"Strainer for zinc chrome"
I am a student and currently taking my on the job training (ojt) in a steel corporation. The company I am currently in is doing paints on Galvanized steel but before they put on the paints, they first allow the substrate to pass thru a roller with zinc chrome as pre-coating. However, the substrate sometimes acquire zinc lines and spots which I believe is caused by uneven distribution of the zinc-chrome because there is no stainer to remove big lumps or particles of the zinc-chrome. The engineers say there used to be a strainer but it did not last long because of corrosion caused by the zinc-chrome. The stainer was made of aluminum. What material could we use to make a strainer that could be more resistant to the corrosion brought by the zinc chrome? thank you.Claire Anne A. Bingit

You didn't mention the size of the piping where the strainer was, did you?
Ever considered plastics? For line strainers these are
available most certainly to 2" dia possibly slightly larger, I forget. Very inexpensive.
You can, of course, get CPVC filter strainers with PP mesh.
From anywhere from l to l00 microns ... not cheap.
Please be more specific the next time. THANKS.
