What is a Cheap and Sturdy Metal Finish?

If you do not need brightness for nuts, bolts, fasteners used in cell site for cathodic protection, what kind of metal finish is cheap and sturdy.

I'm not sure I understand what you mean by "cell site", Ramon, but zinc plating is the most common and most economical method of cathodic protection. For a thicker coating and more protection, consider mechanical plating. Good luck.

Hot dip galvanize.

I would zinc plate instead of hot dip galvanise for fasteners as hot dip will tend to fill the threads up and render the fastener useless.
