Perforated Stainless Steel Sieves SS 304 and SS 316 for Sand Grading, Grain Sorting, Chemical Powder Screening and Testing

Perforated plate sieves are manufactured by punching metal sheets, then cutting, forming and framing into standardized sieve assemblies. Perforated plate sieves are made mainly from round hole perforated metal sheets, also rectangular and square hole perforated sheets..

Materials: Stainless Steel 304, ss 305, ss 316, also mild steel

Uses: Perforated metal sieves are widely used in laboratories, construction materials testing, aggregate and sand analysis.

Perforated Plate Sieves Hole Shapes We Supply:
Hole shapes: Round hole standard. Other hole sizes such as Square and rectangular also available upon request.

Round hole perforated plate sieves (ISO, ASTM, and BS standards): most popular, standard test sieves.
We also square hole and slotted perforated sieves:
Square hole perforated sieves: For accurate sizing of angular particles or granules;
Slotted (rectangular) hole perforated sieves: For elongated particles such as fibers, chips, or pellets or drainage applications.

Why Perforated Plate Sieves Instead of Woven Wire Mesh Sieves?
Test sieves made of perforated sheets/plates enable improved productivity in many fields of operations: pharmaceutical, chemical, metallurgic, environmental and for special programs of chipping, control sifting (industrial sieves) and solid filtering.

Why Round Hole Perforated Plate Sieves?
Round hole perforated metal sieves are the most commonly used screening materials with uniform circular openings, uniform particle passage, accurate sizing and easy cleaning.

Four technical factors for choosing the right round hole perforated plate sieves:
First, choose the right metal material: Carbon steel sieves or different grades of stainless steel. It depends on the work conditions and corrosion resistance property demand.
Secondly, Hole diameters: We supply perforated sheets with small, medium and large holes to meet various sizing requests.
Thirdly, Hole patterns: Stright line or staggered pattern ( 60 degree, 90 degree). The most popular hole arrangement is the 60 degree angle pattern, which combines a high rigidity and a decent proportion between open and full areas . The 90° pattern is equally popular, above all for aesthetic needs whereas the 45° pattern is now almost disused.
Fourthly, the pitch distance or interaxis. This means the minimum distance between the centers of two adjacent holes. Whether you need standard pitch or custom pitch.
