Understanding Sheet Metal Fabrication
Sheet metal fabrication transforms flat metal sheets—like stainless steel, aluminum, or copper—into three-dimensional structures. This transformation happens through cutting services, bending, forming, and assembling.
These processes often overlap to create the final product. The versatility and precision of sheet metal make it ideal for projects demanding accuracy and durability. You can expect business days as the turnaround for many projects and if you need standard lead times those can be obtained upon request.
The Sheet Metal Fabrication Process: A Step-by-Step Guide
1. Design
The design phase uses sketches, 2D/3D models (using CAD software), and material selection. Manufacturing process planning considers intended use, dimensions, tolerances, and finishes.
Proper project planning is important to ensure the correct sheet thickness and that there is no warping when doing complex sheet metal forming. This stage sets the foundation for the entire project. The sheet metal design needs to be done well and should encompass metal design principles to ensure simple parts are functional as well as production parts when required.
2. Cutting
Laser cutting, a precise method, often begins the fabrication process. A laser cuts through sheet metal material, and allows for precise cut parts, and creating a variety of other sheet metal parts with CNC machining. For thicker sheets or non-metal materials, waterjet cutting offers flexibility and extreme accuracy.
Plasma cutting is a cheaper alternative than Waterjet cutting but offers less precision when you need accurate material cutting done with rolled steel, stainless steel, or other hot rolled steel.
3. Bending and Forming
CNC folding and press brake forming shape flat metal into desired geometries. Machines clamp the sheet metal and apply pressure to create curves.
Forming sheet metal further manipulates and shapes the material. The goal is to create a 3D object from a 2D design, from simple parts to custom sheet metal designs. Many complex geometric structures can be created.
Sometimes, forming sheet requires specialized tools for steel sheet metal. Hot rolled steel, aluminum copper, and even plastics can be bent and formed as well.
4. Assembly and Joining
For projects with multiple sheet metal components, various joining processes assemble parts. Welding, like GTAW, fuses parts together.
Hardware like PEM inserts, nuts, studs, and standoffs can be attached using riveting or other hardware insertion techniques. This step is critical when custom sheet metal fabrications have multiple steel sheet components.
5. Finishing
Finishing protects and enhances the final product. It improves corrosion resistance and durability.
Common finishes include polishing and powder coating. The piece is often primed for protection before painting, powder coating, or anodizing.
Choosing between sheet metal finishes and metal finishes in general depends on application and sometimes the base sheet metal materials that were chosen which can also have an affect on material thickness.
Exploring Sheet Metal Fabrication Materials
Different metals offer varied properties. Sheet metal stands out as a highly functional material in many instances.
Carbon steel, aluminum, and copper and its alloys are just some of the available sheet metal materials for your project and ordering online through custom sheet metal fabrication services, or a general custom sheet metal supplier should be possible.
Material | Properties | Common Applications |
---|---|---|
Steel (Carbon, Stainless, Galvanized) | Strong, durable, cost-effective, various finishes | Construction, automotive, industrial machinery |
Aluminum | Lightweight, corrosion-resistant, good conductivity | Aerospace, electronics, packaging |
Copper and its alloys (Brass, Bronze) | Excellent conductivity, corrosion-resistant, malleable | Electrical components, plumbing, decorative items |
Sheet Metal Fabrications: Design Considerations
Effective design is crucial for the functionality, durability, and cost-effectiveness of any sheet metal service. Here’s guidance adapted from a sheet metal fabrication guide:
General Design
Maintain uniform wall thickness across parts (aim for 0.5mm – 10mm). Consider realistic tolerances, as multiple bends can affect tolerance difficulty.
Design for Laser and Waterjet Cutting
When designing, make accommodations for material thickness as well as how each part gets put together in the end. To reduce sharp corners on sheet metal parts created by a laser cutting service consider creating small curves where different segments come together, also making sure there’s appropriate room around those edges after its been cut.
Laser cut sheet metal will separate with cuts but if holes are needed for later use such as hardware insertion of rivets, or standard fasteners during final sheet metal assembly then it’s best practice to space all those holes further apart so the parts structural integrity doesn’t become an issue.
Design for Bending
If using 3D software like CAD, be mindful of the K-factor to minimize tearing when form sheet metal. Use inner radius curves equal to or greater than the material thickness.
Avoid repeating the same curve with different rotations. Incorporating reliefs and ensuring bend heights exceed twice the material thickness can also prevent problems. Consult a K-factor chart or conduct material tests.

FAQs about Sheet Metal Fabrications
What are the three types of metal fabrication?
Three core categories of sheet metal fabrication exist: cutting, forming/bending, and assembly. Cutting shapes the metal using methods like laser or waterjet cutting.
Forming/bending shapes the blank using press brakes or other tools. Assembly joins multiple parts into a finished unit using methods like welding, rivets, and screws with PEM inserts. The fabrication process depends on several factors including sheet thickness as well.
What is sheet metal fabrication?
Sheet metal fabrication involves taking thin metal sheets, cutting, and reforming them into 3D shapes. It is part of the subtractive manufacturing process. Techniques used during the process are laser cutting, bending, and welding.
Lead times will be a few more business days when standard lead times are being met by fabrication services and will also take a bit longer if there are more simple parts to a sheet metal project.
These techniques can be used for various types of production parts. It allows for the fast creation of production or prototype pieces. Its precision and versatility make it suitable for products ranging from electronics enclosures to jewelry.
Is metal fabrication a good career?
A career in sheet metal offers various roles, including fabricator and former. Metal fabrication combines CAD software, machine tools, and hands-on work.
Jobs are in high demand because it involves a subtractive manufacturing process. It’s a career with stability, good income, and the satisfaction of creating everyday products.
How much do metal fabricators charge?
Pricing depends on several factors: chosen material, production time, order volume, and finishing. Obtain quotes from multiple sheet metal fabricators for accurate pricing and availability.
Prices fluctuate with demand, supply, and material availability. Precision sheet metal and the need for precision sheet will often increase costs depending on what is involved and materials including aluminum which is more expensive can have even higher costs associated.
