Flattened Expanded Metal (DIN 791 / ASTM F1267) is used for smooth-faced guards, shelves, grilles and filter layers made from expanded metal that is cold-rolled flat after expansion.
Also known as: flattened expanded metal, flattened expanded metal mesh, expanded aluminum mesh, flat expanded metal sheet
Pattern: SWD × LWD after flattening (the diamond lengthens slightly).
Thickness: Flattening reduces thickness by about 10–15 %.
Material: Carbon steel, stainless or expanded aluminum.
Materials
Standard supply is stainless steel 304, stainless steel 316/316L; the material column in the table and the drawing options show the exact grade for each size. Other alloys and finishes can be quoted to your drawing.
Fitting & Care
Frame or band edges, as flattened strands remain sharp.
State the diamond direction on drawings for consistent panels.
Common Mistakes
Expecting the stiffness of raised expanded metal.
Ordering the wrong diamond direction.
When Flattened Expanded Metal Is Not the Right Choice
Not for walkways that need slip resistance — use raised expanded metal or grating.
Flattened Expanded Metal is stocked and supplied to order in rolls, cut sheets and fabricated pieces. Pricing starts from approximately US$15.00 per unit for standard specifications in stainless steel 304; final pricing depends on specification, alloy, quantity and fabrication (MOQ applies).

What is flattened expanded metal?
Expanded metal rolled flat after expansion to give a smooth surface.
Is expanded aluminum available flattened?
Yes, and it is widely used in air filters.
Flattened or raised expanded metal?
Flattened is smooth and thinner; raised is stiffer and gives grip.
What specifications are available for Flattened Expanded Metal?
The table on this page lists 5 standard specifications for Flattened Expanded Metal, from 6x12 to 22x50. Specifications outside the table — custom mesh counts, wire diameters, roll widths and fabricated pieces — can be quoted on request.
