Galvanized steelwork can be subject to staining and discolouration which can sometimes be mistaken for failure of the coating and rusting of the base steel.
There are numerous reasons why such staining may take place.
Read the datasheet for more information on post galvanizing defects:
- Surface contamination
- Weld seepage
- Seepage staining
- Swarf contamination
- Timber staining
- Water staining
- Rusting of unprotected parts
