430 Hairline Finish Steel Sheet HL Polish ASTM A240 0.5-2.0mm 1500x3000mm for Architectural Trim Application
430 Hairline Finish Stainless Steel Sheet - HL Polish
The 430 hairline finish stainless steel sheet with HL (Hairline Long Grain) polish features a distinctive continuous linear grain pattern that flows along the length of the sheet. Manufactured by TISCO to ASTM A240 and JIS G4305 standards in the large 1500mm x 3000mm format, this sheet is engineered for architectural trim and facade applications where visual continuity is paramount.
Key Features
- HL Hairline Finish: Continuous longitudinal grain pattern created by precision abrasive belt polishing, delivering a sleek, modern metallic appearance with consistent visual flow
- Large Format Size: 1500mm x 3000mm (5ft x 10ft) dimensions minimize joints in facade applications, creating seamless visual continuity across large surfaces
- Weather Resistance: 16-18% chromium content provides reliable atmospheric corrosion resistance for exterior architectural applications in moderate environments
- Directional Consistency: Uniform grain direction across the entire sheet surface ensures professional installation alignment and aesthetic cohesion
