I bought some used steel that had come from powerline pylons. it's already galvanized too. It's U-Channel steel 150mm x 75mm and 7mm thick in the web. i'll be using this for the posts.
And with one side of the pergola attached to the house, the other to a concrete wall, i'm guessing it's good for lateral/side forces.
