Guide to Precision Sheet Metal Fabrication

Metal Fabrication

Look around you. Many people never notice it, but many of the products and components we take for granted have some aspect of precision sheet metal fabrication. From paper clips to aerospace parts, and all types of finished products and parts in between, these goods start out as metal or alloy stock. The sheet metal fabricator machines punch, cut, drill, bend, remove and shape this stock into an endless number of forms.

Fabricators use their experience and mastery of a variety of processes, including welding, heat treating, adhesive joining, brazing and soldering, stamping and rolling, tumbling, buffing, polishing and honing. Fabricators take the customers’ desired material, the rate of production, the desired geometry and other physical requirements of the part or product to create an optimized, cost-efficient manufacturing process.

Companies across a broad spectrum of industries, products and service offerings require the expertise and services of companies that specialize in sheet metal fabrication, including:

– Rail Fabrication
– Railroad Containers, Equipment and Cars
– Aerospace
– Food and Beverage applications
– Trains, Trucks and Containers
– Modules and Parts for Motor Vehicles
– Automotive and Repair
– Shipbuilding and Repair
– Chemical and Pharmaceutical Manufacturing
– Boilers, Vessels and Carpentries
– Construction, Civil Engineering and External Maintenance
– Tubes and Other Semi-Finished Metallic Products
– Refining and Oil, and Coal and LNG Transportation
– Petrochemicals
– Utilities and Waste Management
– Maintenance and Turnaround Operations
– General Fabrication
– Custom Fabrication

Although commercial and industrial companies typically use metal fabrication services, they purchase customized metal parts for plants, warehouses, office buildings and other spaces. Some residential homeowners also have a need for customized metal fabrication services.

What Is Metal Fabrication?

about about metal fabricationWhen discussing the definition of metal fabrication, it helps to understand that metal is one of the most common types of raw material used in the manufacturing industry. The basic metal fabrication process forms, shapes and joins metal together through the removal or deformation of the material. Sheet metal stock has a thickness of between 0.006 and 0.25 inches, as compared to thinner metal called foil, and a thicker material called a plate.

The gauge describes the size or the thickness of the metal. Normal sheet metal stops around 7 gauge (3/16”, .1875”). After that it is usually measured by plate thickness with inches. Anything thinner than 7 gauge normally measured by “gauge.” For example, 12 gauge has a thickness of 0.1046 inches and weighs 4.375 pounds per square foot. A 24-gauge piece of sheet metal has a thickness of 0.276 inches and weighs 1.156 pounds per square foot. The Manufacturers’ Standard Gage set the criteria for the thickness levels for standard steel, stainless steel and galvanized steel.

The American Wire Gage (AWG) provides the Brown and Sharpe Gage used to determine the thickness and gauge for non-ferrous metals like brass and aluminum.

How Does Metal Fabrication Work?

Professional fabricators have a number of options available to create parts and products to specification and to also optimize the production process. Sometimes they must combine or build a complicated piece. The manufacturing process covers two primary categories: the removal process and deformation process. There are a variety of fabrication methods to produce the product.

The material removal process may consist of a variety of methods to remove some of the sheet metal material from the existing piece, including:

Cutting metal. The manual way of cutting metal with aviation snips continues to be one of the first tools fabricators use when working with metal fabrication. Power-scissors offer a way to cut metal more quickly and with less manual effort. Mechanical saw blades and laser beam technology are adequate for removing large amounts of material. A laser is especially effective on carbon steel, stainless steel and titanium, in addition to metals like aluminum and copper alloys that reflect light and conduct heat.

Machining. Fabricators remove material from a piece of sheet metal through machining – on a lathe, or by rotating the material against a cutting tool. Another option would be to use another cutting machine that has a rotating tool such as a drill. The number of axes in a machine defines the range of motion of the cutting head.

Punching. The punch-and-die tool operates similarly to a pair of scissors. The tool uses pressure to create a hole in the material and remove the slug or scrap. The punch produces holes and cut-outs of various shapes and sizes. The most common punched holes consist of geometric shapes like circles, squares and rectangles.

Blanking. This process removes a piece of material from the larger sheet and the desired part. Usually, fabricators blank multiple pieces in a single operation. Finished products range from jewelry to clock gears or watch components.

Stamping. This procedure works similar to punching, but instead of cutting, the die makes a raised portion of the material, without penetrating.

Shearing. The fabricator combines two tools to make a long cut on the sheet metal – one tool located above and one tool positioned below the sheet – to apply pressure to the material.

