What are Stainless Steel Bars?
Stainless steel bars are robust, long-lasting metal sections available in various shapes including round, square, hexagonal, and flat. These bars are crucial in numerous sectors due to their high strength, notable corrosion resistance, and excellent formability. They are manufactured using several processes to achieve precise dimensions and desired mechanical properties.
