The reference image also portrays a standard expanded metal variant, with highlighted zones demonstrating the elevated, anti-skid edge feature.
Bond: The junction where two neighboring strands converge. 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): 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: An important 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. 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. Metal grating is expressed in weight per square foot terms.
