alternately to make a plain cloth. Their manufacturing wire
diameter ranges between 1.50 mm and 5 mm, with square meshes within
a wide range of possibilities. The cloth can have more or less

of wire corrugations, their depth and distance between them; these
are factors to be borne in mind according to use needs.
