    strong enough for pickup truck or car frame ??

    Could I use 1" square tube 11ga or is that too small for a custom built ??

    why stainless?... regular steel might do, it's cheaper and less prone to cracking..

    will it be to support a floor or be used as chassis rails as well?...

    Are you building one of those cool “prepper” vehicles?

    It's a structure. Load matters. Geometry matters. Your 2" 11 ga. square tubing could be ok in a proper design. Or it could fail.

    If you need to ask , you have no place in building it .

    Not enough info provided to even begin to answer beyond some general guidelines.
    "Frame" could be anything from a bed floor structure to a structural chassis structure or component.
    Beyond structural design and application, one must consider the cost of material and labor (IE: fabrication and welding)
    The most common material used in OE or aftermarket fabrication of chassis components would be for example 1080 dom mild steel in various shapes and sizes. 2x3" and 2x4" main frame material and 1 .75" round tubing for bracing, roll bars etc is common. Wall thickness varies by specific application and area. It is the lowest cost easiest to cut and shape and doesnt require overly specialized welding equipment or technique.
    For more specialized high strength/high performance application, the next step in materials is an alloy often called cro-mo or chrome moly 4130 dom which is stronger and therefore thinner wall sections can be used and result in lighter weight structures. Material cost is roughly 4 times that of mild steel as is labor for fabrication and welding as it is harder and generally involves tedious tig welding technique.
    Stainless is rarely used for anything more than "show" as it has inferior yield strength, costs about six times mild steel and is hard on cutting equipment and requires specialized welding.
    Also know that "stainless steel" can describe a broad range of alloys, strengths and finishes.

    And as I said, the question is far to vague to give a better answer. 11 gauge stainless may be extreme overkill, or exactly the material for the job.
    Dunno. I'd have to see a plan, design, something far more precise.
    And yeah, if you have to ask..... Maybe research a more appropriate source.

    1"/2" stainless...I'm going with "no" for all the reasons previously stated.

    never seen 1X for frames... 2x2 and 2x4, yes.
    I'd be pretty sure it would not work.

    Lol......

    It has to be stainless.....it cant rust ....ever....

    Cost is no object...

    Would a 1" 11ga work ?
    2" 11ga ?

    12ga ?

    Ok.....so a few votes for 2" 11ga

    And a few votes of....dont ask questions you dont already know the answer to...

    Anyone think 2" 11ga wouldnt work ?

    This is like crossing a street blindfolded. Might work, might not. You need professional advice from someone with knowledge of exactly what you are doing.

    What about 2" 12ga ? Would that clear the pickup truck/car hurdle without question ??

    This is just like the "what size wire do I need to use in my amp?" Answer: It depends. We need to know the voltage rating and current draw, and maybe even temperature rating. I can use an old wire coat hanger to hook up a speaker in a pinch, but it may not be ideal if I want things to look pretty.

    All depends on the plans drawn up and application. The material choice is just one part.

    2" square tubing for a pickup truck frame? Not even close. Look under a full size pick up truck. Now imagine replacing what you see with a 2" square piece of tubing. There's a reason the frames are so massive.

    If a 2" square pice of tubing would work for a pickup frame you wouldn't see the massive chunks of steel under current trucks. As for cars - who uses a frame under cars anymore? But looking at the "without question" part of you question the answer is still no. Even the hotrod guys use larger frame members under relatively low weight and often low powered cars.

    Now, if you're asking if a trellis structure could be built with 2x2 tubing to support a specifically designed vehicle then yeah, sure. But are you really going to design the entire vehicle around the availability of frame tubing?

    Any explanation why the frame can never rust, ever? 100 year old trucks are still driving around on their original steel frames.

    It would depend on the design, bracing and intended use. The question is posed as cagey with zero information and can’t be answered. Stainless takes special welding skills and has its own issues. Aluminum or steel would be a far better choice as well as following some tested design. If you do not know the strengths, weaknesses and limitations of the material you want to work with you are at an extreme disadvantage already.

    many early cars used wood frames of ash or oak.

    More info needed. No 2" square ss tubing is not near right for a pickup frame all by itself. Just figure it's the same strength as normal steel. Look under a pickup for size. Probably on the order of 3" x 6"

    Help me out here.
    Was my answer too long? Too technical? Unclear?

    Let me simplify. Based on the little information provided.

    No. Absolutely not.
