    put a cup of motor oil inside the tube before finally closing them up. the heat of the welds should vaporise enough of it to coat the inside.
    for the outside, i like toolstations rustins primer. its got bad reviews, but you MUST thin it with XYLENE thinners and then its fine.

    He said roof tiles, presumably fixed to battens.

    Hi a bit more progress today i finished the tiling then cut the top row to suit,

    Then it was back to cutting and welding, first job was to put a block of timber in the ground to brace the floor on the 4mtr run, so i dug a trench then dropped the timber in,

    Then it was onto the cross beams i half lapped the center joints and butted the ends up and welded,

    I still need to brace to the timber to stop any bounce but i will do that before the floor goes down,

    A few pictures.

    You're taking all the strength out of the hollow section by doing it like that. Leave one of them alone and simply butt the others up against and weld. Probably going to be fine in your application how you've done it, but you could have saved a lot of time, trouble and slitting discs just doing it the usual way.

    I don't think it takes all the strength from it my initial question was regarding strength and was answered

    One reason it was done this way was because i am not a welder half butting is a fail safe way if the weld breaks the conservatory wont fall down, how ive half butted the joints the structure is self supporting,

    Total number of half buts was 10 taking 2 minutes for each section cut so ive wasted 20 minuets of my time something i have plenty of atm is time :-)

    Thanks for your input.

    It’s looking good, really coming on! Regarding the joints, that’s fair enough I can understand doing it like that if you don’t fully trust your own welding. It does look very ‘chippy’ though! :laughing:

    Thanks mate my welding improves every time i pick the gun up its probably ok but best safe than sorry,

    It was so easy doing it this way bolted the main beam to the wall and followed round one section at a time with a levelling leg on the end squared it up then welded no messing around with bricks trying to level it up and ive got the same result at the end of the day,

    All the box section will never be seen chippy or no chippy joints lol.
