Expanded Metal Mesh: SWD, LWD, Strand and Sheet Size Basics
Expanded metal buyers can avoid unclear quotations by confirming opening direction, strand data, sheet size, material and finish before price comparison.
Expanded metal mesh is used for guards, platforms, ventilation, partitions, walkways, screens and decorative panels. The diamond opening makes it visually recognizable, but quotation requires more than a photo.
SWD and LWD Describe the Diamond Opening
SWD means short way of diamond, and LWD means long way of diamond. These dimensions help define the opening pattern and direction. If a buyer sends a drawing, it should make clear which direction is width, length and installation direction.
Thickness and Strand Width Affect Strength
Material thickness and strand width influence weight, rigidity, open area and cost. Two sheets with similar-looking openings can behave differently if thickness or strand width changes. This is why photos should be supported by measurement whenever possible.
Raised or Flattened Style Should Be Confirmed
Expanded metal may be raised or flattened depending on application and finish requirement. Raised mesh has a textured surface, while flattened mesh is passed through rolls for a flatter profile. The suitable choice depends on installation, appearance and handling needs.
Finish and Packing Matter for Sheet Products
Finish may include galvanized, powder coated, painted, anodized or buyer-required treatment depending on material and application. Sheets may need pallet packing, protective layers, labels or size grouping for warehouse handling.

Expanded Metal FAQ
What do SWD and LWD mean?
SWD means short way of diamond, and LWD means long way of diamond. They describe the two directions of the expanded metal opening.
What if I only have a photo?
A photo can start the review, but a drawing, sample measurement or previous supplier spec helps confirm opening, strand and sheet details.
Why should raised or flattened style be confirmed?
Raised and flattened expanded metal can differ in surface feel, appearance and handling, so the style should be included before comparing quotations.
