The 304 stainless steel sheet with #4 brushed finish delivers a perfect balance of utility and aesthetics. This surface treatment involves mechanically polishing the metal with fine abrasives to produce a consistent, linear grain that enhances both appearance and functionality.

Unlike mirror-polished or bright-annealed finishes, the #4 brushed style offers a muted, satin-like surface with low reflectivity and excellent resistance to fingerprints, making it ideal for high-contact or visible applications like kitchen panels, elevator doors, and decorative wall coverings.

Engineered from grade 304 stainless steel, this product retains excellent corrosion resistance and formability, making it suitable for indoor and outdoor architectural environments. Whether it's for commercial kitchens or modern interiors, the #4 brushed finish adds a refined, professional look without being too flashy.
