Hold on a sec. Are we asking about guttering, bubble wrap or shelving? Attaching bubble wrap. Garden centres sell plastic whatsits for the very purpose. Shelving. They will also sell tiny right angled brackets and special alloy nuts & bolts. I've just fitted a wooden shelf in the greenhouse. 5" wide wood. I made short length of copper brackets made from old water pipe with alloy nuts & bolts and a screw at each end. Easy DIY job.
Copper and Aluminium are electrochemically not compatible. I.e. the aluminium will corrode quickly in contact with copper. Not a good idea. Otherwise I agree with you. Just use aluminium alloy for the brackets where possible, or insulate the metals from each other with plastic, or possibly paint the copper to minimise metallic contact between the two.
Bit confused-but are there any wooden battens inside the top of the shed you can screw into from the outside?
How strong is this plastic- will a screw hold?
Thanks.
