Re: double angle vs starred (cruciform) angle

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I have used 4 angle stars in truss design. They are pretty easy for the
fabricator. The intermittent gap plates alternate in both directions. They
are cheeper than HSS (for same weight), gusset easily and are available in
all sizes. I have never seen a shop detail for a 2 angle star.
