A flush or header beam is a structural member positioned at the same level as the joists and uses joist hangers for attachment just as you would at the ledger board. Flush beams are commonly used for framing angled deck forms such as octagons or on stair landings where a cantilevered beam would be less practical.

In many designs with short beam spans or short joist spans, a single ply is sufficient as a beam. … As shown in the table below, a single 2×10 beam can span 6 feet while carrying 2x8s spanning 8 feet and cantilevering another 2 feet. Lesson: When beam spans are less than 8 feet, you may be able to use a single-ply beam.

How far can a 2x10 span without support?

A 2×10 beam – made up of two 2x10s nailed together – can span up to 11′ without support beneath a deck that is 4′ wide. For a more normal-sized deck, the same beam can span 8′, supporting a deck that is 8′ wide.

How far can a deck span without support?

What is deck beam span?
