Box Iron and Channel Iron Sheds

    I am going about building a few additional farm sheds. Approx 12ft high in front and 10 feet at the back. Lean to style, finishing down over an existing stone wall and cattle crush.
    I have a lot of 4" and 6" box iron and also strong 7x3 and 10x3 channel iron.

    I am wondering if these are strong enough to use instead if RSJs as uprights and cross members ? I can have each bay at a minimum of 12ft wide as I want to be able to reverse 10 ft mowers, trailers etc into bays when done.

    I also have 11 lengths of 305x305mm 15mm thick H iron beams... Too good to send for scrap but too heavy to use for these sheds.

    Has anybody something similar ?? Photos ? Design advice ?

    Wouldn't use the 10x3 as uprights as a good slap of a machine in the wrong direction would bent it over and I think the shed as a whole would be unstable

    A 10x3 channel is a fair beam of steel..

    Is it the shape/make up of them that would cause it to be unstable?

    8x4 H is about 23kg/meter

    7x3 channell is about 21kg/m

    And 10x3 would be about 28kg/m

    So youre not short of steel with 10x3, so is it the design/shape of the channel that wouldnt be suitable for a shed?

    You'd be supprised what is enough..
    Our small slatted shed was put up in 1974.
    Its a cavity wall construction but the uprights and the purlloins are 7*3 channel, obviously not galvanised as it wasn't done back then.

    Now, neither have gotten a belt of a machine - good drivers round these parts ;)

    Yeah I mean I hit an I beam one time with the loader. Whatever is the standard in a shed and you want to see the bend I put in it. Now imagine hitting the 10x3 at it's narrow end, I reckon it would bend like a leaf if struck hard
