Stainless Steel On Galvanized Unistrut


Hi all,

There was an issue with the specs where the design had called out our electricians unistrut to be stainless steel on a galvanized cooling tower. What would be the best way to remediate this? Or do we need to get all new galvanized unistruts?

The best way to remediate this is to use what's called for in the specs. and that's to use the stainless strut. Makes no difference if the tower is galvanized. You'll probably need to use stainless hardware that's related.

The closeup picture of the mounting bracket shows you have installation issues too. There should be a couple of threads showing above the nut.

Good catch. Also that beam clamp in the pic above that should have a locknut.

If you believe it to be an issue submit an RFI to the Owner or Architect. If there is a change in cost just be prepared to give a change order.

Looks like that strut, the strut straps, and the strut "L' is the typical electogalvanized finish. The hardware appears to be zinc plated

Might want to double check the specs to see if all the hardware meets the requirements.

They aren't going to pay extra for anything that's in the existing spec book.

No, but if there is any question with regard to what is expected to be installed, a written RFI is the proper way to document.
