Common Test Sieve – Woven Mesh, Perforated Test Sieve, or Grid Sieve

A stainless steel common test sieve with cross steel rod under mesh center.

Walcoom provides you all kinds of test sieves for sieving grain, soil, flour or coffee powder.

Common test sieves can be divided into three types: woven mesh test sieve, perforated test sieve and grid sieve.

Woven mesh test sieve is used for precise classification in research laboratory and metallurgy or construction industries with the precise opening. Perforated test sieve has two shapes of openings: square and round. Grid sieve is made of frame and bar, and it is used for flakiness testing of aggregates.

In summary, these test sieves can be used in many place, such as: research laboratory, garden, metallurgy industry, construction industry and so on.
