Compare EP Food Contact Surfaces under 200X Magnification

Apache routinely conducts tests for customers and
in-house studies on the benefits of electropolished surfaces on food contact

Highlighted above, is a study that compares
high-end finishes under 200X

  1. 304 Stainless Steel Bead Blast Finish with
    readings from 35 – 45 RA
  2. 304 Stainless Steel 2B + Electropolished Finish
    with reading from 5 – 6 RA
  3. 304 Stainless Steel 2B Finish (12-gauge material)
    with reading from 15 – 17 RA
  4. 304
    Stainless Steel 2B Finish (10-gauge material) with reading from 20 – 30

It shows the RA (Roughness average) reading in
four finish examples of 304 stainless steel. In the study, the electropolished finish is
more than six times smoother that the bead blasted finish.

What makes this study significant is that food
processors can leverage electropolished surfaces to increase food safety performance.  Our
customer’s who choose electropolished food contact surfaces tell us that food safety is
significantly enhanced, and sanitation efficiencies are realized in time savings and water
