All woven wire mesh used in Impact Test Sieves is manufactured from stainless steel.
Impact woven wire sieves are shown below.
The depth of the sieve is measured from the top of the frame to the surface of the woven wire mesh or perforated plate.
The sieve diameter is the length of the straight line from inside edge to inside edge of the frame, passing through the centre of the sieve. The sieve diameter should be measured at the top of the sieve.
