SWD (Short Way Diamond): The dimension measuring the distance from the center of one bond to the center of the bond on the opposite side, measured in the shorter direction of the expanded metal sheet.
LWD (Long Way Diamond): The dimension measuring the distance from the center of one bond to the center of the bond on the opposite side, measured in the longer direction of the expanded metal sheet.
Strand Thickness: The thickness of the metal sheet before expansion. It's also referred to as gauge or thickness.
Strand Width: The width of the uncut metal sheet before expansion.
Opening Size: The size of the diamond-shaped or other openings created by the expanding process.
SWO (Short Way Opening): The dimension measuring the distance from one side of the opening to the other in the shorter direction of the expanded metal sheet.
LWO (Long Way Opening): The dimension measuring the distance from one side of the opening to the other in the longer direction of the expanded metal sheet.
Mesh: A term sometimes used to describe the pattern created by the expanded metal, particularly when the openings are uniform in size.
Raised: When the bonds in expanded metal are elevated above the original plane of the metal sheet.
Flattened: When the bonds in expanded metal are flattened so that the expanded metal has a smoother, flatter surface.

Grating: Expanded metal that is designed for use as a walking surface, catwalk, or for drainage.
Decorative: Expanded metal used for aesthetic purposes, often with intricate patterns.
Perforated Metal: A different type of metal sheet with regularly spaced holes, not to be confused with expanded metal.
Weld Mesh
Wire Diameter: The thickness of the individual wires used to create the mesh. It's usually specified in gauge or millimeters.
Mesh Size: The measurement of the distance between the centers of adjacent wires or the spacing of the mesh openings. It can be specified in inches or millimeters and may be described as the number of openings per unit length.
Aperture: The opening or hole formed by the intersection of the horizontal and vertical wires in the mesh. It's often described in terms of its dimensions (e.g., 1-inch square aperture).
Wire Gauge: A standardized measurement of wire thickness. The gauge number is inversely proportional to the wire diameter; smaller gauge numbers represent thicker wires.
Panel Size: The dimensions of a single sheet or panel of welded mesh, typically specified in length and width.
Roll Length: For welded mesh that is sold in rolls, this term refers to the length of the roll. Roll width may also be specified.
Mesh Pattern: The arrangement of the horizontal and vertical wires in the mesh, which determines the overall pattern of openings. Common patterns include square, rectangular, and diamond.
Welding Process: The method used to join the wire strands at their intersections. Common methods include resistance spot welding and electric fusion welding.
Galvanized Weld Mesh: Welded mesh that has been coated with a layer of zinc to provide corrosion resistance.
Stainless Steel Weld Mesh: Welded mesh made from stainless steel wire, which is highly resistant to corrosion and staining.
Weld Strength: The strength of the welds that hold the wires together at their intersections. It's an important factor in determining the mesh's overall strength.
Finish: The surface treatment or appearance of the welded mesh, which can be plain, galvanized, PVC coated, or powder coated, among other options.
Mesh Opening Direction: Indicates the orientation of the mesh pattern, whether it's square or diamond, and which dimension (length or width) corresponds to the openings.
Tensile Strength: The maximum load that the welded mesh can withstand when subjected to tension or pulling forces.
Roll Width: For welded mesh sold in rolls, this term refers to the width of the roll. Roll length may also be specified.
PVC Coated Weld Mesh: Welded mesh that has been coated with a layer of PVC (polyvinyl chloride) for added protection and aesthetic appeal.
Powder Coated Weld Mesh: Welded mesh that has been coated with a layer of powdered paint that is cured to form a durable and attractive finish.

Wire Diameter: The thickness of the individual wires used to create the woven mesh. It is typically specified in gauge or millimeters.
Mesh Size: The measurement of the distance between the centers of adjacent wires or the spacing of the openings in the woven mesh. It can be specified in inches or millimeters and may be described as the number of openings per unit length.
Aperture: The opening or hole formed by the intersection of the horizontal and vertical wires in the woven mesh. It's often described in terms of its dimensions (e.g., 1/2-inch square aperture).
