joining deck beams together

And now there are versions for outdoor use. It may not be cost effective to frame an entire deck with engineered lumber but installing an engineered-lumber drop beam is a great way to reduce the number of posts and footings needed to support a deck.

When securing 2 or more dimensional wood boards together to form a beam you will need to use the proper number and size nails to create a solid member. A 2x10 Beam should use a minimum of (4) - 3” nails fastened in a vertical pattern from both sides of the beam every 16” on center. 【Get Price】

@awithrow - if you are building a beam from 2x wood you can build a 20ft beam by staggering the 2x's then gluing and nailing them together. So for example one side would be 2 10' boards end to end and the other side would be a 5' board a 10' board and another 5' board. 【Get Price】

In decks that extend more than 16’ out from the house a similar beam is installed parallel to the house at 16’ so that joist ends can overlap on top of the beam since 16” is the span limit of 2x8 joists. 【Get Price】

Overlapping seams integrates strength and prevents fracturing along seams throughout the length of the beam. Always split a beam over a post. Plan ahead and layout the beam on the ground over the footings before installation. For instance you could use 2-2x10x10’s and 2-2x10x20’s to form a 30’ beam with one seam set above two intermediate ... 【Get Price】
