I'm building a carport and have been advised by theoretically knowledgeable people to add steel cross braces for better wind stability. I was thinking of using threaded rods between the posts - but how do you attach them to the posts? Drill through the post and nail plate? The nuts would then be at an angle - are there construction brackets that fix at about a 45-degree angle?
In the roof, I will have band steel corner to corner, but attaching that isn't difficult.
