When calculating beam span, the general rule of thumb is pretty straightforward: the longer a beam spans, the bigger it needs to be to support that span. That is a fairly simplistic way of looking at it. To calculate beam span, you need to consider the wood species and grade, size of ...
3-foot-square deck needs refinishingPeter Hotton, Globe Staff
Evolution beams are designed for long spans between support columns. Measuring 2 inches by 11 inches, the rectangular beams can be either a single or double, depending on the load and span. They can also function as either drop or flush beams. The longest beam span on this deck was 15 f...
We chose a simple pergola design, and wanted a wide overhang with curved beam and joist ends to dress up the basic square pergola. Our pattern was about 2′ long on the boards. If you choose square ends for your beams and joists, or a simpler shorter decorative curved end, you may not...
Install the outer joists and the central beam on your concrete blocks. Use pressure-treated lumber for resistance to decay. Ensure all are level and secure them using galvanized nails or deck screws. Step 2: Square and Attach Check the squareness of your frame by measuring the diagonals; they...
Because of the added weight of the outdoor kitchen components and the furniture that the clients planned to use on the deck, we doubled up the single Elevations 2x8 galvanized steel box beam that we would have normally used to support the joists on a deck this size. This upgrade also giv...
This proves that despite using higher-grade steel characterized by more significant CO2 emissions, the mass reduction associated with the refined design leads to an overall lower environmental footprint. This fact underscores the importance of selecting proper steel grades for steel to achieve an ...

math. 1” deck board (5/4”) + 9 ½” (10” joist) + 9 ½” (10” beam) = 20” of structural material sitting on the post, so 50” – 20” = 30”. The adjustable post brackets allow for any final adjustment. I would need two 8 foot 6” x 6” posts to get my 6 ...
Beams at each level should be connected to the post face with manufactured hardware sized for the calculated beam load to the post (Figure 6). The post needs to be wide enough for the attachment, which—depending on the hardware—may require you to increase the size of the post. Steel ha...
