    Default G'day! great forum. done some research and need someone in the know.

    G’day Folks,
    Let me just start by saying that this forum is excellent! I have already learnt a bit just by reading other peoples’ questions and answers and am now keen to do all sorts of home renovations. I’m sure I will have many questions in the future.
    Right now I am after help regarding rafter and beam sizes for a skillion fly roof over my deck.
    The area of the deck which I plan to roof runs 6500mm along the house and 5500 span. I plan on just colourbond (or similar) roof sheets and no insulation as the roof is going to be high enough. The rafters will be attached to a beam & roof-extenda bracket arrangement on the higher side.
    What research I have done leads me to believe that I will need to use H17 275 X 50 rafters with 900mm centres.
    Is this correct? Is there better/more cost effective alternatives? Also, I cant seem to figure out what dimensions the beam on the roof-extenda brackets and posts should be or how many roof-extenda brackets I need...
    Sorry for being such a noob and no doubt not using all the right terminology.
    If anyone can help it would be greatly appreciated!
    If I need to provide more info to have these noob questions answered let me know.

    Welcome...you don't know what you have started lol

    re-post your question in another thread as it might not get the attention you seek in the welcome pages.

    Good luck

    edit: tried adding a link that didnt work.


    Google Panel tech or thermaspan for a different option.

    There are a heap of other similar products out there as well. Probably be comparable with timber in price but easier/lighter to install IMO.

    Thanks for that 2X4.

    I checked out paneltech and thermaspan.

    They are probably better products but I've got my heart set on the tin (colourbond) roof and big wooden beams all nicely oiled....

    Is anyone able to verify if the H17 in 275 X 50 is what I need for a 5500 span?

    Yes. That size will span 5.5mtrs according to Hyne span tables.

    No cieling sheets, light tin roof and spacings at 600 and you could drop a couple of sizes.


    Design in Hynev5.1 is a free dowload and is a handy tool. Once downloaded be patient, no need to register, and will grant you access with limited useability.........which is still alot.

    2X4, thanks man. I just wanted to be sure that i was reading it right..

    Over a 5500 span will there be any problems with bowing in the rafters?
