Architectural-Grade Stainless Steel Sheets: 8K/12K Mirror Polished
Product Overview
Our stainless steel sheets are engineered for high-end architectural and decorative applications, offering unmatched reflectivity and durability. Designed with 8K/12K mirror-polished finishes, these sheets are ideal for luxury interiors, exterior cladding, and artistic installations. Available in Home Depot-compatible sizes (4ft x 8ft standard) and customizable thicknesses, they combine aesthetic brilliance with industrial-grade performance. Certified to ASTM A240 and SGS standards, our sheet metal stainless steel resists corrosion, scratches, and fingerprints while maintaining a flawless reflective surface.

Key Properties & Performance
Tensile and Bending Strength
The stainless steel sheets achieve tensile strengths of 520–580 MPa, ensuring structural integrity under heavy loads. For bending applications, the cold-rolled 304/316 alloys withstand **≤90° angles without cracking**, making them suitable for curved architectural elements like column covers and ceiling panels.
Weight Calculation

Rust Prevention & Causes
While stainless steel sheets are corrosion-resistant, rust may occur due to:
- Chloride Exposure: Coastal environments or de-icing salts degrade the passive chromium oxide layer.
- Mechanical Abrasion: Scratches from improper cleaning tools expose the base metal to oxidation.
- Low Oxygen Environments: Stagnant water in crevices inhibits self-repair of the protective layer.
- Chemical Contamination: Contact with sulfuric acid or chlorine-based cleaners accelerates corrosion.
Manufacturing & Identification
Production Process
- Cold Rolling: Raw 304/316 coils are precision-rolled to achieve 0.5–15mm thickness with ±0.03mm tolerance.
- Solution Annealing: Heat-treated at 1050–1100°C to eliminate internal stresses and enhance corrosion resistance.
- Mirror Polishing: Multi-stage buffing with diamond abrasives to achieve 8K/12K finishes (12K = zero visible flaws).
- PVD Coating: Optional gold/black coatings applied via physical vapor deposition for decorative versatility.
Identification Marking
Each sheet is laser-marked with:
- Grade (304/316)
- Thickness (e.g., 3mm)
- Batch number
- Compliance logos (ASTM, SGS).
Applications
- Luxury Interiors: Elevator panels, decorative wall cladding.
- Exterior Architecture: Stainless steel sheets Home Depot-compatible façade systems.
- Art Installations: Sculptures and reflective art pieces.
- Retail Spaces: High-gloss countertops and display units.
