Corrosion Resistance: Galvalume Steel Sheet (Technical Data No. 2)
Overview
Galvalume steel sheet is a highly durable galvanized steel sheet developed by Bethlehem Steel Corporation in the United States, consisting of a coating layer composed of 55% aluminum, 43.4% zinc, and 1.6% silicon.
Features
Feature 1: Excellent Durability.
This steel sheet offers long-term corrosion resistance, and it is confirmed to be 3 to 6 times more durable than galvanized steel (Z27).
Furthermore, the corrosion resistance of aluminum is effectively balanced by the sacrificial protection and self-healing properties of zinc. This allows the alloy layer to naturally form over cut edges and scratches, preventing rust.
■Humidity Test (Temperature: 50°C, Humidity: 95%)
| Test plate | Time until red rust begins to appear |
| Hot-dip galvanized steel sheet (Z25) | 6,000 hours |
| Galvalume steel sheet (AZ150) | 35,000 hours |

2. Excellent heat resistance.
The galvalume steel sheet offers approximately twice the heat reflectivity of standard colored steel sheets because aluminum—the primary component—accounts for an exceptionally high 80% by volume.
As a result, heat transfer through the wall material is minimized, reducing operating costs such as electricity consumption within the facility.
■Solar Reflectance of Each Materials
| Materials | Solar Reflectance (%) |
| Galvalume steel sheet | 70~75 |
| Hot-dip galvanized steel sheet | 30~40 |
| Colored steel sheet (silver) | 50~60 |
| Colored steel sheet (gray) | 45~50 |
| Colored steel sheet (blue) | 10~15 |