Wire Gauge: A standardized measurement of wire thickness. The gauge number is inversely proportional to the wire diameter; smaller gauge numbers represent thicker wires.
Mesh Pattern: The arrangement of the horizontal and vertical wires in the woven mesh, which determines the overall pattern of openings. Common patterns include plain weave, twill weave, and Dutch weave.
Weave Type: The specific method used to interlace or connect the horizontal and vertical wires in the woven mesh. Common weave types include plain weave (most common), twill weave, and Dutch weave (dense and used for fine filtration).
Plain Weave: In this common weave pattern, each wire passes alternately over and under the adjacent wires in both the warp (vertical) and weft (horizontal) directions.
Dutch Weave: This weave uses two different wire diameters, with the thicker wire in the warp direction and the finer wire in the weft direction. It results in a dense mesh with precise filtration capabilities.
Selvage Edge: The finished edge of a woven wire mesh sheet where the wires are bound or finished to prevent unraveling.
Mesh Count: The number of openings or apertures per linear inch or unit length, often used to describe the fineness or coarseness of the woven mesh.
Roll Length: The length of a roll of woven wire mesh, typically specified in meters or feet. Roll width may also be specified.
Roll Width: The width of a roll of woven wire mesh, typically specified in meters or feet. Roll length may also be specified.
Weave: The most common type of weave in woven wire mesh is characterized by a simple over-under pattern where each wire passes over one and under the next wire.
Chain Link
Mesh: Mesh refers to the pattern of interwoven metal wires that make up the body of the chain link fence or net. It consists of diamond-shaped openings created by the crisscrossing wires.
Gauge: Gauge is a measure of the thickness or diameter of the wire used to make the chain link.
Mesh Size: Mesh size refers to the distance between the centers of adjacent diamonds in the chain link pattern. It is often specified in inches, such as 2 inches by 2 inches, and can vary depending on the desired level of security or containment.
Nylon Netting
Mesh Size: Mesh size refers to the distance between two adjacent knots or intersections in the netting. It is often measured in inches or millimeters and is a crucial factor in determining the net's functionality and purpose. Smaller mesh sizes are used for fine filtration or catching small objects, while larger mesh sizes are used for applications like sports or cargo containment.
Gauge: Gauge refers to the thickness or diameter of the nylon twine or filament used to make the netting. It is typically measured in denier (a unit of linear mass density) or as a diameter in inches or millimeters. A higher gauge indicates a thicker and stronger net.
Knot Type: The way the nylon filaments are secured at intersections can vary. Common knot types in nylon netting include square knot, diamond knot, and selvedge (a reinforced edge) for added durability.
Stretchability: Nylon netting can be designed to have varying degrees of stretchability. Some applications require a net with high elasticity to accommodate stretching and movement, while others may require minimal stretch for stability.
Selvage: Selvage refers to the reinforced edges of a net. These edges are typically thicker and more robust than the rest of the net and help prevent fraying or damage along the perimeter.
Twine Thickness: This term refers to the thickness of the individual nylon filaments used to construct the netting. Thicker twine is generally stronger but may result in a heavier net.
Breaking Strength: The breaking strength of nylon netting is the maximum force or load the net can withstand before breaking. It is measured in pounds or kilograms and is an important factor in determining the net's suitability for specific applications.
UV Resistance: Some nylon netting is treated to be UV-resistant, which helps it withstand prolonged exposure to sunlight without deteriorating or becoming brittle. This is especially important for outdoor applications.
Knotless Netting: In contrast to traditional knotted netting, knotless netting is constructed without knots at the intersections. This results in a smoother surface and reduced drag, making it suitable for sports like soccer or lacrosse.
Square Mesh: Square mesh is another common pattern where the intersections create square-shaped openings. It is often used in fishing nets and some sports applications.
Barrier Netting: Barrier netting is designed to provide safety or containment in various settings, such as sports fields, construction sites, and industrial areas.
Cargo Netting: Cargo netting is used for securing and transporting cargo, especially in trucks, trailers, and shipping containers.
Fishing Netting: Nylon netting is widely used in fishing for catching various types of aquatic species. Different mesh sizes and twine thicknesses are used for different fishing purposes.
