2BA Finish Stainless Steel Sheet
Product Overview
Industrial-grade cold-rolled stainless steel sheets featuring a bright, reflective, and smooth surface produced via controlled bright annealing and skin-passing. Designed for fabricators and OEMs requiring tight dimensional tolerances, consistent mechanical properties, and a clean aesthetic finish without secondary polishing.
Standard Thickness Range: 0.3 mm to 3.0 mm
Standard Widths: 1000 mm, 1219 mm, 1500 mm (Custom slitting available)
Common Grades: Austenitic (304/304L, 316/316L) and Ferritic (430)
Quality & Compliance: Manufactured under ISO 9001 quality management system; EN 10204 3.1 Traceable MTC provided with every shipment
Reflective Bright Finish: Retains a smooth, mirror-like sheen from the controlled protective-atmosphere annealing process, reducing pre-fabrication surface prep.
Controlled Mechanical Properties: Skin-passed to eliminate stretcher strains and optimize formability for deep drawing and bending.
Consistent Gauge Tolerance: Produced on precision 20-high or 6-high cold-rolling mills, maintaining strict thickness uniformity across the entire coil/sheet.
Edge Integrity: Available in both mill edge and precision slit edge with burr-free finishing for automated processing lines.
Surface Protection: Covered with optional laser-cuttable PVC or polyethylene protective films (up to 100 um) to prevent scratching during handling and fabrication.

Key Characteristics & Typical Use |
|
304 / 304L |
S30400 / 1.4301 & 1.4307 |
Standard austenitic grade; excellent corrosion resistance, formability, and weldability. Used in food processing and architectural panels. |
|
316 / 316L |
S31600 / 1.4401 & 1.4404 |
Molybdenum-alloyed austenitic grade; enhanced resistance to pitting and chemical corrosion. Used in marine, pharmaceutical, and chemical equipment. |
|
430 |
S43000 / 1.4016 |
Ferritic grade; cost-effective with good corrosion resistance in mild environments. Used in household appliances, automotive trim, and interior cladding. |
Food & Beverage Processing Equipment: Tanks, chutes, conveyors, and work surfaces requiring sanitary, easy-to-clean surfaces.
Pharmaceutical & Cleanroom Interiors: Wall panels, ductwork, and equipment housings where particle shedding and contamination must be minimized.
HVAC & Appliance Manufacturing: Heat exchanger components, stove panels, range hoods, and refrigeration linings.
Architectural & Interior Design: Elevator cabins, escalator panels, decorative trim, and column covers.
Automotive Exhaust Systems: Heat shields and muffler components requiring high-temperature oxidation resistance.
Custom Thickness and Dimensions
To minimize material waste and optimize fabrication yields, we supply sheets cut-to-size and coils slit to exact operational requirements.
Custom Lengths
Precision cut-to-length lines ranging from 500 mm to 6000 mm.
Slitting Services
Narrow width slitting down to 20 mm with tight width tolerances (+/- 0.15 mm).
Film Application
Single-side or double-side protective masking (Laser film, fiber laser film, or black/white PVC).
Quality Control and Surface Inspection
Every production batch undergoes strict quality verification before dispatch, backed by certified testing and independent inspection options:
Spectrometric Analysis
Direct-reading spectrometer testing to verify chemical composition against mill heat numbers.
01
Mechanical Testing
Tensile testing, yield strength verification, and Rockwell/Vickers hardness testing per ASTM/EN standards.
02
Dimensional Inspection
Micrometer and laser gauge verification for thickness, width, length, and diagonal squareness.
03
Surface Inspection
Manual and optical inspection under high-intensity lighting to detect pinholes, scratches, oil stains, roller marks, and edge cracks.
04
Third-Party Verification
Support for pre-shipment inspections by authorized agencies (e.g., SGS, TÜV, BV) upon client request.
05
Packaging, Shipping & Trade Terms
Export-standard packaging engineered to withstand multi-modal transit (ocean freight and inland trucking) without edge deformation or moisture damage:
Sheet Packaging: Wooden pallets with waterproof interleave paper, strapped with steel bands, wrapped in moisture-resistant vapor barrier film, and protected with heavy-duty edge protectors.
Coil Packaging: Eye-to-wall or eye-to-sky vertical/horizontal packing on wooden skids, wrapped with waterproof Kraft paper and plastic film.
Container Loading & Payload Limits: Professional load distribution for 20GP containers (safe payload cap managed around 25 metric tons gross to comply with port and highway regulations).
Incoterms Support: Flexible trade terms offered, including FOB, CIF, CFR, and DDP upon project review.
