Constructing a covered walkway from driveway to patio, and also covering the patio. The walkway is envisioned to be a raised "boardwalk" type, set on stringers attached to the posts which extend 8' upwards, to support typical trellis members and a "roof" of translucent corrugated polycarbonate panels. Will be sinking sono-tubes to form the post foundations, and setting the posts off the concrete with simpson fasteners. Some of the lighter framing members may be galvanized structural hat channels, for a more contemporary industrial look, and all the wood will be painted white. My question is, if nothing is touching the ground, and everything is painted, what is the most economical material to use? Seems a waste to paint cedar, right? Can I use pine? Also had an idea of using recycled wooden pallets as a modular boardwalk. They are free all over Craigslist. If those are elevated as well, and captured by stringers, would those work, do you think? Thanks in advance!
I have about 1000 sq ft covered wth a pergola - all rough hewn douglas fir - local lumber yard provided and did the corbels as well. Two coats of primer and two paint cover. Built it about 6-7 years ago, will probably refresh the paint next year.
