Our Stainless Steel Sheet Metal Parts Bending Parts Welding Brushed Sheet Metal Fabrication Service specializes in high-performance components for demanding environments where corrosion resistance, hygiene, and structural integrity are critical. Utilizing 304/316 stainless steel alloys, we combine precision bending, robust welding, and specialized surface finishing to produce parts that meet FDA, medical, and industrial standards. From simple brackets to complex assemblies, our integrated processes ensure consistency across production runs and compliance with strict quality requirements.
We use 304 stainless steel (18-8 chromium-nickel) for general corrosion resistance (salt spray test ≥1,000 hours) and 316 stainless steel (with 2-3% molybdenum) for enhanced resistance to chemicals, saltwater, and high temperatures—ideal for marine and medical Applications .
Our CNC press brakes achieve ±0.2 mm linear tolerance and ±0.5° angular accuracy on bends, with minimum bend radii of 1× material thickness. This precision supports complex geometries like box enclosures, U-channels, and multi-axis brackets .
TIG welding delivers clean, porosity-free joints with weld strength ≥200 MPa and minimal distortion, while MIG welding is used for high-volume structural components. All welds undergo visual inspection and pressure testing for critical Applications .
Custom finishes include brushed surfaces (Ra 0.8–1.6 μm) for reduced glare and improved grip, mirror polishing (Ra ≤0.02 μm) for aesthetics, and passivation (per ASTM A967) to enhance corrosion resistance by removing free iron particles .
All parts meet ISO 9001:2015 quality standards, with medical-grade components compliant with FDA 21 CFR Part 175 and USP Class VI biocompatibility requirements. Custom certifications (CE, RoHS) are available upon request .
Medical: Surgical instrument trays, MRI machine enclosures, and hospital bed frames.
Food Processing: Conveyor system components, mixing tank lids, and stainless steel work surfaces.
Architecture: Indoor/outdoor handrails, decorative panels, and signage frames.
Marine: Boat hardware, offshore platform components, and corrosion-resistant fasteners.
Can you achieve tight tolerances for aerospace components?
Yes, our precision press brakes and CMM inspection enable ±0.15 mm positional accuracy for critical parts like aerospace brackets and sensor mounts .
What’s the lead time for welded assemblies?
Small batches (1–50 parts) are delivered in 5–10 days, while large production runs (500+ parts) require 15–20 days, including finishing and quality checks.
Is passivation included in the standard service?
Passivation is standard for medical, food, and marine Applications, using nitric acid or citric acid treatments to form a protective oxide layer. It is optional for non-critical industrial parts.
Do you offer assembly services for complete systems?
Yes, we provide full assembly including bolt/nut fastening, riveting, gasket installation, and functional testing to deliver turnkey subassemblies ready for integration.
How do brushed finishes compare to polished ones in durability?
Brushed finishes (Ra 0.8–1.6 μm) are more resistant to fingerprints and scratches than mirror polished surfaces, making them ideal for high-touch Applications like medical equipment and kitchen hardware.
