
Sheet metal duct fabricators combat this issue by over bending the component.
Bending Of Sheet Metal Duct
This allows the spring-back angle to take the appropriate angle for the sheet metal duct.
Bending is the most cost-effective sheet metal duct fabrication process besides being highly versatile.
This is a technique you will use when you want to form holes during sheet metal duct fabrication.
Punching works with a punch and a die which is made of hard metals.
The materials will apply shear force for it to make holes into the sheet metals.
Afterward, the die will gather the scrap metal that you have created from punching the hole on the sheet metal.
The punching process can assist you to form indentations within the sheet metal.
There are punching machines that can make holes that have a diameter of about 50 mm.
Punching In Metal Duct Fabrication
This is a process you will use when you desire to form smooth curves during sheet metal duct fabrication.
For instance, you should use a roll forming method when fabricating shapes like cylinders, rounded architectural structures, or cones.
During the rolling process, you will pass the sheet metal duct via several roll systems until you attain the desired curve and width.
Rolling Sheet Metal Duct
In this sheet metal duct fabrication process, you will raise or sink the sheet metal design by passing it through rolls with patterns.
Some fabricators can also polish and weld the edges of the sheet metal duct to form a high-quality surface finish.
An Embossing Machine
Step 5: Assembly Processes In Sheet Metal Duct Fabrication
Assembling is the process of joining pieces that you have cut and formed.
Also, you can perform the assembly process either manually or automatically.
Besides, you can conduct sheet metal duct fabrication assembly through the following methods:
This is the process of joining separate components together.
Examples of welding techniques you can use during sheet metal duct fabrication include:
- Spot welding

This stands for Tungsten Inert Gas.
It is a suitable welding method where you can join the majority of metals to high standards.
This stands for Metal Inert Gas.
Besides, it is suitable for welding mild steel and is a cost-effective method for heavy structures.
- Stick welding.
TIG Welding In Progress
Use threaded fasteners, rivets, or adhesives.
This technique will join two or more parts by binding them together.
For instance, you may drill holes between the two parts and secure them with fasteners or rivets.
This is a popular way of assembling sheet metal ducts as they are simple to accomplish and are affordable.
Also, you can seal the seams of the sheet metal duct at its connections with substances such as:
- Metal tape
- Rubbery duct sealant
However, you should steer away from using standard duct tape since the adhesive will dry out after a while thus breaking the seal.
Sheet Metal Bending
Clinching And Bonding
One way you can join sheet metal ducts without using rivets, bolts, or screws is through clinching.
This is a way you can use to save costs.
Besides, it will not produce heat, fumes, or sparks and you can use it to join dissimilar parts.
Other techniques may include riveting and bonding.
The choice of bonding or assembly technique will depend on the type metal duct.
Step 6: Check And Test Quality After Sheet Metal Duct Fabrication
This entails ensuring the sheet metal duct conforms to quality standards and meets the design specifications.
Some methods you can use to test the quality of sheet metal include:
- Tensile strength
- Fatigue test
- Hardness test
- Hole expansion test
The cost of metal sheet duct fabrication depends on a lot of factors such as:
- Material construction
- Assembly method
- Cutting method
Of course, other factors such as custom features and finishing requirements may also determine cost of sheet metal duct fabrication.
