    All I wanted to know is what gauge steel 2″ tubular steel I need for a 6×10 trailer tongue.

      Interesting question, but I’m sorry, there is not enough information. Is this a 2000# capacity? From all my engineering, something in the 2″ range is insufficient for anything higher. People often take the tongue for grantid, but the interface where the tongue connects to the trailer bed is one of the highest stress point on the trailer. I’ve seen plenty of bent tongues, and you don’t want that problem. The size of material you need is a full engineering project — which, unfortunately, involves size yes, but also tongue length, configuration, tube orientation and design, capacity, how you will load it, and more. Way too much to answer here. I’m sorry there isn’t a simple chart to pick from.

    What gauge 2” square stock do I use for an 8’x16’ trailer that will carry up to 3000 lbs

      Are you talking about cross members or are you thinking about the main beams? I don’t think even full solid 2″ square will work for the main beams of a 16′ trailer. What will? That’s an answer that requires some engineering based on a lot more than just trailer length — like loading, intended use, other interacting structure, etc..

      I wondering if I can build a trailer frame with 3″ round tubing for trailer 6’*14′ holding 3000lbs max will use for tool storage. I have a fiberglass shell that will cover it. If you could give me any good advise. I was also consider 4″ c channel.

    Hello I’m interested to know what is the best steel for trailers construction and where I can find a trustful supplier?
    Thank you

      A36 is pretty standard. A500 or A510 are common for tube. Just make sure to use A36 or better. There are a bunch of different alloys available, so you might have to do some strength checking. For a supplier? You’ll need to look and ask around. Every area is different.

    Wondering what steel tubing I should use for a 16ft livestock trailer perimeter. Two 7000ib axels.

      It’s a good question that needs a lot more information and some engineering to answer. Good luck.

    I have a once camper now converted utility trailer that needs some work.. the cross members are Angle Iron/L channel that weld underneath the main beams that are C channel. No outside perimeter. All trailers, much like a truss on a home seems to have cross members on top for more of a even load and force downward.. would anyone agree I need to have a perimeter welded on as well as relocate the “frame” on top of the main beam.
