Thank you for explaining that Jai Pal. I voted, but also sharing my preference here…
I voted #1, preferring all steel: No wood to rot, concrete walls/columns to crack, or fabric to fray. Steel can rust/corrode, but lasts longer when protected by paint or has rust inhibitors (galvanized).
Likely any project is too late for shade in the next couple months, so may as well pick the best long-term solution and be cost effective. Also, the flat/sloped roof will lend itself well to solar panels if we desire that.
Happy voting, may your favorite be the winner.
