Quick comparison of the melting points of aluminum and GI (Galvanized Iron) sheet:
| Material | Melting Point (°C) | Notes |
| Aluminum | 660°C | Pure aluminum melts at a relatively low temperature. |
| GI Sheet | 1425–1540°C | GI sheets are made of steel (iron + carbon) coated with zinc. Steel has a high melting point, while zinc melts at ~420°C. The steel core determines the overall melting point. |
As per Is 3614 material to be tested on 1029 degrees Celsius
