Stainless Steel Square Wire Mesh is classified into two types according to weaving patterns:

Stainless steel square wire mesh plain woven
Stainless steel square wire mesh twill woven

Stainless Steel Wire Mesh Plain weave is the most commonly used weave. Each warp wire crosses alternately above and below each weft wire. Warp and weft wires generally have the same diameter.

Twill Weave Stainless Steel Wire Mesh is made by each weft wire passing alternately over two, and then under two successive warp wires and each warp wire passing alternately over two and under two successive weft wires. It is possible to be used to allow a heavier than standard wire diameter.
Stainless Steel Square Wire Mesh Varieties according to materials:
Stainless steel square wire mesh type 304
Stainless steel square wire mesh type 304L
Stainless steel square wire mesh type 316
Stainless steel square wire mesh type 316L

Type 304 is often referred to as "18-8" ( 18% chromium, 8% Nickel ) with the basic stainless alloy mostly commonly, utilized for wire cloth weaving. It withstands outdoor exposure without rusting and resists oxidation at an elevated temperature up to 1400 Degrees Fahrenheit.

Type 304 L is very similar to T-304, the difference being the reduced carbon content for better weaving and secondary welding characteristics.

Type 316 Stabilized by the addition of 2% molydbenum, T-316 is an "18-8" alloy. It has better resistance to pitting corrosion than the other chromium-nickel stainless steels where brines, sulphur-bearing water or halogen salts, such as chlorides are present. A valuable property of T-316 is high creep strength at elevated temperatures. Other mechanical properties and fabricating characteristics are similar to T-304.

Type 316 L is very similar to T-316, the difference being the reduced carbon content for wire cloth weaving and secondary welding characteristics.
