    going making two 12ft wide by 13ft high doors. they will be sliding. What size steel should I use to make them.
    4x2 for the frame and 2x2 for supports or would I get away with lighter?

    2*2 box, the 4*2 will only make it stupidly heavy and hard to move.

    id go lighter with 40mm box well braced 4by 2 would be madly excessive.

    Angle iron might even do for support. You will want one anyway a couple of foot from the bottom to make a runner to stop the bottom swinging out.
    2*2 is plenty big though.

    50mm x 2.5mm box

    More than adequate

    Like others have said 40mm box is plenty strong, don't forget to use angle on the bottom run or the middle run to use as a runner to stop the door kicking out in the bottom.
