Acid Dipping ( or treatment ) of Galvanized Structures
Acid Dipping ( or treatment ) of Galvanized Structures
(OP)
I am not a reqular reader of this group but I think it would be the place to get good input.
I have recently run into a requirment for acid dipping a galvanized structure to take the "Shine" off the structure and make it dull.
The acid would be acetic.
Is it common to dip galvanized steel into an acid bath?
What does it do?
I think the difference between acid dipped and undipped steel would be about 6 months. Since the structures have arrived on site they have gotten noticeablly duller. I have worked with lots of galvanized structures but as far as I know none of them were acid dipped.
Thank you for taking the time to read this.

You could try galvannealed steel instead of galvanized steel. Galvannealed steel is dull.

Thank you for your prompt reply. Your answers cofirm my observations and suspicions.
The steel is about 5 miles from the ocean. Scince I started this tread it had gotten noticeable duller.
thanks again.
