Galvanizing lead times

There is a perception that hot dip galvanizing is a very time consuming process that takes weeks, not days, to be completed. The reality is quite different.

Turnaround time of 24 hours can be Arranged

The actual process of dipping steel in molten zinc takes just a matter of minutes. What takes slightly longer is the preparation beforehand. The steel must be hung on jigs, cleaned, rinsed and fluxed before it can be galvanized. Afterwards, it must cool (the galvanizing bath is at about 450°C) and be taken off the jigs. The time to do all of this is only a few hours. In practice of course, there is other work being processed too, so the typical turnaround time is about three days.

All these operations take place in a factory environment which is unaffected by the weather. The coating does not have to cure or dry out and it will not change its hardness. This means that the steelwork can go directly to site and be erected. The coating will normally resist the knocks and bangs of site handling that could seriously damage other types of coating.
