Post frame construction (pole shed, post-in-ground) is the use of solid wood or multi-ply laminated wood columns that are fully treated or treated to a minimum height where the post will be in contact with the ground.  These posts or columns are embedded in the ground 5’ and set on a precast concrete pad every 6’-12’ on center depending on the type of structure and notched at the top to set a truss.  A pre-engineered wood truss is then set on top of this post and either bolted or structurally lag screwed to the side of the notched column.  Once all posts and trusses are set, a row of 2x4 (over top of truss), 2x6 (set in hangers between truss), or 2x8 purlins (set in hangers between truss) will be fastened every 24” o. c. or less from the peak to the eave and covered with roof steel.  Also a row of 2x6 girts every 30” on center or less will be fastened to the side of the wood columns and covered with steel.