Nibbling. This process cuts a contour by creating multiple overlapping notches or slits in the metal, which allows the fabricator to form elaborate shapes. The punch comes in a variety of sizes and shapes, including oblong and rectangular punches, which minimize waste compared to a round punch.

When fabricators want to remove material without the need to create a deep hole, they use the milling process. The material removal stage constitutes the 2-D or shaping stage. The deformation process, such as bending or stretching creates a 3-D, complex shape.

The metal deformation or metal forming process utilizes applied force to a piece of sheet metal to alter its geometry rather than removing any materials. It alters the piece to achieve a certain design and includes:

Bending. Some sheet metal components require bending. Most fabricators use a brake press or press brake machine. This machine contains an upper tool called the punch and a lower tool called the die. It can operate manually or automatically. It consists of a set of dies that pinches the metal to form a crease. This operation has a limited number of uses because of the movement of the component and the possible configuration shape of the dies.

This method takes a flat sheet of sheet metal and bends or deforms the material to meet the intended design characteristics. A brake press along with the addition of manual computer numerical control (CNC) stops can specify the angle of the bend. The fabricator uses an overhead press, and a die set to both remove material and bend it in a single step.

Roll forming. This process shapes the sheet metal through a progressive series of bending operations as the sheet metal stock proceeds through a series of roll stations. As the machine forces the material through the roller dies, the metal deforms and bends. The process requires the use as a lubricant to minimize friction and reduce tool wear.

Spinning. Sometimes called spin forming, this metal fabrication method uses this process to fabricate cylindrical components by rotating a blank – a piece cut from the piece of sheet metal – while applying force to one side. This process produces a wide variety of products, including hubcaps, cookware, rocket nose cones, satellite dishes and musical instruments.

Deep drawing. Commonly used with ductile metals, such as aluminum, brass and copper, the deep drawing process stretches the sheet metal into the desired component shape. A tool places downward pressure on the sheet metal. The tensile force applied to the material causes it to deform into a cup-like shape. It is a common process to fabricate cans, cups, kitchen sinks, pots and pans fuel tanks, and automotive bodies.

Many custom fabricators use other methods to facilitate the material deformation process.

Metal Fabrication Materials

The material selection represents one of the most critical aspects of the sheet metal design processes because it affects design integrity as well as cost control. Choosing the best material for your project can seem overwhelming. Keep in mind that certain fabrication processes work best with certain materials. Strong, light metals work best because they allow you to re-engineer the profile to use less material but have a structurally strong product.

Most of the materials used in sheet metal fabrication consist of steel rolled into sheets of different gauges that have a protective coating, such as tin, zinc and black oxide. These coatings protect the metal from corroding and makes it last longer. Material options include:

  1. Galvanized sheet metal. This soft steel sheet has a zinc coating, which has a high resistance to rust. Good quality galvanized steel can undergo multiple bending and straitening without losing the protective zinc coating.
  2. Black iron sheet. This material, commonly used for products that require painting, has a thin coating of oxide that provides moderate protection against rusting.
  3. Aluminum sheet. Pure aluminum consists of a soft and ductile metal that has a whitish appearance. The appearance, light weight and with a high-resistance to corrosion, makes aluminum a popular choice for mass produced products, such as kitchenware, trailer parts and thousands of other small components. Customers can choose from various alloy content levels – 1000 series to 7000 series, for commercial products. The 1000 series consist of 99% pure aluminum.
  4. Stainless steel sheet. This material has an untarnished surface appearance and superior corrosion resistance. The material is easy to cut and weld without damaging the piece. Its resistance to corrosion makes it a popular choice for applications where the product requires high corrosion resistance. Stainless steel consists of high-grade steel with chromium and nickel additives. It has three classification levels based on the alloy content.

Galvanized sheet metal may be the most commonly used of all sheet metal materials. It can be used in most applications, including those that require welded joints. Other material options for custom metal fabrication include copper, brass, gold, iron, nickel and silver.

Sheet Metal Welding

After removal and formation of the material, the thickness of the material determines the next important part of the process: metal fusion. This is where two or more pieces of metal are joined together. For light and medium gauge metal, a mechanical seam will suffice. Heavier material requires a rivet or weld. Welding, which is the most common method for metal fusion, includes the following techniques:

  1. Oxy-Acetylene Welding. Although it is the oldest method, many people continue to use Oxy-Acetylene welding. It relies on tanks of oxygen and acetylene and an adjustable torch. The precise, controlled flame heats the metal, and the welder adds a filler rod to join the metals together. The method produces soft, pliable welds that are easily smoothed out with a hammer and dolly to get a flat weld joint.

