Rio?, nup, its hardly an industrial application. My quickset pier does the job, period. There is much angst on the merits of steel/concrete piers. Steel needs subbies=expensive, concrete=do it yourself. Steel is good for removing/low thermal mass (yawn, do you have a 32" RCOS, where its makes a difference?). A concrete pier is way strong enough. Have you heard of a collapsing pier due to no rio?
