Glossary
Common Terms in the Stainless Steel Wire Mesh Industry
To help customers better understand product specifications and technical parameters, we have prepared a glossary of common terms in the stainless steel wire mesh industry. Whether you are purchasing wire mesh products for the first time or selecting products for an industrial project, these terms can help you communicate more accurately with suppliers.
Mesh
Mesh refers to the number of openings per inch. For example, 20 mesh means there are 20 openings within one inch. The higher the mesh count, the smaller the openings usually are. The lower the mesh count, the larger the openings usually are.
Wire Diameter
Wire diameter refers to the diameter of the metal wire used for woven or welded wire mesh. A thicker wire diameter provides higher product strength, but reduces the open area. Example: 10 si = 0.1 mm.
Aperture / Opening Size
Aperture refers to the opening between adjacent metal wires. The aperture directly affects filtration accuracy, screening performance, and material passing capacity.
Open Area
Open area is the ratio of the open-hole area to the total mesh surface area. A higher open area provides better air permeability, light transmission, and fluid passing capacity.
Micron
Micron is a commonly used unit for filtration accuracy. 1 micron equals 0.001 mm. In precision filtration, customers often use microns to describe filtration requirements.
Filtration Accuracy
Filtration accuracy refers to the particle size range that the wire mesh can retain. It is related to aperture size, weaving method, wire diameter, and mesh surface structure.
Plain Weave
Plain weave is a structure formed by warp and weft wires crossing over and under each other alternately. It is the most common type of stainless steel woven mesh.
Twill Weave
Twill weave is a diagonal weave structure formed by warp and weft wires crossing according to a specific pattern. It is suitable for products with higher mesh counts or thicker wire diameters.
Dutch Weave
Dutch weave mesh is usually woven with thicker warp wires and finer weft wires. It has a dense structure and high filtration accuracy, and is commonly used for pressure filtration and precision filtration.
Welded Wire Mesh
Welded wire mesh is made by welding longitudinal and transverse wires at each crossing point. It has a firm structure and stable dimensions, making it suitable for protection, fencing, support, and engineering applications.
Crimped Wire Mesh
Crimped wire mesh is woven from pre-crimped metal wires. It has high structural strength and is commonly used for mining screening, mechanical protection, and decoration.
Stainless Steel 304
304 is one of the most commonly used stainless steel grades. It has good corrosion resistance, processability, and overall performance, making it suitable for general industrial environments.
Stainless Steel 316
316 stainless steel contains molybdenum, providing better corrosion resistance than 304. It is especially suitable for humid, salt spray, marine, and chemical environments.
Stainless Steel 316L
316L is a low-carbon version of 316 stainless steel. It has better welding performance and resistance to intergranular corrosion, and is commonly used in food, pharmaceutical, chemical, and filter component applications.
Tensile Strength
Tensile strength refers to the ability of metal wire to withstand tensile force. It is very important for protection, support, and high-strength screening applications.
Tolerance
Tolerance refers to the allowable deviation between the actual product size and the designed size. Common tolerances for wire mesh products include length, width, aperture size, wire diameter, and processing dimension tolerances.
Edge Treatment
Edge treatment refers to processes such as edge wrapping, welding, folding, or framing of wire mesh edges to improve safety, structural strength, and installation convenience.
Passivation
Passivation is a surface treatment process that enhances the corrosion resistance of stainless steel surfaces. It is commonly used for products requiring higher surface cleanliness and corrosion resistance.
Polishing
Polishing is used to improve the surface finish of stainless steel, making the product more attractive and easier to clean. It is commonly used for food equipment, decorative mesh, and some filter components.
Mesh Roll
A mesh roll is stainless steel wire mesh supplied in roll form. It is suitable for customers who need to cut the mesh themselves or use it in continuous production.
Mesh Sheet
A mesh sheet is a product cut to fixed dimensions. It is suitable for installation, protection, filtration, and further processing.
Filter Disc
A filter disc is a filter component made by punching or cutting wire mesh into a round shape. It is commonly used in filters, valves, pipelines, and equipment interfaces.
Filter Cylinder
A filter cylinder is a cylindrical filter component made by rolling, welding, or edge-framing wire mesh. It is commonly used for liquid, gas, and particle filtration.
MOQ
MOQ stands for Minimum Order Quantity. It refers to the minimum quantity required for an order. Different materials, specifications, and processing methods may have different MOQs.
