Stainless Steel Hairline Finishing
Stainless steel hairline finishing is a directional surface grinding process to create consistent linear textures on stainless steel panels. It is commonly used for elevator panels, kitchen & bathroom hardware, architectural decorative sheets, food processing machinery and sheet metal parts, with strict requirements on straight texture, uniform gloss and no thermal discoloration.
After rolling and welding, stainless steel sheets carry oxide scale, weld marks, dents and scratches. Hairline finishing improves appearance, reduces surface reflection and enhances fingerprint resistance and corrosion resistance.
Lean Abrasives’s high-precision abrasive belts are designed for continuous stainless steel hairline lines. Zirconia and silicon carbide grains are available. Coarse grit removes defects rapidly, while fine grit produces straight, uniform lines and avoids thermal discoloration.
Our non-woven abrasive roller brushes are used for post-finishing, residue removal and weld blending. The flexible grinding structure prevents over-cutting, suitable for soft hairline on food-grade stainless steel and thin decorative sheets.Polishing wheels, flap wheels and abrasive discs are available for offline rework, local defect repair and manual touch-up of stainless steel workpieces.
