Test sieves with round apertures are used for a variety of agricultural products including corn (4.50 / 4.75 mm), sorghum (1.8 mm), oilseeds (starting from 0.5 mm), soybeans, different cereals and numerous others.

Blau-Metall test sieves with perforated plates are made exclusively of stainless steel components and employ precision aperture technology to meet the tolerances of ISO 3310-2. Additional sieve sizes – not included in typical ISO standards – are manufactured to the same stringent tolerance requirements and also come with detailed inspection documents in accordance with EN 10 204.
