The primary duty of Standard (Raised) Expanded Metal is walkways, guards, filter supports and screens made from expanded metal mesh — sheet slit and stretched into diamond openings with no welds or joints, so it cannot unravel. Below: the sectors that specify it in volume, the checklist used to select the right mesh and alloy for the application, handling notes, and the known limits of the type.
Typical Applications for Standard (Raised) Expanded Metal
Where Standard (Raised) Expanded Metal is specified and bought:
- Industrial access: expanded steel walkways, platforms and stair treads.
- Machine & window guards: rigid, see-through expanded metal guards.
- Filtration: support cores and grease filter layers.
- Construction: plaster reinforcement and partitions.
How to Specify Standard (Raised) Expanded Metal for Your Application
- Pattern: SWD × LWD (short and long way of diamond), strand width and thickness.
- Raised or flattened: Raised gives grip and stiffness; flattened gives a smooth face.
- Material: Carbon, galvanized, stainless steel or aluminum.
- Standard: Quote DIN 791 / ASTM F1267 and the size designation from the table on the product page, plus any value you changed in the technical drawing.
Handling & Installation Practice
- Span the long way of the diamond across supports for maximum strength.
- Band or frame cut edges, which are sharp.
Common Selection Mistakes with Standard (Raised) Expanded Metal
- Loading the short way of the diamond.
- Using raised mesh where a flat surface is needed.
Where Standard (Raised) Expanded Metal Is Not the Right Choice
Not a precision filter medium — the diamond opening is not controlled to filtration tolerances.
