City Permit Question - Galvanized Steel Ban
I submitted plans to the City for a steel frame structure that is fully exposed to the elements. They have a ban that restricts all galvanized steel (leachable metals is the actual wording). I thought this was weird since our bridge standards allow galvanized railings, etc but oh well, that’s not the point.
An alternative to galvanized steel is powder coating. I don’t want to do weathering steel, but it is an option I suppose.
The City also mentioned that there is a coating that can go over galvanized steel but he wasn’t sure what the exact name is. Anyone know what this is??
Also, the City said that galvanization is OK as long as they see a certificate guaranteeing a 50 year lifespan. I asked my fabricator and they said they can’t provide this.
