Technical Specifications & Manufacturing Range

Key Performance Advantages

1. Superior Anti-Corrosion Protection:

Achieves salt spray test resistance ≥1000 hours (ASTM B117) at 100g/m² zinc coating, preventing rust in coastal and industrial atmospheres.

2. Excellent Formability & Ductility:

Capable of 180° cold bending without zinc flaking or cracking, making it ideal for deep stamping, roll-forming, and high-speed profiling.

3. Versatile Surface Finishing:

Passivation and anti-fingerprint options provide an enhanced paintable substrate and improved resistance to water staining during transit.
