We are having a steel frame balcony constructed and want to cover it in wooden decking. The frame is made from T section steelwork and these would provide an open span of 870mm for the deck boards.
I looked on the TRADA web-site http://www.trada.co.uk/techinfo/asset/send/929/content/TDeckbook/DeckTabA1-link.jpg about maximum spans for deck boards and they all stop at 600 mm - a deck board of 75x38 is treated just as strong as 150x38.
I am guessing that the table stops at 600 as this is the maximum standard joist spacing for floors, but that 150x38 could span larger gaps.
Has anyone any experience or advice about spanning larger distances ?
