$600 for all of them or $40 a piece. The top panels look dirty but they are all wrapped in a protective plastic and have never been used I have 12x of both lengths. 24 total. They are 10ft and 12ft in lendth, and 3.5ft in depth/width . The panels overlap and I have mounting hardware and gasket tape for the overlapping sections that come with the panels. The panels are heavy duty and self supporting like the Quonset hut sheet metal. No rafters or additional supports needed. They could be used to make 2x 40ft long structures, or multiple smaller structures. I was going to use the 12 footers to build a RV carport and the 10 footers for another project, but I opted to build a ADU in my back yard and the city said the roof pitch needs to match my house. Hopefully you can put them to good use.
