Contact SupplierCorrosion is destructive result of the chemical action between metal and its enviornment. It is the process of mrtal being worn away. If left unprotected, steel will react with surrounding enviornment and return to its more stable oxide compounds thus consuming the steel in the process.
The most reliable way to protect steel being Hot Dip Galvanizing, is the practice of immersing clean, oxide free iron or steel into molten ZINC in order to form a zinc coating that is Metallurgically bonded to the iron or steel surface.
The zinc coating process the against corrosion by providing protection to the iron or steel in the following ways:
S.No. | Fabricated Steel Articles | Minimum Value of Average Mass of coatings g/m2 | In Microns |
1. | 5mm thick and above | 610 | 86 |
2. | Under 5mm, but not less than 2mm | 400 | 57 |
3. | Under 2mm, but not less than 1.2mm | 340 | 49 |
