Is the mesh "glued" or soldered?
We have and will always solder the mesh during fabrication. Over time, solder has superior holding and will not become brittle, crack, or fall out.


What is the wall thickness of your sieves?
Over the years other manufacturers have "thinned out the material to save money. We have never used thinner inferior material in our sieves. This "in our opinion" cheapens the product substantially.


Is the Mesh High Quality?
The most important part of the sieve is the mesh. We have a relationship with the world leader in wire cloth that dates back to the on start of Dual Mfg.

Certified Sieves – We can perform a detailed analysis of opening and wire diameter, in both inches & millimeters.

Recalibration of Sieves - Taking in your used sieves and recertifying so that you are sure your sieves in use still conform to A.S.T.M. specifications.

Matched Sieves - Manufacturing your sieves out of the same width and roll of mesh, then, we take those groups of mesh and run them thru a series of certifications which are presented to the purchaser upon receipt of order.

Simply return any used sieve to Dual (stating on the shipping label that they are to be recycled) and we will dispose of the product in a proper order.

“I would just like to tell you that I am very impressed with your product. Recently I purchased a set of 3" diameter sieves to test our production of coffee grounds. Previous sieves I have had (I tried 3 different manufacturers) have caused problems with inconsistency.
