What are Scissor Trusses?

Scissor trusses are made with double bottom chords that meet in the center of the truss and “scissor” together, crossing over the king post and continuing onto the top chord. They are a bit more expensive than king post trusses, but give some height in the middle of the room. Scissor trusses tend to spread a little when they are loaded. They act like the leaf springs on a truck. As snow piles up on the roof, the truss will squat down and spread out from wall to wall. We engineer the truss deflections to less than half an inch, so the spreading doesn’t effect the interior finishes.
