Lean to with corrugated PVC sheet

[unhing3d]

Hi,

I am planning on building a lean to on the back of my garage 2300mm x 2400mm with a slope of 10 degrees.

I'd like some help with what timber I need to buy for the outer construction and then for the purlins.

It has to be strong enough to support the corrugated PVC sheet and a heavy snow fall please.

I'd also like some help with the number of and the spacings for the purlins please.

The sheet comes with the following specs, Height: 0.08cm Width: 66cm Length: 2.4m Weight: 1.88kg.

Thanks in advance for your help.

Joe

I would use 4x2" at approx 18" centres for rafters and a bundle of 2x1" batons spaced evenly to fix the sheets to.
