    Default Treated pine beam span


    I'm putting up a freestanding patio (5 x 2.6m) with insulated roof panels on top. I've got 6 post footings at the moment but wanted to eliminate the middle 2 posts and just have 4 posts. If I'm using treated pine what size beam would span the 5m? Or is that too far? Insulated panels are 8.7kg/m2. Not 100% sure how to calculate RLW. Low class wind area.

    Hi Dan,

    Just Google "Treated pine span table" and you'll find plenty of options to find what you need, depending on your rafter spacing, roof load, etc. Here's an example for you.
