Product Description
HL Hairline Finish Duplex 2205 Sheet for Architectural Cladding and Curtain Walls
HL Hairline Finish Duplex 2205 Sheet for Architectural Cladding and Curtain Walls
Product Overview
Our HL (hairline) finish duplex 2205 sheets combine aesthetic appeal, high strength, and outstanding atmospheric corrosion resistance for coastal building cladding.
Problem Statement
304 or 316 curtain walls in marine environments show tea-staining and pitting within 2-5 years, requiring costly maintenance.
Solution
Duplex 2205 provides 10× the pitting resistance of 304, a uniform hairline finish hiding fingerprints, and higher strength allowing thinner panels.

How It Works
The directional HL brush pattern (grain 120-180) diffuses light and hides micro-scratches. Duplex structure resists airborne chlorides.
Selection Guidelines
For direct sea spray, use 2205 HL. For inland high humidity, 2205 is optional. Ensure matching anodized aluminum contact is avoided.
Frequently Asked Questions
Q1: Can HL finish be matched after welding?
Yes, with brush refinishing.
Q2: Is it more expensive than 316L?
Slightly, but longer life.
Q3: Does it rust in salt air?
Virtually no red rust.
