Stainless Steel Square Bars
Cold Finished and Annealed Stainless Steel Square Bars in Stock
Action Stainless supplies stainless steel square bar in a wide range of sizes to support machining, framing, and structural applications. This bar type is valued for its strength, dimensional stability, and surface quality across both industrial and architectural environments.
We stock cold finished and annealed square bars in
303, 304, 316, and
416 grades. These bars are typically supplied in
12′ lengths
and are ideal for shafts, brackets, and structural supports. Custom cut-to-length and fast turnaround options are available to meet both short-run and high-volume project needs.
T416 square bar
is typically available within 2 to 3 days ARO for expedited delivery.
Finishes & Processing Services
Stainless square bars are typically cold finished to provide a smooth surface and consistent dimensions. Annealing is performed to relieve stress, control hardness, and reduce tool wear during machining.
In-house processing services include saw cutting, bar turning, grinding, and chamfering. Material can be supplied in full bars or cut-to-length based on your production needs.
