Stainless Steel Perforated Sheet Applications and Specifications
Stainless steel perforated sheets offer unique combinations of functionality and aesthetics, serving applications from industrial filtration to architectural design.
Material Selection
Stainless Steel Grades
| Grade | Corrosion Resistance | Applications |
|---|---|---|
| 304 | Good general purpose | Indoor, general environments |
| 316 | Excellent | Outdoor, coastal, chemical |
| 316L | Excellent | Welding required |
| 430 | Moderate | Indoor decorative only |
Hole Patterns and Configurations
Round Holes (Most Common)
- Staggered 60 degrees: Maximum open area, strongest pattern
- Staggered 45 degrees: Good strength, unique appearance
- Straight: Easier cleaning, directional flow
Standard Round Hole Specifications
| Hole Diameter (mm) | Open Area (%) | Common Applications |
|---|---|---|
| 0.5-1.0 | 10-30 | Fine filtration, insect screens |
| 1.0-3.0 | 20-50 | Air filtration, guards |
| 3.0-8.0 | 30-60 | Ventilation, architecture |
| 8.0-20 | 40-70 | Drainage, sorting |
Industrial Applications
