Stainless steel wire mesh Plain weave: this type is most commonly used. East warp wire passes alternately over and under weft wires at right angles, and vice versa. Openings are square and wire sizes are the same in warp and weft. Twill weave: This type is similar to plain, except that weft wire passes alternatively over and under two warp wires (instead of one) in a staggered fashion. Very fine meshes can be woven more readily in twilled weave than in plain. Dutch weave: this type is a filter cloth construction made in the same way as plain weave, except that the weft wires are "driven up" to give a tighter woven cloth with minute openings.
