Span capabilities of L4x4x1/4

Span capabilities of L4x4x1/4

Span capabilities of L4x4x1/4

(OP)
Building a pier/dock using 20' sticks of L4x4x1/4"  steel (left over from other job..free).  How far can I span using the L4x4x1/4 as beams between piers (wood in mud).  Decking specs are 50 psf total (10 dead and 40 live load).  Will this support a 2' cantilever?

Do I need to double the beams (one on each side of the pier)?

Decking joists will attach to the beams with decking on top.

thanks ray

RE: Span capabilities of L4x4x1/4

Sorry, but, for liability reasons, and others, we do not do structural engineering for specific projects in this forum.  

It would be best for you to contact a local structural engineer for the answers to your questions.

you could still at least outline a simple strength calculation

@loki3000, if there was a such a thing!

An angle is non-symmetrical and a lack of understanding of the consequences of this can lead to problems. With one leg vertical, and a vertical load, the angle deflects downward and sideways

@rlw030, If you must try this, do a web search for beam theory.
