Deck Joists Parallel Elevation To Beam - Acceptable Approach?


Iíve been solicited to build a low profile deck (as low as possible relative to ground level). My thought was to build the deck so that the joists and beam are at the same elevation to achieve this low profile deck. I considered an option to install 2x8 joists using joist hangers against the 2x8 (x2) beams (instead of resting them on top and across the beams). From there the 2x6 decking would be laid across both the beams and joists and secured using deck screws.

Iíve seen this method used in deck construction, but Iíve never seen as an approved or recommended design. There are no codes for decking where this will be installed. Iím new to decks, are there any concerns with this approach from a structural approach?

Yep flush beam and joist hangers are totally an acceptable method assuming the rest of your deck meets local codes.

You just have to size the beam correctly. Hangers are fine.

Thanks, good to know. No deck codes here, but want quality a build either way.

Yes, Iíve done all the calculations for post/beam/joist spacing.

I believe proper selection and attachment of joist hangers would be more critical in this type of construction.

Yes it's fine. I do flush beams on low decks all the time.

Re: Deck Joists Parallel Elevation To Beam - Acceptable Approach?


My only concern would be the soil and the climate indigenous to where this deck is being built. Here in the Carolinas, with our warm temps and high humidity even top grade pressure treated lumber will rot too close to the ground due to moisture. It might be advisable to put in 4 to 6 inches of sand and gravel under the deck to make sure moister moves away.
