C- U- channel shaped beams/ Differences?
C- U- channel shaped beams/ Differences?
(OP)
Hi, i'm trying to get the difference between C- U- or channels shapes. It's reasonable to me that both U- and C- may be called channels. But providers often call U- and C- to the same beam and codes state distinctions.
Are there implication about hot rolled or cold-formed? (saying one is cold formed and the other rolled)
I also have seen square and round corners at web/flange junction
which are the expected differences?
thanks

Cold formed cee shapes will have the lips, because otherwise local buckling of the flanges greatly reduces the strength of the member.

A "U" shape is usually trimmed from a square tube steel with uniform and equal leg and web thicknesses, and a height based on the original square tube steel height. Each edge of each leg is usually ground off square and burrs removed. The corner is as it originally was from the original tube steel: rounded inside and outside.

My problem is that i'm trying to specify a C beam and started to look for available commercial dimensions at local site in order to check their resistance. I want to work with the cheaper C cold-formed channel that withstand stresses, and by seeing local providers i noticed they call "C-shape U beam" to the same member. So i'm trying to deduce which kind of beam they are based on the pictures at websites
I'm assuming that square corners should be hot rolled. but i haven't found a clear difference between U- and C-beams (if there is one)
