Stainless Steel Sheet Metal Parts – Precision Fabricated Components by A1 Metallics
A1 Metallics is a trusted manufacturer and exporter of stainless steel sheet metal parts for industries across the USA, Canada, and Europe. Our stainless steel fabricated components are produced using advanced laser cutting, CNC punching, press braking, deep drawing, and welding processes to deliver components with superior dimensional accuracy, corrosion resistance, and aesthetic finish.
From simple stainless steel brackets and enclosures to complex assemblies, A1 Metallics handles the full spectrum of stainless steel sheet metal fabrication—all backed by ISO 9001:2015 certification and rigorous quality controls.
Stainless Steel Sheet Metal Stamped Parts
Our progressive die stamping and compound die stamping capabilities produce high-volume stainless steel stamped parts including stainless steel clips, brackets, washers, springs, and shims. Stamped stainless steel parts offer excellent repeatability, tight tolerances (±0.05mm), and cost efficiency for mass production. We stamp grades SS 304, SS 316, SS 430, and duplex grades.
Stainless Steel Laser Cut Parts
Using fiber laser cutting technology with power up to 6kW, we cut stainless steel sheets from 0.5mm to 25mm thickness with precision edges, minimal heat-affected zones, and no burrs. Stainless steel laser cut parts include plates, flanges, panels, covers, brackets, and custom profiles. DXF/DWG files are accepted for direct-to-cut processing.
Stainless Steel Press Brake Bent Parts
CNC press brake bending of stainless steel sheet into channels, angles, U-profiles, enclosures, and custom profiles. Our press brakes handle sheets up to 3200mm in length with ±0.1° angular accuracy. Bent stainless steel parts are widely used in food processing equipment, pharmaceutical machinery, marine hardware, and architectural panels.
Stainless Steel Deep Drawn Parts
Deep drawing of stainless steel produces seamless cups, shells, caps, containers, and housings with smooth walls and excellent strength. We deep draw SS 304 and SS 316 into components used in kitchen equipment, instrumentation housings, automotive sensors, and medical devices. Wall thickness uniformity is maintained within ±5%.
Stainless Steel Sheet Metal Enclosures and Boxes
Custom stainless steel enclosures, junction boxes, control panels, and instrument housings fabricated to your exact drawings. We offer MIG welding, TIG welding, spot welding, and hardware insertion (PEM nuts, standoffs) as part of the assembly. Enclosures can be supplied with IP65 or IP67 gasket arrangements per IEC 60529.
Stainless Steel Grades – Sheet Metal Fabrication
The following table lists common stainless steel grades used for sheet metal parts with international equivalents:

| SS 430 | S43000 | 1.4016 | 430S15 | SUS 430 | 10Cr17 | Ferritic, magnetic, decorative panels |
| SS 201 | S20100 | 1.4372 | — | SUS 201 | 12Cr17Mn6Ni5N | Budget alternative to 304, moderate corrosion |
| Duplex 2205 | S32205 | 1.4462 | — | SUS329J3L | — | High strength + corrosion, offshore & chemical |

Frequently Asked Questions – Stainless Steel Sheet Metal Parts
Q1: What stainless steel grades do you work with for sheet metal parts?
We regularly fabricate SS 304, SS 304L, SS 316, SS 316L, SS 430, SS 201, and duplex grades such as 2205 and 2507. Exotic grades like SS 310 and SS 317L are available on request.
Q2: What is the maximum sheet thickness you can process?
We process stainless steel sheets from 0.3mm (foil-grade stamping) up to 25mm for laser cutting. Press brake bending is available up to 15mm thick, and deep drawing typically up to 4mm thick.
Q3: Do you provide surface finishing for stainless steel sheet metal parts?
Yes. Available finishes include mill finish (2B), bright annealed (BA), #4 directional brushed, #8 mirror polish, electropolishing, bead blasting, and passivation per ASTM A967 or AMS 2700.
Q4: Can you produce stainless steel sheet metal parts to my 3D model or drawing?
Absolutely. We accept STEP, IGES, DXF, DWG, PDF, and other standard CAD formats. Our engineering team will review your drawing, suggest DFM improvements if needed, and provide a quote within 24–48 hours.
Q5: Are your stainless steel sheet metal parts FDA / food-grade compliant?
Yes. SS 304 and SS 316 parts produced for food and pharmaceutical applications comply with FDA 21 CFR standards and EU Regulation (EC) No 1935/2004 for food contact materials. Electropolished surfaces meet 3-A Sanitary Standards.
Q6: What is the lead time for custom stainless steel sheet metal parts?
Lead times are typically 3–4 weeks for custom parts requiring new tooling. For repeat orders or laser-cut-only parts, 2–3 weeks is standard. Prototypes (5–20 pieces) can often be completed in 1–2 weeks.
