F. CARL SCHRÖTER - mesh table

Wire mesh DIN 4189 (mesh table)

Screen bottoms made of steel, stainless steel and non-ferrous metal wire, with the exception of spring wire. Wire mesh with square meshes.

Technical list

w Mesh width in mm. The mesh width is the clearance between two adjacent warp or weft wires, measured in the projected plane. The ISO has decided that all mesh widths above 1 mm are to be given in millimetre and all those less than 1 mm in micron (1 mm = 100 micron).

d Wire diameter in mm in accordance with DIN 4186. Measured in the finished wire mesh in the projected woven plane.

F₀ Open screen area or degree of screen opening.
kg Woven weight in kg per m². Conversion factors for materials other than steel (100): stainless steel (101), copper (114), monel metal (112.5), brass (110), phosphor bronze (112.5), nickel (112.5).

No.: cm number of meshes per lineal cm.

Mesh number of meshes per lineal inch, 25.4 mm (rounded numbers).

To calculate the mesh use the following table or our calculation sheet.
