This guide includes printable standard size charts, terminology explanations, application matching, and customization options. Whether you need small-hole filtration mesh, heavy-duty industrial grating, or architectural facade panels, our complete sizing reference will help you make accurate purchasing and design decisions.
Key Terminology for Stainless Steel Expanded Metal Sizes
Before reviewing the sizes chart, it is essential to understand the standard terms used to define stainless steel expanded metal dimensions. These terms are universally used in the industry and will help you read the chart accurately and communicate your requirements clearly.
- SWD (Short Way of Diamond): The shorter diagonal measurement of the diamond opening
- LWD (Long Way of Diamond): The longer diagonal measurement of the diamond opening
- Strand Width (W): The width of the metal strip forming the mesh
- Material Thickness (T): Original thickness of the stainless steel sheet
- Sheet Size: Length × width of the finished expanded metal panel
- Flattened Thickness: Thickness after rolling (for flattened expanded metal)
All our size charts use these standard industry measurements to ensure consistency with international specifications (ASTM, EN, and JIS). Accurate understanding of these terms prevents ordering errors and ensures your expanded metal fits your project perfectly.
Standard Stainless Steel Expanded Metal Sizes Chart
Below is our complete official stainless steel expanded metal sizes chart, covering raised (standard) and flattened types, common thicknesses, diamond openings, and strand widths. This chart includes the most popular sizes used in architecture, industry, filtration, and construction worldwide.
| Material Thickness (T) | SWD × LWD (mm) | Strand Width (mm) | Type | Typical Application |
|---|---|---|---|---|
| 0.5mm | 3×6 | 1.0 | Flattened | Fine Filtration, Crafts |
| 0.8mm | 5×10 | 1.2 | Flattened | Vent Covers, Lighting |
| 1.0mm | 8×16 | 1.5 | Both | Decorative Screens |
| 1.2mm | 10×20 | 2.0 | Both | Interior Design |
| 1.5mm | 12×25 | 2.5 | Both | Wall Cladding |
| 2.0mm | 15×30 | 3.0 | Both | Facade Panels |
| 2.5mm | 20×40 | 4.0 | Raised | Security Grilles |
| 3.0mm | 25×50 | 5.0 | Raised | Walkway Grating |
| 4.0mm | 30×60 | 6.0 | Raised | Industrial Platforms |
| 5.0mm | 40×80 | 8.0 | Raised | Heavy-Duty Gratings |
| 6.0mm | 50×100 | 10.0 | Raised | Mining, Construction |
This chart represents our most in-demand stock sizes. All sizes are available in 304 and 316 stainless steel. For projects requiring precision, our small hole expanded metal mesh (3×6mm to 8×16mm) is the first choice for filtration and fine safety applications.
Standard Sheet Sizes for Stainless Steel Expanded Metal
We supply stainless steel expanded metal in fixed standard sheet sizes for cost-effectiveness and easy transportation. These sizes are compatible with global shipping containers and common construction frameworks. Custom cut sizes are also available upon request.
| Standard Sheet Size | Imperial Equivalent | Common Use |
|---|---|---|
| 1000mm × 2000mm | 40" × 79" | General Purpose |
| 1220mm × 2440mm | 48" × 96" | Architectural Panels |
| 1500mm × 3000mm | 59" × 118" | Large Facades |
| Custom Size | Custom | Project-Specific |
Standard sheets minimize waste and reduce costs. For large-scale architectural projects, we offer oversized panels to reduce installation joints. As a professional expanded metal facade manufacturer, we can produce sheet sizes tailored to your building dimensions.
Flattened vs. Raised Expanded Metal Size Differences
One of the most important considerations in the sizes chart is the difference between raised (standard) and flattened expanded metal dimensions. The flattening process changes the physical thickness and slightly affects the opening dimensions, which must be accounted for in design.
- Raised Expanded Metal: Retains original 3D structure, thickness = material thickness
- Flattened Expanded Metal: Rolled flat, thickness is reduced and uniform
- Opening Change: Flattening slightly increases SWD/LWD by 3-5%
- Surface: Flattened is smooth; raised is textured and stronger
Our size charts clearly mark flattened and raised types to avoid design errors. For architectural and decorative applications requiring a smooth surface, flattened sizes are preferred. For structural and load-bearing uses, raised expanded metal sizes provide superior strength.
How to Select the Correct Size from the Chart
Choosing the right size from the stainless steel expanded metal sizes chart depends on your application, load requirements, ventilation needs, and aesthetic goals. Follow this practical guide to match the perfect size to your project.
1. Determine Opening Size (SWD × LWD)
Small openings (3×6 to 10×20mm) provide security, filtration, and privacy. Medium openings (15×30 to 25×50mm) balance ventilation, light, and appearance. Large openings (30×60 to 50×100mm) offer maximum airflow and visibility for facades and platforms.
2. Select Material Thickness
Thin sheets (0.5–1.5mm) are for lightweight decoration and filtration. Medium thickness (2.0–3.0mm) suits most architectural and safety uses. Heavy thickness (4.0–6.0mm) is designed for industrial grating, mining, and high-load applications.
3. Choose Sheet Size
Use standard sheet sizes for small projects and cost efficiency. Order custom sheet sizes for large-scale installations to reduce cutting waste and installation time. Our team can help you optimize sheet sizes for your project.
Custom Sizes Beyond the Standard Chart
While our standard sizes chart covers most applications, we specialize in fully customized stainless steel expanded metal sizes for unique projects. No matter how specific your requirements are, we can manufacture to your exact drawings and specifications.
