hi, quick question, if i use 2x4 which are 5mts long for my shed roof, can i use mini joist hangers to attach them? i will be using 18mm osb3 sheets on top covered in felt(flat roof). ive purchased 47mm x 67mm mini joist hangers from toolstation but they were unable to give any advice and i dont want the weight of the osb to make them give way overtime. thanks

if the span of your roof exceeds 2.5m you will need to increase the thickness of the timber or brace the timber

Any idea of how I can brace them as the timber has already been delivered. :-(
