Perforated sheets for sieve separators are usually produced by punching, using normal Carbon steel and quality steel (S700, durable steel) 500, Creusabro, etc...
Calendered sheets can be supplied for the production of cylinders, for instance to produce rotating screens.
The use of perforated sheets in the sieving process enables improved productivity in many fields of operation: pharmaceutical, chemical, metallurgic, environmental and for special programs of chipping, control sifting (industrial sieves) and solid filtering.
