Primary construction consists of mostly stainless steel.  Some mild steels may be used in frames, flanges, or end plates.  All product flow through areas are constructed with stainless steel and magnet materials are enclosed in stainless steel.
 
Seams between two metal parts are stitch welded.  There may be some small gaps between two joined parts.  All stainless steel areas are either polished with a scotchbrite type polishing pad or sand blasted using a glass media.  Mild steel components are painted.
