| (1) Surface appearance |
| |
Photo-6 shows surface appearances of different hot dipped coated steel sheets after 10-year atmospheric exposure tests. (See page 12-13) |
| |
Table-6 is the condensation of the results: |
|
| a) |
Singapore: No major difference noted among W.R.Alstar and 55% Al-Zn. Galvanized has red rust all over and thus is inferior in corrosion resistance. |
| b) |
Manila: No major difference noted among W.R.Alstar and 55% Al-Zn. Galvanized has severe red rust all over and thus is inferior in corrosion resistance. |
