Market grade cloth is made of one size wire for each size closed mesh.MESH - Number of openings per lineal inch, measured from center of wire tocenter of wire.MICRON - 1/1000 millimeter, 0.00003937 inch. The unit of measure for particle retention of lter media.OIL TEMPERED WIRE - High carbon steel wire that is heat resistant to produce good strength and abrasion resistance.OPENING - Dimension between parallel adjacent wires. RECTANGULAR MESH - Wire cloth with different warp and ll wire mesh counts, which results in rectangular openings. The most common have a higher warp mesh than lter mesh. Advantages are increased open area, and reduced cost. SELVAGE - The nished edges of wire cloth running the length of the roll, which are produced by the weaving operation.SPACE CLOTH - Wire cloth specied by the opening size, rather than by the mesh count.SQUARE MESH - Mesh with equal spacing of warp and shute to give squareopenings.WARP WIRE - Foundation wires running parallel to the length of the cloth.WEAVES - Pattern in which wires areinterwoven.WIRE DIAMETER OR GAUGE - Diameter of wire used in weaving cloth.2 MESH WIRE CLOTH(count from center to center of wires)1/2 INCH OPENING WIRE CLOTH(clear space between wires)PLAIN WEAVEWires are crimped in a zig-zag fashion, with wires intersecting at every available crimp or pocket.INTERCRIMPWires are crimped in a zig-zag fashion, with intersections at every 3rd, 5th or 7th, etc., crimp or pocket.LOCK CRIMPDistinct crimp or pocket at wireintersection, with straight connectingsections of wire.FLAT TOPTop surface of wires all lie in same plane.Irregular crimped surface on underside.
