Have you considered how your Patio Cover will fare in a wind storm?
In April ,2011, 62 wind storms took 248 lives, injured more than 2000 people and severely impacted Alabama.
I advise you to get professional design opinion before attempting to construct what may become a 225 sq ft metal sail. You border on the Zone IV wind zone and you border on a Hurricane Susceptible Region.