  2. GTAW (Gas Tungsten Arc Welding), better known as TIG (Tungsten Inert Gas) Welding. This is the most used method by professional welders in the sheet metal industry. The torch has a non-consumable electrode, which generates a small, precise electric arc that melts the base metal. The fabricator adds a filler to the puddle of molten metal with the other hand. Fabricators prefer TIG welding because it offers more precision.

    Tungsten Inert Gas Welding Process

    The process of GTAW (Gas Tungsten Arc Welding), better known as TIG (Tungsten Inert Gas) Welding. TIG Welding is the most used method by professional welders in the industry.

  3. GMAW (Gas Metal Arc Welding), better known as MIG (Metal Inert Gas) Welding. MIG welding is the most common welding method because the method is easy to learn. This welding technique uses a motor that feeds the filler through the tip the MIG gun. When the wire touches the metal base, it completes the circuit, which melts the wire into the joint. This method, which is common for fusing together heavy sheet metal, also creates the hardest weld.

  4. Shielded Metal Arc Welding (SMAW), also known as Manual Metal Arc Welding (MMA), but best known as Stick Welding. Stick Welding uses a consumable electrode covered with a flux to lay the weld.

Other Considerations for Sheet Metal Fabrication Design

When beginning a brand new project, it is essential to have some concept of the design. It is not necessary to have the exact specifications for the final fabrication manufacturing. However, it helps to have a general idea of the finished product and some idea of the specific features and functions it needs to perform, as well as any dimensional constraints it requires. Some customers have a difficult time conceptualizing the product.

This is where an experienced metal fabricator can provide design services to demonstrate the possible design prior to beginning production. This will ensure an optimized sheet metal fabrication process. You should define what you want the product to do. Also, consider the functionality, the minimum and maximum length, durability, flexibility and other elements to begin creating the design.

Some other considerations for the design process include:

CAD prototype. After you determine the initial configuration for the custom metal fabrication design, a fabricator can generate it in a CAD program. This will create a 3-D rendering of the part or product. The software also produces 2-D schematics that can help customers visualize the product before the start of the manufacturing process. The CAD drawing can help you determine if the product is satisfactory. It will also provide a clear idea of what the product will look like without the need to have a prototype. Any noticeable issues are then corrected.

Tooling. If the custom metal work requires assembly, this step allows you to evaluate the first-run piece and make sure it functions properly. The final design for weld seams and fasteners can turn out different compared to final design and the CAD drawing. This should be addressed prior to the final production run. The solution may be to adjust the weld parameters or change the type of hardware. In addition, you can address any problem with tooling, such as adjustment of the calculation on the press brake, to meet the dimensions specified for the fabrication. After building the tooling, you can fabricate a first-run production work piece.

Tolerance. Some precision sheet metal fabrication products require a tight tolerance, which determines what process the fabricator will employ to manufacture the part. A wider tolerance allows the fabricator to use a low-cost production method and to produce the parts at a faster rate. Customers usually maintain tighter tolerance where needed and use a wider tolerance on nonessential features. This approach helps lower the overall manufacturing costs.

The customer should also determine if the product requires additional hardware or assembly before shipping. It pays to weigh these costs when deciding whether to provide hardware or pre-assembly. Calculate the quantity per batch because it affects tooling, raw material and design optimization and provides an accurate estimate of the total cost of the metal fabrication project.

Custom Metal Fabrication Services

Regardless of what stage you are in with a product development process, custom fabrication services can provide very valuable information at a critical stage of the development process. These services are useful whether customers choose to get help on a component assembly project or for a complete production. The following are typical custom metal fabrication services:

Design Services. This will help with the conceptualization creation analysis of parts and characteristics.

Build/Fabrication. This is the creation of the actual metal product.

Finishing and Assembly. Post-fabrication techniques and treatment required to improve quality and finish are completed with this service.

Many commercial and residential customers order custom metal products fabricated from a range of commonly used metals and their alloys.

    Thank you very much for sharing all of this information on metal fabrication. To be honest, it sounds like a very fascinating field. I think what sounds like the most interesting process is bending. I would imagine that being able to bend metal into different 2D and 3D shapes is very cool.

