I believe the siding is to be 29 gauge metal. The building contractor has informed us that it would be delivered to the site, all we are to do is install the panels and trims. I "assume" (I know, I know) that it will be delivered by the siding supplier and unloaded with a fork lift. That part may not be a issue. It's the lifting of one panel that will be up to twenty feet in length and placing it. Is there a method such as sliding the panel against the wall while lifting, ... or use of some backing material to keep it ridgid until it is placed? Hope this is clearer.
