The No.4 stainless steel finish is one of the most widely used surface finishes for stainless steel today. It is produced through a mechanical brushing process that creates fine, uniform lines running in a single direction, giving the material a modern and professional appearance.
This finish is also known as No.4 brushed stainless steel or short hairline stainless steel, and is commonly applied to 304 No.4 stainless steel, 430 No.4 stainless steel, and other stainless steel grades used in construction, interior design, and industrial equipment.

Compared with other stainless steel finishes such as BA and 8K Mirror Finish, No.4 offers several outstanding advantages:
Fine, uniform brushed texture with an attractive appearance.
Helps minimize the visibility of fingerprints and minor scratches.
Easy to clean and maintain.
Low reflectivity, reducing glare.
Suitable for both industrial applications and decorative purposes.
Thanks to these characteristics, No.4 remains one of the most commonly used stainless steel finishes in the market.
The fine brushed texture creates a sophisticated, modern, and professional look. This is why decorative No.4 stainless steel is widely used in commercial buildings, hotels, shopping centers, and office complexes.
When applied to stainless steel grades such as 304 and 430, the No.4 finish maintains excellent corrosion resistance, oxidation resistance, and mechanical strength.
Compared to 8K mirror-finish stainless steel, No.4 surfaces show fewer fingerprints and smudges, making cleaning easier and helping maintain a clean appearance over time.
