Start with what needs
to arrive.
You can buy custom sheet metal parts from an online manufacturer, a manufacturing network, or a local fabrication shop. The right choice starts with the finished part.
A flat mounting plate may need only cutting and deburring. An enclosure may also need bends, installed fasteners, coating, and a drawing that identifies the surfaces that must look good. A welded frame brings another set of requirements. Calling all three “sheet metal” does not make them the same purchasing decision.
Write down the material and thickness, quantity, finished geometry, critical dimensions, surface requirements, and the date the parts must be in your hands. Then look for a supplier whose process fits that definition.
The useful comparison is the cost of a finished, usable part.
This guide covers several places to start. Our view is straightforward: choose the supplier that can explain how your particular part will be made, checked, and delivered.
From your CAD file
to our shop.
Xeon NC connects online ordering with sheet metal fabrication in Nampa, Idaho.
Our sheet metal fabrication service combines fiber laser cutting and CNC press brake forming for brackets, panels, enclosures, and other custom components. Depending on the material and geometry, your job can also include tapping, countersinking, installed hardware, deburring, powder coating, or Type II anodizing.
For supported parts, start with a CAD upload. Select your material, thickness, quantity, and available processes, then review the quote and any design feedback. Use our material catalog and design guidelines to make those choices against the stock and processes we actually offer.
If the job involves a weldment, assembly, unusual stock, a critical tolerance, or a requirement the online workflow does not capture, use a custom quote. Share the drawing and intended use so our team can review the scope before production. A special requirement belongs in the agreed job definition.
Put the actual design
in front of the process.
Upload your CAD file for standard work, or send the complete requirements for a custom review.

to source parts.
Several services let you begin with a digital file. Each has its own material catalog, design rules, available operations, and quoting process. These are starting points for your evaluation, not a ranking.
SendCutSend
SendCutSend offers online custom sheet cutting and secondary operations including bending, tapping, hardware insertion, and finishing. It also accepts STEP files alongside 2D formats. Its current service and material listings are the place to confirm which options apply to your stock and design.
Protolabs
Protolabs provides sheet metal fabrication with digital quoting and design feedback. Its offering includes cutting, forming, hardware, and fabricated assemblies, with secondary operations such as welding and finishing. Check its sheet metal service against the complete scope of your component or assembly.
Xometry
Xometry sources sheet metal fabrication through a network of domestic and overseas suppliers. Its sheet metal quoting service offers material, finish, and fabrication options. When evaluating a network, ask how production location, inspection requirements, communication, and repeat orders will be handled for your job.
Provider descriptions checked against their official websites on September 18, 2026. Confirm current capabilities, pricing, and delivery for the actual part you intend to order.
Keep local expertise
in the picture.
Some jobs begin with a broken part on a workbench, a measurement at a job site, or a fabrication problem that is still being defined.
A local shop may be a good fit when you need to discuss a physical sample, coordinate an installation, or work through a repair in person. A specialist may be the right starting point for unusual forming, particular welding requirements, or an assembly that depends on dedicated fixtures.
Ask what the shop performs itself, what it sends out, and who is responsible for the final result. Establish the drawing revision, finish expectations, inspection scope, and delivery plan in writing. A productive conversation still needs a clear record.
Location and ordering method are separate decisions. An online manufacturer can offer engineering review, and a local fabricator can work entirely from CAD. Evaluate the actual process behind the front door.
Quote the same part.
All the way through.
Send each supplier the same revision, quantity, material, drawing, and delivery destination. Otherwise, two prices may describe two different jobs.

| Item | Confirm in each quote | Why it matters |
|---|---|---|
| Material | Alloy, grade or temper, actual thickness, and any required documentation. | Similar material names can describe different stock. |
| Operations | Cutting, bends, threads, countersinks, hardware, welding, and finish. | A blank and a completed component have different costs. |
| Acceptance | Critical dimensions, cosmetic faces, inspection scope, and agreed tolerances. | Everyone needs the same definition of an acceptable part. |
| Schedule | Production time, secondary operations, ship date, and transit. | The date a part ships is different from the date it arrives. |
| Delivered cost | Setup, processing, packaging, shipping, and applicable fees. | Unit price alone does not describe the full order. |
For example, compare a powder-coated bracket with installed nuts against that same completed bracket. If one quote covers only the cut and bent part, add the remaining work and handling before deciding which route costs less.
Freight can also change the decision for large or heavy parts. At Xeon NC, review our shipping policy and provide delivery requirements with the order. Compare the complete delivered scope, especially when a larger quantity changes how the shipment is packed.
Give the shop a file.
Give it the requirements.
CAD describes geometry. A complete order also describes the material, operations, and conditions that make the result useful. Before requesting quotes, prepare these five things:
- The correct geometry. Use a clean, full-scale DXF for a flat profile or a STEP model for a formed part, as supported by the supplier. For Xeon, see our STEP versus DXF guide.
- A drawing where it matters. Identify critical dimensions, threads, countersinks, hardware, finish requirements, and cosmetic faces. Make sure the drawing agrees with the model.
- A specific material. State the grade, thickness, and any required temper or surface condition. Confirm the selected stock exists in the supplier’s catalog.
- The order definition. Include part numbers, revision, quantities, delivery destination, and the date the parts are needed.
- The exceptions. Flag special inspection, documentation, packaging, or assembly requirements early so the supplier can review and accept them.
If you are moving a formed part between suppliers, let the receiving shop confirm the flat pattern against its tooling and process. A developed blank prepared for one setup should not be assumed to produce the same finished dimensions on another.
The first part
should teach you something.
When the design is new, an initial quantity gives you a chance to check the physical result before scaling.
Check fit with mating components, fastener access, bend orientation, clearances, and the finish on visible surfaces. Evaluate the assembly in the condition it will actually be used. A part that matches its drawing can still reveal a design assumption that needs attention.
Record any change in the CAD and drawing revision, then make sure the next order references the released files. Keep the material, finish, hardware, and inspection requirements with that revision so a repeat order does not depend on someone remembering a conversation.
A useful supplier relationship makes the next order easier to define. Clear requirements, documented revisions, and direct feedback reduce uncertainty as a design moves into production.
Before you order.
Where can I order custom sheet metal parts?
You can order through a direct manufacturer such as Xeon NC, another online fabrication service, a manufacturing network, or a local shop. Match the supplier’s capabilities to your material, geometry, required operations, inspection needs, and delivery schedule.
What file should I send to Xeon NC?
For flat cut parts, start with a clean, full-scale DXF. For formed sheet metal, use a STEP model of the finished part. Include a matching drawing when you need to communicate critical dimensions, threads, hardware, finishes, or other requirements beyond the geometry.
Can Xeon NC help if I do not have a finished CAD file?
Use the custom quote request to share your drawing, sketch, photos, or part requirements. The Xeon team can review what is needed and discuss the next step. A complete manufacturing definition must be agreed before production.
How do I find the lowest-cost option?
Compare quotes for the same revision, material, quantity, operations, acceptance requirements, and destination. Include finishing, hardware, packaging, shipping, and any work you would still need to complete. The lowest unit price may not be the lowest cost for a usable part.
Should I order a prototype before a production run?
For a new or changed design, an initial quantity can help verify fit, assembly, finish, and function before a larger order. Record what you learn in the released CAD and drawing revision so the production order reflects the validated design.
