Insect cloth
Plain weave mesh wire screen cloth, typically 18 x 16 or 18 x 14 mesh, available in aluminum, bronze, fiberglass, galvanized or stainless steel wire. Also referred to as "fly-screen".
Market Grade
A group of industrial wire cloth specifications suitable for general purpose screening applications, made of high strength square mesh cloth, available in several types of material. The wire diameters are moderately larger than "mill grade" , with a lower percentage of open area.
Medium mesh
Wire cloth having a mesh count of 30 x 30 to 90 x 90 inclusive.
Mesh No.
This generally denotes the number of apertures in a length of 25.4mm (1"). While it is considered an obsolete designation, it is used extensively.
Mesh
Mesh designates the number of openings and fractional parts of an opening, per lineal inch. Mesh is determined by counting the number of openings from the center of any wire to the center of a parallel wire, one inch in distance.
When the point one inch distant from the center of a wire falls between wires within an opening, the mesh count is expressed as a fraction.
Micron
One micron is equivalent to 0.001mm or 0.00003937 inches. The micron is the unit of measure in the metric system. It is frequently used when referring to the aperture size or particle-retention of filter cloth.
Micron retention
Micron retention is defined as the diameter of the largest round particles which can pass through a filter.
Micronic grades
Finer mesh range of Dutch Weave cloth in meshes giving retentions of 50 microns or finer.
Mill Grade
Group of industrial wire cloth specifications with lighter wire diameters than "market grade". Standard wire diameters of this grade produce a medium percentage of open area.
Mud Screen
A wire cloth screen panel fitted with hooks for tensioning installed on shale shakers.
Plain Weave
Woven wire cloth in which each warp and each weft wire passes over one and under the next adjacent wire in both directions.
Plain Dutch Weave
Dutch weave with each warp and shoot wire passing alternately over and under each successive wire.
Reverse Plain Dutch Weave
The arrangement of the warp and shute wire is reversed as compared to Plain Dutch Weave, providing a higher mesh count in the warp direction rather than the weft (shute) direction..
Rice Wire Cloth
Used for polishing rice, wire mesh made of hard-drawn wire and generally available in 12 x 14 mesh using 0.035" / 0.041" diameter wire.
