What Is No 4 Stainless Steel Finish – And Why It Matters

No 4 Stainless Steel Finish

When working with stainless steel, surface finish is more than just visual appeal — it directly impacts cleanability, corrosion resistance, and how the material performs in its final application. Among the most popular finishes in industrial and architectural settings, the No 4 stainless steel finish stands out for its versatility, durability, and modern aesthetic.

✅ What Is a No 4 Stainless Steel Finish?

The No 4 finish is a brushed, directional surface finish created by polishing stainless steel with abrasives in the 180–400 grit range. The result is a smooth yet non-reflective surface with a uniform grain that enhances both appearance and functionality.

It is often referred to as “No.4 brushed finish” or “4B finish”, and is widely recognized as a standard in industries that value hygiene and aesthetics in equal measure.

✅ Common Applications

At Art Steel Magic Co., Limited, we supply No 4 finished stainless steel coils and sheets to a wide range of industries. This finish is especially well-suited for:

  • Commercial Kitchens
    Easy to clean, resistant to bacterial buildup, and compliant with food-grade hygiene requirements.
  • Elevators and Public Interiors
    The brushed texture helps hide fingerprints and minor scratches, reducing maintenance in high-touch environments.
  • Architectural Facades and Panels
    Designers and contractors choose No 4 for its subtle reflectivity and sleek appearance, making it ideal for both exterior and interior use.

✅ How No 4 Finish Is Produced

In our Foshan-based processing facility, the No 4 finish is achieved through a multi-step polishing process using precision abrasive equipment. Here is a simplified overview:

  1. Surface Cleaning – Coils and sheets are cleaned to remove oils, scale, and contaminants before polishing.
  2. Initial Abrasion – Coarse grit belts remove surface defects and ensure flatness.
  3. Main Polishing – Abrasives in the 180–400 grit range create the uniform brushed grain.
  4. Final Inspection – Every product is visually checked to ensure consistent texture and finish.

Our strict quality control ensures that every stainless steel sheet meets both technical and aesthetic expectations.
