The 55% Al-Zn alloy coating provides dual protection through aluminum's barrier effect and zinc's sacrificial protection at cut edges, scratches, and damaged areas.
Excellent high-temperature oxidation resistance similar to aluminum-coated steel sheets.
High reflectivity value makes it an effective thermal barrier against heat transfer.
- Superior corrosion resistance at high temperatures
- Excellent abrasion resistance due to surface hardness
- Outstanding thermal and light reflectivity properties
