Description

Characteristics:

Here are some key characteristics of a No.4 finish:

1. Matte Appearance: The most noticeable feature of a No. 4 finish is its matte or satin-like appearance. Unlike mirror finishes that are highly reflective, the No. 4 finish has a subdued sheen.
2. Short Polishing Lines: The surface of Stainless Steel with a No. 4 finish exhibits short, fine polishing lines that are uniform and parallel. These lines are typically created using abrasive belts or brushes during the polishing process.
3. Directional Grain: Similar to other brushed finishes, the polishing lines of a No. 4 finish run in one direction, usually aligned with the direction of the metal’s grain. This creates a directional grain pattern on the surface.
4. Smooth Texture: Despite the presence of polishing lines, the surface of Stainless Steel with a No. 4 finish is generally smooth to the touch. The lines do not protrude significantly from the surface, providing a comfortable tactile experience.
5. Subdued Aesthetic: The No. 4 finish imparts a subdued and understated aesthetic to Stainless Steel surfaces. It’s less flashy than mirror finishes but still offers a clean and contemporary appearance.
6. Resistance to Fingerprints: One practical advantage of the No. 4 finish is its ability to conceal fingerprints, smudges, and minor surface imperfections. This makes it suitable for applications where maintaining a clean appearance is important.
7. Versatility: The No. 4 finish is versatile and can be applied to various Stainless Steel grades, thicknesses, and forms, including Sheets, Coils, Plates and fabricated components.
