Sheet N4 Finish

Stainless steel sheet with an N4 finish, also known as No. 4 finish or brushed finish, is one of the most popular and widely specified surface treatments available for stainless steel flat products. Characterised by a unidirectional, fine-brushed appearance produced by polishing with progressively finer abrasives, the N4 finish strikes the ideal balance between aesthetic appeal and practicality, offering a modern, clean look that is easy to maintain and resistant to showing fingerprints, scratches, and surface contamination.

The N4 finish is produced by mechanically abrading the surface of the sheet in a single linear direction, creating a consistent, parallel grain pattern. This soft sheen is visually appealing without being as reflective as a mirror or high-polish finish, making it well-suited to environments where glare reduction is important. Available in both Grade 304 and Grade 316 stainless steel, this product can be specified to suit a wide range of applications and environments.

Grade 304 N4 sheet is commonly used for kitchen equipment, splashbacks, benchtops, wall panels, lift interiors, signage, shop fronts, and architectural cladding. Grade 316 N4 sheet with its molybdenum addition is the preferred choice for marine environments, food processing facilities, pharmaceutical production areas, and exterior architectural applications in coastal or industrial zones where superior corrosion resistance is required.

Stainless steel N4 sheet is available in a broad range of thicknesses and standard sheet sizes, enabling specifiers and fabricators to select the precise material for their project. It can be easily cut, folded, welded, and formed without compromising the base material’s properties. The combination of aesthetic refinement, durability, hygienic surface properties, and low maintenance makes N4 finish stainless steel sheet one of the most practical and professional choices available for both functional and decorative applications.
