Stainless steel Square Bar
Stainless Steel Square, is the more economical stainless square bar ideal for all applications where greater strength and superior corrosion resistance is required. Stainless Square has a durable dull, mill finish that is widely used for all types of fabrication projects that are exposed to the elements - chemical, acidic, fresh water, and salt water environments.
Our supply of stainless steel square bar products come in both the cold drawn and hot rolled condition. Most of our square bar products 3″ and under is cold drawn. Cold drawn bar is shinier in appearance and has a tolerance that is similar to the hot-rolled material, which is usually slightly over-sized. Most of our square bar is supplied in lengths can be cut to size for orders.
