Deciphering Expanded Metal Terminology

Navigating the world of expanded metal sheets requires familiarity with specific jargon. These terms are pivotal for grasping the nuances of expanded metal dimensions and the broader scope of related products. Moreover, the reference image portrays a standard expanded metal variant, with highlighted zones demonstrating the elevated, anti-skid edge feature.

Bond: The junction where two neighboring strands converge. Furthermore, it’s important to note that a bond’s width is always double that of the strand.

Strand: Refers to the individual metal strip that delineates the boundary of an opening.

Strand Width: Represents the quantity of metal advanced during the expansion process.

Strand Thickness: Specifies the depth of the original metal sheet from which the expanded version is derived.

Opening / Aperture Size: While most commonly diamond-shaped, the open space framed by the strands and bonds can differ based on distinct die-cutting methods.

SWO or SWA (Short Way of Opening/Aperture): This measures the distance across the sheet, paralleling the shorter side of the diamond, and only factors in the opening’s size.

LWO or LWA (Long Way of Opening/Aperture): Conversely, this gauges the distance parallel to the longer diamond side, considering solely the expanse of the opening.

Mesh: Indicated in inches, it’s the average distance from one bond’s center to the center of its neighboring bond, taken across the SWA.

Percent of Open Area: A crucial metric for professionals, this quantifies how much elements like light or air can traverse the expanded metal.

Pitch: Denotes the span from a specific point on one diamond to the identical point on its neighboring diamond. Furthermore, this measure might vary across the sheet in some ornamental patterns.

Style: For expanded metal, the style is denoted by the gauge number, indicating the metal’s thickness before expansion. Moreover, metal grating is expressed in weight per square foot terms.
