Raised Expanded Metal Size Chart | Complete Standard & Custom Sizes 2025
ANPING METAL MESH – Professional Metal Mesh Manufacturing Since 2005
When planning walkways, platforms, stair treads, fencing, or industrial grating, having a reliable raised expanded metal size chart is essential to select the correct diamond opening, sheet size, thickness, and weight for your project. As a leading metal mesh manufacturing company with over 20 years of global export experience, we produce raised expanded metal in full standard sizes and fully customized dimensions to meet ASTM, EN, and JIS international standards.
In this comprehensive guide, we provide our complete raised expanded metal size chart, explain key sizing terms (SWD, LWD, strand width, thickness), list standard sheet sizes, compare sizes by application, and show you how to order the perfect size for your project. This page is designed to be your complete reference for raised expanded metal sizing.
What Is Raised Expanded Metal?
Raised expanded metal is the original, unflattened expanded metal product, made by slitting and stretching a solid metal sheet to create a raised, textured diamond surface. It offers superior slip resistance, high strength-to-weight ratio, and natural drainage — making it ideal for walkways, platforms, stair treads, and industrial grating.
Unlike flattened expanded metal, raised expanded metal retains its raised diamond structure, which provides excellent traction in wet, icy, or oily conditions. It is available in galvanized steel, aluminum, and 304/316 stainless steel.
Common applications: walkway grating, stair treads, platform flooring, drainage covers, security screens, machine guards, fencing, and construction grating.
Key Raised Expanded Metal Size Terms (Must-Know)
Before using our raised expanded metal size chart, you need to understand the standard industry terms used to describe dimensions. These terms are universal across global manufacturers:
- SWD (Short Way of Diamond): The shorter diagonal distance of a single diamond opening (mm/inch)
- LWD (Long Way of Diamond): The longer diagonal distance of a single diamond opening (mm/inch)
- Strand Width: The width of the metal strip forming the diamond (mm/inch)
- Strand Thickness: The thickness of the original metal sheet (mm/inch)
- Sheet Size: The total length and width of the expanded metal sheet (ft/m)
- Weight: Weight per square meter or square foot (kg/m², lbs/ft²)
All sizes in our raised expanded metal size chart use these standard terms to ensure accuracy and compatibility with your project designs.
Complete Raised Expanded Metal Size Chart (Standard Sizes)
Below is our official raised expanded metal size chart for galvanized steel (most popular), aluminum, and stainless steel. All sizes are produced in our ISO-certified factory and available for immediate bulk production.
| Model | SWD (mm) | LWD (mm) | Strand Width (mm) | Thickness (mm) | Weight (kg/m²) | Application |
|---|---|---|---|---|---|---|
| RM-01 | 5 | 12 | 1.0 | 1.0 | 1.2 | Filters, Screens, Small Hole Mesh |
| RM-02 | 8 | 16 | 1.5 | 1.5 | 2.1 | Security Screens, Guards |
| RM-03 | 10 | 20 | 2.0 | 2.0 | 3.2 | Fencing, Panels |
| RM-04 | 12 | 25 | 2.5 | 2.5 | 4.3 | Walkways, Platforms |
| RM-05 | 16 | 32 | 3.0 | 3.0 | 5.8 | Stair Treads, Grating |
| RM-06 | 20 | 40 | 3.5 | 3.5 | 7.2 | Industrial Grating |
| RM-07 | 25 | 50 | 4.0 | 4.0 | 9.1 | Heavy-Duty Platforms |
| RM-08 | 32 | 64 | 5.0 | 5.0 | 12.4 | Trench Covers, Heavy Grating |
Note: Custom sizes are available with SWD from 3mm–80mm, thickness from 0.5mm–8.0mm, and any sheet size you require. We can also produce raised expanded metal according to your drawing specifications.
Standard Raised Expanded Metal Sheet Sizes
In addition to diamond opening sizes, sheet size is a critical factor in installation and cost. We offer all standard international sheet sizes and can cut custom sizes to your exact dimensions.
| Standard Sheet Size | Metric Size (mm) | Common Use |
|---|---|---|
| 3×6 ft | 914 × 1829 | Small Projects, Guards |
| 4×8 ft | 1219 × 2438 | Universal Standard Size |
| 4×10 ft | 1219 × 3048 | Walkways, Platforms |
| 5×10 ft | 1524 × 3048 | Industrial Grating |
| 1m × 2m | 1000 × 2000 | Metric Global Standard |
| 1.2m × 2.4m | 1200 × 2400 | Construction, Export |
The 4×8 ft (1.22×2.44m) sheet is the most popular size globally, as it fits standard framing and is easy to transport and install. For large industrial projects, we recommend full 1.5m×3m sheets to reduce installation labor.

Material Thickness & Weight Comparison
Thickness directly affects strength, weight, and price. Use this quick reference to select the right thickness from our raised expanded metal size chart:
| Thickness (mm) | Material Type | Strength Level | Typical Use |
|---|---|---|---|
| 1.0 – 1.5 mm | Galvanized / Aluminum | Light | Screens, Filters, Guards |
| 2.0 – 3.0 mm | Galvanized / Aluminum | Medium | Walkways, Fencing, Stairs |
| 3.5 – 5.0 mm | Galvanized Steel | Heavy | Industrial Grating, Trench Covers |
| 5.0 – 8.0 mm | Galvanized Steel | Extra Heavy | Heavy-Duty Platforms |
Aluminum raised expanded metal is 1/3 the weight of steel, making it ideal for architectural and lightweight applications where corrosion resistance is needed.
