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 best 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.

What to Send for Expanded Metal

• Material, thickness and strand width.
• SWD, LWD and sheet size.
• Raised or flattened style if known.
• Finish, color or surface treatment requirement.
• Application, quantity, packing and destination.
