- Q: Want to construct a patio cover approx. 20 feet long. Only want to use a 6x6 or 8x8 post at each end. What size steel i-beam would I have to use to carry the load???
- First of all is it a rule of thumb with carpenters and ironworkers never to set steel on wood. I would use a 14 tall (2) ply lvl header. *Laminated veneer Lumber. This will hold the weight of the structure between your posts. A steel beam would be quite costly today as prices on steel have skyrocketed, plus you would need a boom truck or small crane to set this beam, and you would need some sort of mounting bracket or holes pre-drilled in the beam ends to secure it to the posts. Plus you would need to have the beam delivered and if your patio is in the backyard - you would need another pc.of equipment to get it around back. Advice from me is to go with an LVL beam. They are 1+3/4 Thick and you would need a (2 ply ) beam, which means you set one pc. and then laminate another one into the first. Glue between layers (use heavy duty liquid nails) and then Lag screw them together. Use 5/16 x 3 lag screws with a washer on each one. Pre-drill holes about 3/16 smaller than lag screws - then insert lag screws and tighten up with an electric impact.
