I was wondering what the vertical load capacity of a 4"×4"×.25" 6063 square aluminum tube is at 8' tall.
I have a small front porch with only the roof above it. There are 3 wood posts holding it up now, one on each corner and one in the middle. The porch is approximately 16'× 7'. Would it be feasible to use 3×3×.25 as well? Just looking to see what the likelihood of them failing is.
I live in the St. Louis area so large snow falls and high winds are possible but not a constant threat.
- Existing posts are 6×6 wood that are rotting away at the bottom
- I would like to keep the same post layout as that's where the bollards are
- Aluminum is easily accessible for me and and I won't ever have to worry about rot or splitting.
- Aluminum will be easier to work with especially by myself and I can always wrap it with wood down the road if I choose and that can be replaced when needed without dealing with braces and structural issues.
