Twilled weave means Wire Cloth in which
each warp wire and each shute wire passes successively over and under
the two adjacent wires -- in both the warp and shute directions. This
over and under movement is shifted one wire with each pass of the
shuttle. This pattern permits the weaving of heavier wires in varying
meshes.
Materials:SS 302, SS 304, SS 304L, SS 316, SS 316L, SS 321 and SS 430 etc.
Features
Stainless steel twilled weave wire
mesh have the features of wear resistance, heat-resisting,
acid-resisting, alkali resisting, durable structure, and corrosion
resistance.