  4. McKayla Strauss says:

    I had no idea that sheet metal fabrication is used in so many different things! Food and beverage applications is probably the most surprising to me, since I don’t usually notice many things that involve any kind of sheet metal. I may have to look into that a little bit more to see exactly what ways sheet metal is used in that field.

  10. Steven Harrison says:

    A great deal more goes into metal fabrication than I anticipated. I hadn’t heard of galvanized sheet metal or black iron sheets. Many of the nuances go over my head, but believe me, you’ve raised my IQ by a few points… only a few though.

  11. Deanna R. Jones says:

    It’s interesting how tolerance affects metal fabrication. Using a wider tolerance on non-essential features seems like a smart way to make metal fabrication more cost effective, since it’s less expensive. I can see why tighter tolerance items would be needed though. That would be important if I needed metal to be made to last.

  12. Chris White says:

    I have know what metal fabrication is, but it is nice to have a better and fuller understanding of what it is. You even explain better of the ways that it is done too. This is something that I rather enjoy seeing and like to do as well. On top of all of that, you even list the materials that are used in metal fabrication too. There are so many different materials that are used in metal fabrication.

If it’s used for auto bodies, it should work for me.

  15. Logan Murphy says:

    I signed up recently for a metal work shop class so I have been trying to learn all I can about it. I find it really interesting how there are so many different types of metal. Like you mentioned, galvanized sheet metal, black iron sheet, aluminum sheet, and stainless steel sheet. I found all those steel fabrication materials interesting to learn about. I especially find it interesting that each metal has different qualities and reacts different from each other. Thanks for all the great information!

  16. Zach Thalman says:

    Thank you for explaining what metal fabrication is. I knew that it had something to do with making metal. I didn’t know that they fabricated metal into so many different things. Do they really still make railroad lines because I never really see the railways being used as much.

  17. Lilly Sedrick says:

    I had no idea that sheet metal was used in so many different products. It is really interesting to think that most everything we see has been a product of sheet metal manufacturing. It would be really interesting to be able to learn more about this field.

  18. Annie Marks says:

    I had no idea there were so many different techniques to do metal fabrication!

  21. Kael Drake says:

    I had no idea that there were so many things that sheet metal could be used for. In your post you mention that a steel fabricator can use steel to create or service anything from railroad containers to trucks. I think that this list will only continue to grow as new techniques for metal fabrication are discovered! What kind of future do you see for people working in the metal fabrication industry?

  22. Lauren Woodley says:

    Thank you for all of your insight! You talk about how some precision requires a tight tolerance, which determines what process the fabricator will employ to manufacture the part. I can see how knowing this will ensure that you’re using the right materials and the right processes, which will ensure that you always get the right results. Thus, this will make your work have more quality and more success. Thank you for sharing!

  23. Drew Harrison says:

    Making CAD prototypes must be extremely simplified with modern processes. Before it must have taken weeks to get the mold just right to be able manufacture something that was functional. Now, with GMAW and MIG, I bet it could be complete in a matter of hours. Thanks for this really detailed article about the metal fabrication process!

  24. Annie Marks says:

    That is awesome that you can shape metal into pretty much anything! Its interesting that there are so many different techniques for metal fabrication. I am glad that you displayed images of examples of metal fabrication, so that we could have a visual. Thank you for sharing!

    Thanks for sharing such a nice info with us. I appreciate this blog regarding Steel Fabricators

  26. Stewart Boomer says:

    I never knew there were so many different aspects to metal fabrication. Between steel sheets, welding, nibbling, shearing, stamping, punching, and bending, it seems like there’s a ton of things that I can do with metal that I never would have thought of. I’m looking at starting a project with a lot of metal involved, and now I have a ton of info on where to start! Thanks for sharing.

  27. Metal Fabrication says:

    You are providing very helpful information on Metal Fabrication Thank you

  28. Dee Francis says:

    It’s interesting how punch-and-die tools are used to remove scraps of metal. Using it to product holes and cut outs seems like it could be a good way to make different shapes out of metal. That seems good to remember if geometric shapes are needed for a steel fabrication project.

  29. Grace Turner says:

    Metal Fabrication seems like a very interesting process. I would like to see them take different pieces of metal through removing parts or deforming the material. Metal works always look so beautiful its hard to imagine they were deformed. Thanks for helping understand a little more about what steel fabrication is!

