so is there any one who knows steel # better then me on here.my ? is this,i have built alot of diffrent trailers for myself and other people,but this one blow's my mind.i get this call from a guy who want's me to build him a 48ft 5er tripple axle .36ft deck,4ft dove and of corase the 8ft neck.i said ok that is the same thing i just got done building for myself.so he say's he has a i beam frame that he want's me to use ,so i said bring it by and i can take a look.he show's up with a 60ft trailer house frame and he want's me to use it for all of the build!ok the frame is 10'' x1/8'' i beam ,it is also doulbled up over the axle's and a good portion of the rest of the frame for the deck area.that part dosnt bug me ,for we just built a 30ft pull behind for a freind with the same kind of frame .what bug's me is when i build a 5er i use 10'' 15# per inch chanel for the neck because it is easyer to work with than the i beam.is this 10''x1/8'' i beam going to be strong enough for this trailer neck and up right's? he want's to haul car's from down south on it and also small tractor's .i don't need to build this and have it break on the road and have to deal with insurance .i tried to talk him into the channel but this is a bugget build.he is already crying about the decking price.i do need this build it has been slow here all winter .so if anyone can shed some light on this please do.thanks in advance.

How wide is the flange on this 10-inch S-shape? Are you sure it’s an S-shape, and not a W-shape? Closest any of my books come is a W-10X12, which has a 3/16-inch thick flange and web. The flange is 3.960-inches wide. None of my books will give loads for either beam this small anyway! If you give more information maybe I can find a beam twice the size, and cut the loads in half. I know that is not the proper way to do things but might give you some ammunition to convince this guy to buy larger shapes!

Well, he won't be able to use a 40ft deck loaed with tractors, unless garden tractors, as he will be over weight with 3 typical smaller antique tractors. About 20ft+5 is a acceptable length for those loads as you just can't haul that many tractors at one time.
The second problem will be the tri-axle configuration in that length. You will over load the axles and tires plus scrub the tire off the wheel in tight turns. A dual tandum/single axle is needed here depending on design weight.
The reason why a MH can use such light I-beam, is the vertical box frame design carry's part of the total weight. Think of the box design as a truss built bridge being strong as a package but weak individual componets. Second the MH trailer design is not for OTR use, but typicaly less than 10pulls in it's life span.
I-beam steel configurations cost less to build with than channel iron as I-beam costs less per pound and builds twice as fast.

Buy UNION work UNION. It pays off in the long run Define Union: A labor Union is nothing more than united workers with a common goal for better working conditions.
We all are in some sort of labor Union, some are just larger than others with better working conditions!
chyrel,the flange width is 2and 23/30's'',so almost 2and3/4''.there is no wedge in the middle,it is like a flat bar and plate where set together.so i think it is a S shape iron.any rate would be helpfull.

tell him to do the channel and do mesh with angle iron instead of decking

dot said they have no prblem with it ,but it must have the trailer-utility type tire on it.
if the trailer passes dot inspect and he is happy with it there will be a form signed saying there is no warranty and i am not responsible for damage,if he still want's it built.

there is no wedge in the middle,it is like a flat bar and plate where set together.so i think it is a S shape iron.
That would be a W-shape / wide flange. The inside of the flange of an S-shape has a 16 2/3° angle if memory servers. Another trick to beef up a beam is skip weld flatbar to each flange; say a 6 on 12 weld. But by the time you add your labor, and materials might as well buy larger shapes.
FYI, my book says a W-10x21 at a 21-foot span uniformly loaded is only good for 13.7 kips, or 6.85 kips point loaded in the center.
T_Bone brings up some really good points! The smart money says you can’t get there from here!

The only beam I can find with a 3/16" web x 10" with a 2-3/4" flange is a M10x9 with maximum span of 21ft@5.9kips and that's not going to hold much rolling load weight.
I have a 28ft tri-axle tag trailer and if you load it too 10k, put the trailer into a hard turn on dirt, stop and look at the trailer tires, the side walls will be rolled over on the rim. I would hate to see what the tries look like on black top
I have to agree with Chyrel, it's hard to get there from here.

M shapes are also called jr (junior) I beams. They aren't in manuals of standard structural shapes because they are not suitable for constructing STRUCTURES such as bridges and buildings. My father was in the steel fabrication business for 30+ years and taught me this lesson when I couldn't find an odd shape in his manuals one day.

HA! Learned something here today! Thanks for sharing that Phillipmc1268!
Maybe that is why my “Manual of Steel Construction” book only has half a page in the “M-shape” section.
Out of the bazillions of tons of iron I’ve placed in my life, I can’t say I’ve ever worked with an M-shape. Looking in the manual all the M-shapes do seem on the light side, a M-5X18.9 seems to be the heaviest per foot.

so basicly this beam won't span the frame from where it gose from doubled up to the neck witch is about 15ft. if i got him to shorten the frame a little and box the front beam for the neck,would the beam be stong enough for the 8ft span of the neck and the 4ft up right's.there is a good portion of wieght on these parts.

so this is what i have come up with i got him to get it down to a 30ft deck and 4ft dove.the frame will be doubled side buy side like it is for 20ft over the axles,that will span the hole 30ft of the deck.i will use the channel for the up right's and the neck.on the front of the deck there will be a plate welded to both beam's and the up right's willl be welded to that making it a uniform joint.will this be a stong enought frame for the trailer build.also i will drop the front axle so it is a tandom.
