Raised Diamond MeshMutual Metal Catalog

Standard expanded metal

Standard expanded metal is a raised diamond mesh produced by slitting and stretching solid sheet without material waste. The strands remain raised and angled off the sheet plane, providing an inherently rigid, slip-resistant surface engineered for demanding industrial environments.

Manufacturing Characteristics

Zero-waste expansion: Continuous slit-and-stretch fabrication produces zero scrap metal compared to conventional punching.

One-piece integrity: Knitted structural bonds have no welds or joints to loosen under vibration or heavy impact.

Natural anti-slip: Raised diamond knuckles bite into footwear and wheel surfaces in wet, oily, or icy settings.

Dimensional specifications

Standard expanded metal is specified by diamond axis dimensions and strand geometry to match precise load capacities and open area requirements.

Orientation & Bond Geometry

Short Way of Diamond (SWD) is measured center-to-center across diamond knuckles. The knuckle joints form continuous trusses for structural stiffness across wide unsupported spans.

SWD Range:0.25 in – 3.00 in
Strand Width:0.031 in – 0.500 in

Primary industrial applications

Specified across industrial plants, manufacturing facilities, architectural envelopes, and transport infrastructures.

Walkway treads & catwalks

Provides self-draining, high-traction footing for industrial plants, stairs, and overhead gantries.

Security fencing & enclosures

Rigid one-piece diamond barrier that resists cutting, climbing, and perimeter breach.

Machine guards & partitions

Maintains clear optical visibility and airflow while shielding operators from moving mechanical parts.

Ventilation louvers & grilles

Allows unrestricted cooling airflow and acoustic relief while blocking large debris and pests.
