Hi everyone. My first time here so I'm just finding my way around. I need to fix a 6x2 (8ft) wall plate to the back of my house. i intend to attach 5 6x2 trusses (10ft long and at 24inch centres) and make a covered area outside my back door. kinda like a car port or pergola. My questions are: Do these wood dimensions seem fine to polycarbonate sheeting ? regarding fixing the wall plate to the wall.... what would you suggest i use? I hope this makes sense and thanks so much for you advice in advance.
