Step 3: Assemble side wall panels
Place 2R’ and 7R the sheeting on your work table and tap or slide in 25 top channel and 20A
bottom channel. Fix and position the 31 mid wall channel using the self tapping screws. Fix 20A
the bottom channel by the self tapping screws but not 25 the top channel in this stage. 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. Repeat the same steps for 2L’ and 7L’ the other side wall.
