Hairline Finish Stainless Steel Sheet
Hairline finish stainless steel sheet (HL finish, also called No. 4 finish or long-grain finish) has fine, continuous parallel lines that run the full length of the sheet, creating a non-reflective directional surface. The finish is produced by polishing cold-rolled stainless steel substrate with 150 to 240 grit abrasive belts in a single linear direction. Surface roughness typically falls between 0.2 and 1.5 microns (Ra). The directional grain conceals fingerprints and minor scratches, which is why it is one of the most specified surface treatments for elevator panels, architectural cladding, and high-traffic interior surfaces.
Hairline finish sheets are available in thickness from 0.4 mm to 6.0 mm, width from 1000 mm to 1524 mm, and length from 2000 mm to 3000 mm. Standard sheet sizes are 4x8 ft (1219x2438 mm) and 5x10 ft (1524x3048 mm), with custom cut-to-length and slit-to-width on request. PVD colour coating in gold, rose gold, bronze, black, champagne, and silver adds decorative value, with anti-fingerprint treatment available on all variants.
Stainlessinox LLP manufactures and stocks stainless hairline finish sheets at our Khopoli processing facility, supported by our main office in Lower Parel, Mumbai. With over 3 decades of stainless steel industry experience and ISO certification, we maintain one of India's largest decorative stainless steel inventories and ship pan-India to architects, interior designers, elevator manufacturers, appliance manufacturers, furniture manufacturers, signage fabricators, and shopfitting contractors for lift cabin panels, architectural cladding, wall panels, furniture, kitchen equipment, and signage projects.

Hairline Finish Stainless Steel Sheet Types
We supply 4 types of hairline finish stainless steel sheets, each designed for different aesthetic and performance needs: mirror hairline finish stainless steel sheet, satin/brushed hairline finish stainless steel sheet, PVD coloured hairline finish stainless steel sheet, and anti-fingerprint (AFP) hairline finish stainless steel sheet.
Mirror Hairline Finish Stainless Steel Sheet
The mirror variant uses an 8K super mirror-polished stainless steel base. Its high-gloss surface produces defined and distorted reflections across the ripple contours. This creates a liquid-water visual. Hotel lobbies, retail displays, and residential feature walls are the most common uses for this rippled mirror finish.
Satin / Brushed Hairline Finish Stainless Steel Sheet
Satin and brushed variants start with a No.4 directional grain or non-directional brushed texture before the ripple stamping process. Lower reflectivity helps mask fingerprints and surface marks. Elevator cabins, corridor panels, and office interiors benefit from the more understated appearance of these stainless steel decorative sheets.
PVD Coloured Hairline Finish Stainless Steel Sheet
PVD hairline finish stainless steel sheets carry a vacuum-deposited titanium colour coating that resists scratching and UV exposure. Available in gold, rose gold, champagne gold, black, bronze, sapphire blue, silver, and green. Each colour shifts in tone as light moves across the hairline finish stainless steel sheet texture, adding a dynamic visual to wall panels and ceilings.
Anti-Fingerprint (AFP) Hairline Finish Stainless Steel Sheet
AFP hairline finish stainless steel sheets include a transparent nano-coating applied over the mirror or PVD surface. The nanoINOX coating repels oils and water, reducing smudge marks and simplifying maintenance. Elevator panels, kitchen equipment, and other high-touch surfaces benefit most from this variant.
Colour Options (PVD Coating)
PVD (Physical Vapour Deposition) applies a titanium-based colour layer in a vacuum chamber using cathodic arc deposition. The coating thickness are 0.3 to 1.0 microns. It bonds at the molecular level and doesn't fade, peel, or discolour over time.
We coat hairline finish stainless steel sheets in 7 standard colours. These include silver (natural), gold, rose gold, bronze, black, champagne gold, and custom PVD colours on request. Gold hairline stainless steel and black hairline stainless steel are the two most specified PVD variants for elevator and architectural work in India. Anti-fingerprint treatment can be applied over any PVD-coated surface.
Hairline Finish Stainless Steel Sheet Industrial Applications
Hairline finish stainless steel sheet serves 5 application categories: elevator panels and lift cabin interiors, architectural cladding and building facades, interior design and furniture displays, retail and hospitality spaces, and kitchen equipment and appliance panels.
Hairline Finish Stainless Steel Sheet FAQ
Common questions about our hairline finish stainless steel sheets answered by our technical team.
Hairline finish (HL) is a linear polishing treatment where fine, continuous parallel lines extend uniformly along the full length of the sheet. It is designated as No. 4 under ASTM A480 and HL under JIS G4305. The finish is created by polishing cold-rolled stainless steel with 150 to 240 grit abrasive belts in one direction. Surface roughness typically falls between 0.2 and 1.5 microns (Ra). The result is a non-reflective, directional surface that conceals fingerprints and minor scratches.
Hairline finish has long, continuous grain lines running the full sheet length (long-grain), while brushed finish (satin) has shorter, overlapping brush strokes. Both fall under the ASTM A480 No. 4 classification. Hairline vs satin finish stainless steel is largely a difference in grain continuity and visual character. Satin appears softer and more uniform; hairline appears sleeker with a defined directional pattern.
Choose a hairline finish for high-traffic areas like elevators, lobbies, and corridors, where fingerprint and scratch resistance matter. Choose a No. 8 mirror finish for decorative surfaces where maximum reflectivity is the priority. Hairline is lower maintenance. Mirror requires frequent cleaning to stay presentable.
2B is a mill finish produced by cold rolling, annealing, and pickling. It has a smooth, slightly reflective surface with no directional grain. Hairline finish is a secondary mechanical polish applied over a 2B or 2D base, creating fine directional lines through abrasive belt contact. Hairline is a decorative finish; 2B is a standard industrial starting surface.
Hairline finish stainless steel typically has a surface roughness (Ra) between 0.2 and 1.5 microns. This range is produced by 150 to 240 grit abrasive belts polishing in a single linear direction. Finer grit produces a lower Ra value and a sleeker visual appearance. Coarser grit yields a more visible directional grain.
Yes, hairline finish is a popular finish for elevator panels, lift cabin interiors, and escalator cladding. Its directional texture conceals fingerprints and minor wear from daily contact. SS hairline finish lift installations are common across residential, commercial, and hospital elevators in India. Anti-fingerprint coating and PVD colours add further durability and aesthetic options.
Standard sizes include 4x8 ft (1219x2438 mm) and 5x10 ft (1524x3048 mm). Thickness ranges from 0.4 mm to 6.0 mm. Width options are 1000 mm, 1219 mm, 1250 mm, 1500 mm, and 1524 mm. Length options are 2000 mm, 2438 mm, and 3000 mm. Custom cut-to-length and slit-to-width are available on request.
Yes. PVD titanium colour coating is available in gold, rose gold, bronze, black, champagne, and silver. The layer measures 0.3 to 1.0 microns and bonds at the molecular level. It won't fade, peel, or discolour, and anti-fingerprint coating can be added on top of any PVD-coated surface.
