Key takeaways
- Sheet metal fabrication cuts, bends, and joins flat metal sheet into finished parts โ ideal for enclosures, brackets, panels, and chassis.
- Processes: laser cutting, punching, bending (press brake), stamping, welding, and finishing.
- Materials: mild steel, stainless steel, aluminum, galvanized steel, copper, and brass, typically 0.5โ6 mm.
- No minimum order โ rapid sheet metal prototypes in as fast as 3โ7 business days.
- Upload your CAD (STEP/DXF) for a free DFM review and quote.
What is sheet metal fabrication?
Sheet metal fabrication is the process of turning flat metal sheet into finished parts by cutting, forming, and joining. A part starts as a flat blank that is cut to shape (laser, punch, or shear), bent to form flanges and features on a press brake, then welded, riveted, or fastened into an assembly and finished. Because it works from standard sheet stock with reusable tooling, it is fast and cost-effective for enclosures, panels, and structural parts in low to mid volumes. Learn the basics in our sheet metal fabrication guide.
Our sheet metal services
Laser Cutting & Punching
Fast, precise cutting of complex profiles, holes, and cutouts from sheet.
Bending & Forming
Press-brake bending of flanges, hems, and complex forms to tight angles.
Stamping
High-volume stamped parts with custom dies for repeatable features.
Welding & Assembly
TIG/MIG/spot welding, riveting, and hardware insertion into assemblies.
Hemming & Finishing
Hemmed edges plus powder coating, anodizing, and plating.
Sheet Metal Prototyping
Fast, no-MOQ prototypes to validate fit and form before production.
Sheet metal materials
We fabricate the most common sheet metals, typically 0.5โ6 mm thick:
- Mild / cold-rolled steel โ strong and economical for brackets and frames
- Stainless steel (304, 316) โ corrosion resistance for medical, food, and outdoor parts
- Aluminum (5052, 6061) โ lightweight, corrosion-resistant enclosures and panels
- Galvanized steel, copper, and brass โ for plating, conductivity, or appearance

Design for sheet metal (DFM)
Good sheet metal design keeps bends, holes, and flanges within manufacturable limits โ consistent wall thickness, adequate bend radii, and enough edge distance for holes near bends. Read our sheet metal design tips and how to avoid common defects to get right-first-time parts.
