Stainless Steel Polishing

For over three decades, AAA Metals Company has been an industry leader in stainless steel polishing, with full in-house capabilities to carry out belt sanding, grinding, face, edge, and OD polishing. Our advanced equipment includes a double head machines as well as belt sanders, with ceramic, zirconia, and nylon impregnated grinding belts.

Our polishing operation runs on an infinite control system, with PLC touch screen user interfacing. We produce 180 to 320 grit finishes, with experience producing #3, #4, #6, Scotch-Brite™, and down to 20 Ra designated finishes. We polish sheet, plate, bar, tubing, angle, and channel material forms, with acceptable shapes including flat, square, rectangular, round, “I”, and “T” shapes.

Polishing is available for parts sized up to 24′ in length, up to 12′ in width, 12″ in height, and 12″ in diameter, with weights up to 9,000 lb. We are proud of the ability to handle part widths of 12′, a distinction few business in the New England area can claim. In addition to premium polishing, we provide a full menu of value added services including forming, bending, rolling, drilling, welding, grinding, and other specialty processes. Typical turnaround times for polishing range from hours to weeks, and we handle prototype production to volumes of hundreds of units.
