There are 2 distinct groups for wire cloth usage: inclusion or exclusion. • In inclusion applications, the opening between wires is the primary factor • In exclusion applications, wire type and diameter are the key factors DEFINITIONS Mesh size.The number of holes per inch, measured from center of the wire. Wire Diameter.Diameter of each individual wire, given in inch measurements. Opening size.Measurements of each individual opening in the mesh. Open area percentage.Percentage of total cloth surface that is open space.						MATERIALS 304 Stainless Steel The most common grade of stainless steel (also referred to as "18-8"); offers good corrosion resistance in typical atmospheres. 316 Stainless Steel The second most common grade (after 304) for food and petrochemical applications. Molybdenum content provides additional corrosion resistance.		GRADES Defined by wire gauge and opening size/open area %. As opening size increases, open area % increases. Large Opening—Has the largest-gauge wire and largest opening size. Standard (Market)—Suitable for general purpose screening. Wire diameter is larger than milling grade, with a lower % of open area. Milling—Thinner wire with an even smaller opening size and larger open area %. Bolting—Woven in very smooth and durable stainless steel. Wire diameter is smaller than milling grade, allowing a high % of open area.
