steel shed

[kia cat]

We have an all steel bolt together shed like this one
[ http://www.shedbaron....sp?ProdID=2&ImageNo=1 ] it's sitting on concrete paving slabs, problem is the guttering or lack of. The supplied gutter is more of a thin gully to neaten up the bottom edge of the ridged sheeting. It blocks easily and the water runs off all the way along.

If I want to add conventional guttering either side, am I best off screwing a wooden strip inside and out, to fix the gutter to ? or is there any easier way around this? Thanks all

It all depends on how much overhang you have, Kia. If there's say, 2" (50mm), then fix ordinary plastic gutter brackets to the two sides of the shed. Perhaps use "pop rivets" so that there are no sharp points sticking out inside.
You only need a fascia board if the overhang is so large that you need to bring the gutter out from the shed.
uPVC fascia would save you having to keep painting it.
