This is a pic of a site on the latrobe highway. I thought this was a good picture to show, as many connections can be seen. First we can see the rafter to zed purlin connection. There is a cleat holding the zed purlin up, which is welded onto the rafter. Mesh and insulation with sisalation is then layed over thye zed purlins, then the roofing is screwed down through the zed purlin. Two steel members are also bracing the sides of the rafter, helping stabilise this section.
