| Plain Square: | The most common weave, with the same diameter
warp and shute wires woven in a simple over and under patttern. It produces
screens with the same mesh count in both directions. |
| Twill Square: | Each shute wire typically passes over two warp wires
and under two, producing square openings. Twill weave can be made from larger
diameter wires than would be possible in plain square weave to obtain greater
strength, density, or corrosion resistance. |
| Plain Dutch: | Woven in an over and under pattern, but warp wires are
heavier -- larger in diameter -- than shute wires which are driven very
close to create a high density wire mesh with much lower flow rates and
much higher particle retention than plain square weaves. |
| Other weaves: | Variations of the basic styles are also available
and offer a variety of benefits: twill dutch, reverse dutch, stranded
and rectangular weaves are among these types. |
| Conventional Double Crimp: | Most common type. Used where the opening is relatively small in comparison
to the wire diameter |
| Lock Crimp: | Used only in coarse specifications to maintain the accuracy of weave throughout
screen life where the opening is large with respect to wire diameter |
| Inter Crimp: | Used in coarse weaves of lighter guage wire to provide greater stability,
tightness of weave and maximum rigidity. Very common in mesh openings larger
than 1/2". |
| Flat Top: | Usually starts at 5/8" opening and larger. Provides long abrasive resistant
life since there are no projections on top to wear. Offers least resistance
to flow. Also very popular in certain architectural and structural applications
where a smooth surface on one side is desirable. |
| Very strong, dense wire cloth with openings from about 250 microns down to only 5 microns (1 micron = .0000394"). |

Usually woven in a Dutch Style Weave, wires are driven very close to create
a wire cloth that does not have straight-through openings as in a square weave,
but instead creates a torturous path through which very fine filtration can be
achieved. Shute wires are usually of a smaller diameter than the warp wires
to allow for a tighter dense weave. Filter cloth is identified by its "Absolute Filter Rating" which is a measure of the largest hard spherical particle that can pass through the mesh. Typical uses for filter cloth are ultra-fine filtration and sound suppression, but it may also be used in a variety of structural decorative or electronic applications. |
