Stainless Steel Flat Bars
Versatile Sheared and True Flat Bars in 304 and 316
Action Stainless supplies stainless steel flat bars in sheared, edge conditioned, and true bar profiles for structural, architectural, and general fabrication use. Flat bars are widely used across marine, food service, and manufacturing applications for their clean finish, strength, and consistent width.
We stock
304 and
316 stainless in both sheared and true flat bar options. Sizes range from
1/8″ to 3/4″ thick and up to
10″ wide. Most bars are available in
12′ lengths, with select items offered in
20′ lengths up to 1/2″ thick. Polished finishes are also available.
Finishes & Processing Services
Flat bars are typically supplied as sheared and edge conditioned with smooth edges and uniform width. These bars can also be polished on all four sides to brush, #3, #4, or #6 finishes for decorative or sanitary use. We also offer true flat bar produced by extrusion, providing tighter tolerances and sharp 90-degree corners. In-house processing includes saw cutting, finishing, and polishing to meet your exact job specifications.
