ПРОГРЕСС
Product Overview
Our Stainless Steel Strip (also known as stainless steel coil, stainless steel band, or stainless steel foil) is manufactured from premium stainless steel through hot rolling, cold rolling, отжиг, and pickling processes. With excellent corrosion resistance, высокая прочность, precise thickness tolerance, and various surface finishes, stainless strips are widely used in automotive, Электроника, кухонная утварь, строительство, Медицинское оборудование, and general manufacturing. We supply a comprehensive range of stainless steel strips in 304, 304л, 316, 316л, 321, 410, 420, 430, и 201 grades, with custom widths, thicknesses, and surface finishes available.
