Expanded Metal Specifications & Dimensions
Compare reference patterns used in the USA, UK, Germany, France and Australia. Confirm material, finished dimensions and availability for your order.
For accurate quotation and production, expanded metal mesh should be measured by SWD (Short Way of Diamond), LWD (Long Way of Diamond), strand width, sheet thickness, sheet width, and sheet length. These expanded metal mesh specifications directly affect opening size, weight, strength, ventilation rate, and application performance.

Pitch ≠ clear opening. Diagram labels: TL = short way, TB = long way, b = strand width, d = metal thickness, B = sheet width and L = sheet length. Specify whether the short and long dimensions on your drawing are bond-center pitches (SWD / LWD) or clear openings (SWO / LWO).
- LWD × SWD
- Long × short way of the diamond pitch, measured between corresponding bond centers.
- Strand width & thickness
- Strand width is w; base metal thickness is t. Raised overall thickness T is a separate dimension.
- SWO / LWO
- The short and long dimensions of the clear opening between strands; these are smaller than the corresponding diamond pitches.
- Open area & sheet size
- Open area is the percentage occupied by openings. Sheet size is the overall width and length; specify diamond orientation separately.

What Is Stainless Steel Expanded Metal?
Stainless steel expanded metal is made by slitting and stretching stainless steel sheet into a continuous diamond opening pattern. It provides strength, airflow, visibility, stable openings, and corrosion resistance without welded intersections.
YueChu Metal supplies custom stainless steel expanded metal sheets for filtration, food processing equipment, chemical systems, marine environments, machine guards, walkways, screens, and architectural panels.
- Available in 201, 304, 316, and 316L stainless steel grades.
- Strong corrosion resistance for demanding industrial environments.
- Custom openings, thicknesses, sheet sizes, and surface conditions.
- Suitable for filtration, food, chemical, marine, and architectural use.
304 vs. 316 Stainless Steel Expanded Metal
Grade 304 is widely used for general industrial, food, filtration, and architectural applications. Grade 316 contains molybdenum and is commonly selected for marine, chemical, and higher-corrosion environments.
Applications of Stainless Steel Expanded Metal
Typical uses include filtration support, food processing equipment, chemical processing, marine systems, machine guards, walkways in corrosive environments, screens, and architectural panels.
Expanded Metal Manufacturing & Customization
A slit-and-stretched sheet, configured around your project.
Slitting and stretching turn solid sheet into connected mesh. Raised mesh retains angled strands; rolling creates a smoother, flattened profile. Cutting, forming and finishing follow your agreed specification.
Custom options to discuss
- Material and grade
- SWD / LWD and clear openings

Buyer questions
Stainless Steel Expanded Metal FAQ
What stainless steel grades are available?
We supply stainless steel expanded metal in 201, 304, 316, and 316L grades. Grade selection depends on corrosion exposure, hygiene requirements, operating environment, and fabrication needs.
What is the difference between 304 and 316 stainless steel expanded metal?
Grade 304 is a common choice for general industrial, food, filtration, and architectural uses. Grade 316 contains molybdenum and offers better resistance in marine, chloride, and chemical environments.
Which grade is better for marine or chemical use?
Grade 316 or 316L is generally preferred for marine, chloride, and many chemical environments. Final selection should consider the specific chemical, concentration, temperature, and service conditions.
Can you produce custom stainless steel expanded metal sheets?
Yes. We support custom grade, opening size, strand width, thickness, sheet dimensions, raised or flattened profile, surface condition, and export packing based on drawings or samples.
What information is needed for a quotation?
Please send the stainless grade, thickness, SWD, LWD, strand width, sheet size, surface finish, quantity, application, and destination port for an accurate quotation.
