Bonding galvi tubes on roofdeck

[newbie2723]

Hi all,

I'm sure this question is asked a ton! Putting 8', from floor, 3/4" galvanized sch40 tube on a roof deck for shade sails and string lights. The tubes will be a semi-permanent installation. Coupled to 4x4 deck posts. The sails will be quick up/down as it's too windy at times, and expensive, to engineer a fully permanent solution.

I had been worried about lightning strikes but after watching MikeHolt videos I understand you're not stopping lightning. And there are other taller structures within the noted 180ft (or 150ft??).

Even still it seems like a decent idea to bond these tubes so they don't charge individually from static etc. or worse a lighting cable becomes frayed and energizes one of the tubes.

Question: How do I couple a outside grounding wire to galvanized steel without introducing galvanic corrosion? There is an outdoor outlet on the deck I'm planning to run the wire to ground in.

Thank you all! the information on this forum is amazing.
