section class
 

section class?
hi everyone,
ok, this will probably sound like a dumb question, but i'm going to ask anyways:
what section class (class 1, 2 or 3) would a pl10"x3/8" belong to? (10" is vertical)
the reason being, i've received a design for a ships ladder with that plate as a stringer and i want to check if it meets the requirements compared to what we usually see (ex. mc or c sections).
thanks in advance (and thanks for not laughing)
have a good one everyone.
i never designed stairs like this. however, i have seen them in many applications. it seems practical although it is not the usual construction of channels. the treads will provide lateral stability and will cut the unbraced length.
good luck
take a look at this site and see if they have the information you need. we had quite a few of them on our site. takes a little getting use to but work well in tight places. never been able to carry a load on these stairs as their old ads depict.
