Timber sizes

[paulpa]

Is there a table to work out timber sizes for a mono pitch roof base on span?
In my case 1.7m span
Googling i find
http://www.bsw.co.uk/uploads/files/bsw_timber_c16_span_leaflet_a4_4pp240810.pdf
So at 400 centres would
45 x 95mm $x" be ok?


AHH wrong table "The span tables in this document have been prepared to assist in the preliminary design of timber decks"

They'll do, all the tables here and there are based on the Trada ones anyway.
