Step 2: Assemble rear wall panels.
You will find it easier to assemble your shed using sawhorses with timber studs attached ( timber
needs to be the same length as the shed ( 1.5 M ) or alternatively, a trestle table.
Place 6R and 6L the sheeting on your work table and join together with the self tapping screws
per the diagram.
Now fit 20B top channel and 20C bottom channel to the sheeting by tapping it in (diagram A)
or sliding it in. (diagram B) Note that the small lip of the channel is always facing out. This is to
ensure that rain water can not build up inside your shed.
