    Bed frame strength?

    Would a bed frame be strong enough to use for loading ramps on my car trailer? They would be spanning 13".

    No.

    Too thin of a cross section, and not enough sectional depth.

    Car trailer and bed frame rails do not belong in the same sentence.

    He didn't say he was building a trailer out of a bed frame, just 13" ramps to get the car on an existing trailer. If you have enough of about anything it will be strong enough, the question is at 13", how much will a bed frame support.

    That said, I would just buy some ramps or some steel and do it right, but that doesn't mean it wont work.

    Re: Bed frame strength?

    Loading ramps for a car trailer means or implies that a car will go across said ramps.

    I've bent bed frame rail by standing or pushing on it. A 5 ft piece, blocked at the ends and push/stand/stomp in the middle in order to correct a bend.

    So without LOTS of reinforcement to the tune of 'is there even a piece of bed rail angle iron in there at all', no way is bed rail appropriate for ANY load-bearing part of a car trailer. IMNSHO.

    Some pieces of bed rail (aka small size and small gauge angle iron) could be used to box-out the trailer lights or such. But not anything structural on a car trailer.

    Re: Bed frame strength?

    No worries, I just had a stock pile of bed frames and was thinking of what i could use them for. I am redoing the loading ramps on my trailer and the main support rails are 1/4" thick 2"x2" angle and there was existing 2"x2"x1/8" "rungs" (for lack of a better word). Those rungs are what I was going to be replacing.

    For replacing the rungs, you probably are ok. Just understand that the welded areas on the 2x2 will be affected, and you might see some bending there. I suppose adding material all over the place will shore up any issues, on a simple ramp.

    I may be wrong, but I think bed frames are hard and brittle and are prone to breaking as opposed to bending.

    Not wrong trapper, I'm not sure of the brittle and how much. Fredman Bros in Peoria last I knew made bed frames (been a bit back). And punched the frames in press brakes, it sounded like someone busting AR or shotgun blasts (whichever). The company I used to work for repaired the presses when they stress cracked.

    Why are the angle "rungs" turned that way? Thasts just the first I have ever seen them turned like that.

    Loading isn't such a bumpy ride that way, but they do tend to catch ****. I suppose those particular ramps will empty out when you flip them up though.

    Re: Bed frame strength?

    Isn't bed rail too hard and brittle, crap to weld and a &itch to drill? Maybe yours differs than what you get around here.
    13" isn't that much of a span.

    Re: Bed frame strength?

    As I know bed frame rails, they are plenty strong; most of them are made from recycled train track. They're just poor candidates for welding due to their high carbon content which frequently leads to underbead cracking.

    The bed frame rails I've seen are attached to their end brackets with rivets, not welds. I guess the bed manufacturers know the limitations of their materials. Take a hint from them.

    Re: Bed frame strength?

    The only time I ever tried to use bed rail for something I soon realized it had some kind of toxic smelling finiish/paint ?? and regardless of how much cleaning I tried the steel had a lot of impurities so the welds were pathetic... even for me
    I suggest you take these rails to the local scrap buyer and get top $ and send them BACK to China

    enjoy

    Re: Bed frame strength?

    i knew a guy who tried what your thinking about doing. his ramps were about 2- long and were for loading zero-turn mowers onto his 6000lb tandem. the mower made it halfway up and the ramps cratered and got nasty bent up......

    like said before - bed frame rails and ramps dont belong in the same sentence

    Cool, thanks. Makes sense i guess. I was thinking car trailer wise. Mine slide under and were put the other way.
