If you're looking for expanded metal stainless steel sheets, here's a detailed rundown to help you choose the right one and understand its advantages:
What Is a Stainless Steel Expanded Metal Sheet?
It’s a sheet of stainless steel that's been cut and stretched to form a mesh with diamond or other shaped openings. The process creates a strong, rigid mesh that is ideal for both structural and decorative uses.
Why Use Stainless Steel?
Compared to regular steel or aluminum, stainless steel adds several benefits:
Corrosion Resistance (excellent for outdoor or wet environments)
High Strength-to-Weight Ratio
Aesthetic Appeal (clean, modern, metallic look)
Long-lasting Durability
Low Maintenance
Key Specs to Look For
When selecting a stainless steel expanded metal sheet, check:
| Property | Description |
| Material Grade | 304 (most common), 316 (marine-grade, more corrosion resistant) |
| Sheet Thickness | Measured in gauge (e.g., 16 GA, 18 GA) or millimeters |
| Opening Size | Length & width of the diamond-shaped holes |
| Strand Width | The width of the metal between the openings |
| Open Area (%) | How much of the sheet is open vs. solid metal |
| Sheet Size | Common sizes: 4' x 8', 3' x 6', custom sizes available |
Typical Applications
Marine Environments (316 stainless)
Architectural Facades and Screens
Wall Cladding or Sunshades
Security Panels or Partitions
Anti-slip Walkways, Grates, Ramps
Industrial Platforms, Filters, and Cages
Finishes Available
Mill finish (as-is, slightly dull gray)
Polished (for decorative/architectural use)
Pickled & passivated (for extra corrosion protection)
