D: Wire diameter in mm.

W: Mesh opening. Distance in mm. between two adjacent wires.

Besides the material of the wire used and type of cloth, some other features stated on the table:

S%:  Working surface. Approximate percentage of the total surface of the openings of a mesh.

Kg/m2: Approximate weight in kg of a m2 of an iron/steel woven wire cloth. (See conversion factor table for other materials).

Núm: Mesh number. It is the quantity of mesh openings in a given length unit. The woven wire cloth is formally defined by parameters W and D, so this information is merely a guidance to give a simple description of the mesh. But it is included herein since it is still widely used in two different versions, calculated as follows (in mm.):

S = (100w2 ) / ((w+d)²)

Mesh 25,4 = 25,4 / (w+d)

Num. 27,77 = 27,77 / (w+d)
