Produced from high-quality stainless steel and finished to different levels (No. 4, No. 8, mirror, etc.), these bars satisfy visual and hygiene needs across different industries. Being produced in round, square, and flat shapes, Louis Metals provides polished bars customized to suit the needs of clients. For architectural buildings or sanitary fittings, our polished stainless steel bars blend attractiveness, strength, and functionality, all backed by prompt delivery and professional customer care.
Stainless Steel Polished Bars are generally manufactured using 304, 316, or 202 grades, with 18–20% chromium and 8–10% nickel. Polishing makes the surface smoother and less rough, enhancing corrosion resistance and appearance. The bars retain tensile strength of up to 750 MPa and possess superior formability, weldability, and toughness. The finish enhances hygiene and facilitates easier cleaning, which is crucial for food-grade and pharmaceutical applications. Louis Metals guarantees high-precision polishing for uniform appearance and improved protection in aggressive or high-contact applications.
