I'm looking to build a 4 posted porch extension. 4x6 posts. The top will be boxed in with 2x6 and then 2x4 boards running parallel to each other spaced about every 1.5ft or so. It will be an open top. I have heard that Redwood is not recommended for load bearing applications. Is this true?
Do we NEED the redwood, no. I'm thinking of using it because of its exterior durability. What other lumber would be good for this application? I don't mind staining/treating for water protection.
