Practical experience with coastal environments, surface treatment, plate thickness, and flatness requirements.

Stainless steel for curtain walls commonly uses 304 and 316L; 316L is preferred in coastal or highly polluted environments.

Key points:
- Surface: Brushed (No.4) and mirror (8K) finishes are the main types. For outdoor use, brushed finish is recommended as scratches are less noticeable.
- Plate thickness: Calculated based on design wind pressure and support spacing, commonly 1.5-3.0mm.
- Flatness: Curtain walls have high appearance requirements; flatness tolerance limits and protective film must be specified.
- Processing: After bending and welding, pickling and passivation are required to prevent weld corrosion.

Acceptance focus: Color difference, scratches, flatness, and weld treatment.
