I cannot find these thin H shapes "yet" in any hand book, but they do make them for the Manufactured Housing market. They call them MH beams or thin I beam. Here is one mill that makes them. So far that is the only mill I can find them on the web that does. I'm sure there are more, just I have not found them.

You will notice they offer a 10 x 8#/ft and a 10 x 9#/ft which I have and it has an area moment of inertia of 35.5 in.^4th.

Thanks for posting that link. Interestingly I think we have done some business with those guys in the past on something. I don't remember all of that stuff but my estimator will. I doubt you'll find any info on those MH beams in any bible, either printed or the net version. To me those are custom pieces. Maybe not so if you're a manufactured housing builder, but the website also seems to indicate they'll run those to order. I've got a fab guy I use for small stuff who used to be one of "the guys" at American Bridge. If it was made in the last 100 years and has published info he'll have it, or know where to get it lol. That's if he has not keeled over lately as he's about 85 but still going at it...I think.

On a side note reading through the company history, those WV guys may have been the inventors of the micro mini mill. Back in the day there were many here around Pittsburgh, not so much now days.

Hi Ralph, if by chance you can get any kind of info on these MH beams, I would be very interested in getting a copy etc. Your not going to find these in the Manual of Steel Construction...

The old guys who knew all this stuff... Yes, they are becoming fewer and fewer all the time. I'm getting closer to being in that category, retired but not quite close to his era.

I'm going to have to start looking close at the new campers on dealers lots for the welded H shape. I had not been looking for that so never paid too much attention. Now the new thing is 8" frame on 10,000# GVWR campers. I will never own one. 10" is the bare minimum in my book on anything in the 30 ft range. They keep cutting everything to the bare bones worse than they already were.

Thanks
