Most popular type. Used where the opening is relatively small in comparison to the wire diameter (3 to 1, or less).

Used only in coarse specifications to maintain the accuracy of weave throughout screen life where the opening is large with respect to wire diameter (3 to 1, or greater)

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".

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.
