Product Overview
Our Stainless Steel Flat Bar (also known as stainless steel flat strip or rectangular bar) is manufactured from premium stainless steel billets through hot rolling, cold drawing, or precision grinding processes. With excellent corrosion resistance, alta resistenza, and aesthetic appeal, stainless flat bars are widely used in construction, hardware, kitchen equipment, automotive trim, and general fabrication. We supply a comprehensive range of stainless steel flat bars in 304, 304l, 316, 316l, 321, 410, 420, E 430 grades, with custom sizes and surface finishes available.
