- Descrizione
304 hairline stainless steel (also known as brushed stainless steel or HL finish) è un surface-treated 304 lamiera di acciaio inossidabile featuring fine, continuous linear textures. This finish combines the corrosion resistance of 304 acciaio inossidabile with an elegant, aspetto moderno, making it widely used in architettura, decorazione, and industrial design.
The hairline finish not only enhances aesthetics but also improves surface durability and scratch resistance compared with mirror or plain finishes.
What is Hairline Finish (HL)?
Attaccatura dei capelli (HL) is a surface processing method created by mechanical brushing or abrasive belt polishing:
- Produces uniform, straight grain lines
- Reduces surface reflectivity (matte finish)
- Improves resistance to fingerprints and minor scratches
- Provides a clean and modern metallic look
