Black Hairline Stainless Steel Sheets
Black hairline stainless steel is designed to deliver both premium aesthetics and practical performance. Black is a neutral tone, yet it carries a strong sense of power while simultaneously evoking luxury and mystery. For this reason, it has long been regarded as a timeless choice, unaffected by shifting color trends.
Black hairline stainless steel significantly reduces the visibility of fingerprints, dust, and fine scratches, helping maintain a refined appearance over time even in high-traffic environments. It also effectively minimizes maintenance and cleaning demands.
In particular, the combination of a deep black tone and a refined hairline texture further enhances the material’s inherent solidity and its bold, weighty presence. In spaces dominated by large glass panels or lightweight finishing materials, black hairline stainless steel serves as a visual focal axis, bringing stability, a sense of trust, and a clearer definition of spatial boundaries.
Black hairline stainless steel leaves a strong impression in any space through its restrained elegance and powerful, substantial presence.

Sapphire’s Proprietary Technology
Stable color regardless of lighting conditions
A deep black appearance that feels intrinsic to the material
Minimal visual change even after short-term contact with cement residue
Color Stainless Steel
Sapphire
The color of black hairline stainless steel is achieved through advanced PVD coating technology in a high-vacuum environment. In this process, Titanium or Chromium is heated and vaporized, then combined with specialized gases, allowing the vaporized material to condense and deposit directly onto the stainless steel surface to form a thin, durable, and uniform coating layer. The detailed color specifications are as follows:
-
CIE Lab: L*48 / a*0 / b*2 (±2)
-
Pantone: 424 C Approx.
-
HEX: #7A7A74 Approx.
-
CMYK: 0 / 0 / 5 / 52 Approx.
Pantone, HEX and CMYK values are approximate references converted from measured CIE Lab values. Actual appearance may vary depending on lighting, viewing angle, surface reflection and surrounding environment.
Color
Hairline finish stainless steel has a uniformly brushed texture with fine, parallel lines running longitudinally. This distinctive grain effectively conceals minor scratches and fingerprints, maintaining its sleek appearance over time.

Project References
Black hairline stainless steel becomes a visual framing element, making the door feel more solid, well-centered, and distinctly architectural.
Although it is a dark color, its subtle light-reflective properties prevent the space from feeling confined; instead, it creates a greater sense of depth and openness.