  30. Nathan Johnson says:

    I am beginning a project for my backyard and will probably need to get some custom metal fabrication. Because it’s going to be outside, I need something that can do well against the elements. I like that you said aluminum is “light weight and [has] a high resistance to corrosion”. I will probably look into using aluminum. Thanks for the tips!

  31. Vincent Burns says:

    There is so much that encompasses metal fabrication. I think it is really interesting how it isn’t just cutting metal and making it fit into a mold. It also is producing and making sure that everything is exactly how the buyer wants it to be. I also didn’t know that there were different methods to make iron.

  32. Jason Strong says:

    I think its so cool to see what can be done with metal now days. The idea of taking a material like metal and being able to make it into something useful is cool to me. It’s cool to see that these services are doing so well in the auto industry and I hope that they continue to have success.

  33. Marie Watson says:

    I didn’t realize that there are so many industries that rely on steel fabrication. It seems like it could be a great skill to have since it is used in so many different areas. It is also interesting that metal fabrication includes cutting, bending, and welding metal.

  34. Kyler Brown says:

    I’m taking some manufacturing classes right now. We’ve been discussing metal fabrication, so I just wanted to learn a little more in depth. This article was probably the best one that I have visited, and it really helped me learn some of the umbrella terms that are associated with fabricating. Thanks for sharing this.

  35. Patricia Anderson says:

    I’m surprised that one of the first tools that sheet metal workers use is aviation snips to cut. I thought they would start with machining or punching. My dad has just kind of gotten interested in metal fabrication. He has been talking a lot about it and I haven’t been able to understand. This made metal working a lot easier to understand so thank you!

  36. kiyel williams says:

    I had no idea there were so many different forms of machine fabrication. I think machining is the one I see the most and also seems the most intricate to me. I will have to talk to my friend about what he does in his shop. Thank you for the information!

  37. Lauren Woodley says:

    Thanks for all of the insight about bending. As you say, most fabricators use a brake press or press brake machine. Are these machines usually simulated so that it ensures accuracy or are these machines still manually used?

  38. April Cook says:

    This article is exactly what I needed. I heard someone mention metal fabrication the other day, and have been wondering what exactly it was. It was interesting to learn about the different methods of material removal. Do they use stamping to make metal sinks? Thanks for this great information!

  39. John Carston says:

    I’m researching metal fabrication for a project so I’ve found a lot of this information to be helpful. I like that you’ve provided a thorough definition of fabrication as well as a detailed explanation for how it works. I also appreciate the list of fabrication materials used as well. Thanks for the helpful post.

  40. Aimsaim says:

    Hey, great share……

    I really loved your post.

    I have recently become fascinated with metal work and how it is all done. There are so many aspects to it that just amaze me and I love seeing what people can do with it. This helped me see the difference between metal stamping, which is bending the metal, and metal fabrication, which is shaping the metal to do something. I can’t wait to keep learning about these processes and see if I can get into it.

  41. Kendall Everett says:

    I did not know that stainless steel has a superior corrosion resistance. It makes sense to produce a metal that will not corrode like other materials. Understanding all of the benefits of stainless steel would be an important motivator to fabricate it.

  42. JK Welding says:

    Nice and informative post! Thanks for sharing these useful information with us. I am glad to know about the stainless steel.

  43. Zequek Estrada says:

    I think you’re right that it would help the fabrication process to have a general idea of the finished product. Not everything always goes according to plan. I think that’s fine as long as the product comes out according to how it was planned to be like.

  44. Ronny Howard says:

    My brother was telling me a little bit about metal fabrication the other day but I didn’t fully understand it. Cutting metal with aviation snips seems to be the easiest way. It is nice that power-scissors offer a way to cut metal more quickly and with less manual effort like you mention.

  45. Jalu Sakti says:

    Wow, thanks for providing such a clear explanation of what metal fabrication is and all the instances it is used. I’ve actually heard of oxy-acetylene welding before — I think I learned about it in school. I’m glad you talked about stainless steel fabrication. I am a big fan of the look of stainless steel appliances!

  46. Georgia Boothe says:

    I had never thought about the process of stainless steel fabrication. I can see why it would be a popular choice for applications since it is such a useful material for so many kinds of projects. It’s great that it is also easy to cut and weld without damaging it.

  47. Annika Larson says:

    The metal stamping and fabrication is such an interesting field to me. I didn’t realize that the material selection is such a critical aspect of the process, but that makes sense. We will have to see what metal would be most beneficial for our next project including stamped metal.

  48. lenny strin says:
