    I am going to make a 16ft gate for a field, the outside frame is going to be 40mm box and the bars across the middle are going to be maybe 30 x 6mm flat bars. Would they be strong enough or would I be better using 30mm box for the bars in the middle. There is going to be just the one bar down the middle and it is going to be 40 x 6mm flat bar

    Something similar to this

    Think I'd be using box iron for the cross bars, modern flat 6 or 8 mm is very flexible compared to the old stuff and won't do much for the strength of the gate. Are you going to roll flat iron into an arc like the photo too?

    If you want gates for cattle you would need 50mm box all round. A gate of your strength would be wobbly. I made a few 10ftx5ft gates for pens lately from 16mm rebar. I was happy that they were economical and will not rot out, as they are not hollow to hold water. If you are going to the bother of making a gate, might as well make it solid. Some old forge gates are several hundred years old, although they used wrought iron which was not as susceptable to rust. the forge gates failed when the rivets rusted off, modern welds are superior in longevity imo.

    I agree, or go with a heavy duty gate from your local hardware outlet.
    The gate above would be all over the place

    For 16ft gate you’d have to go with 50 x 50 x 3 box to give the gate more strength . Internals you’d want the same bar running vertically in the middle of the gate . Once the frame is strong internals aren’t important unless your applying pressure to them (like loading cattle against them ) After that you’d get away with 30 x6 flat bars running horizontally on the gate . The arch bar in the gate in your pic adds strength to the gate . You can do similar with 30 x 6 flat going at an angle from the corners to the center . Get it dipped and you’ll have a gate that’ll be there longer than any coop gate and will be more appealing to look at .

    This is a bought job. We have it at an entrance to the farmyard. I think it was made by Gibney's of Oldcastle.
    It's a good strong gate and not overly heavy.
    14 feet ,all made from box.
    The perimeter is 40 x 40 . The intermediate rungs are 30 x 30.
    The hoops 40 x 5 flat.

    These are a pair that the brother made for the entrance to his house. Motorised, galvanized and painted.

    Up until last year I had a 19' gate made out of 40mm box and the horizontals were 25mm box,I joked it was a family heirloom as it was made the same year as I was born,I still have a 15' gate made at the same time.

    Is the top rung just angle on that @mixed fleet or did he find somewhere selling the proper ‘T’ section lengths?
    None of the steel suppliers locally know where to get it! But I see new gates made with it so it’s available somewhere

    This ten foot gate was the yard gate here in my grandmother's time she would have spent her lifetime painting it annually. I remember that there was nearly a half inch layer of paint hanging off it and and my father decided to throw it into a bonfire to burn the paint off it. It was amazing that the gate didnt warp from the heat. I'd say it's over a hundred years old as my great grandfather built the pier and hung that gate and he died in 1924.

    I was going to get it rolled but I might get it cut out with the plasma. It depends which works out the cheapest

    The gate will be near the house so I don't want to use the ordinary gate

    Beautiful job there, mixed fleet, You'd struggle to think It was two gates!

    Are The hoops done In certain parts of the country? Never seen that around here, Always lengths of flat bar to strengthen It.

    I have 8ft and 9ft versions of theese mostly without the hoop .
    Never saw a 10ft one.
    It might be a bit newer than mine

    Same as that, 8' and 9' are common enough. They don't usually have the Hoops like @Peter s gate. It must be a newer or English touch. @nashmach

    This Would Be more like the ones down here:
    20190316_102352.jpg

    This gate was removed from a field here to the yard about 8 years ago. My father never remembers It anywhere else so It probably predates our time on this farm.

    Think It's a 10ft gate.

    Does anybody have a real old timber field gate or indeed The early steel gates where the uprights were made from timber And bars were made from steel?

    There's a few of those lingering around here but All retired now!

    I’ve never seen one that’s a mix of wood and steel?
