Calculator says for 500lbs:
>60" span? 1-1/4 0.072 (15 ga)
>30" span? 7/8 0.083 (14 ga)
Seems like overkill. I'm hoping to keep it light to allow the woman homeowner to use it.
Green being the square steel (yup, hollow - I was thinking 0.12") and red being where it'll rest on. My gut says 3/4" would be fine, even likely 1/2", but I don't have anything to base that off of.
It's a small deck that shouldn't have more than 2 people standing on it at a time, but I'd like to exceed that for safety sake. It'll certainly never see a heavy load like machinery.
