Rivets seem secure, size is as advertised, wall material seems as heavy as original walls. Solar protection coating to be judged in 2023 or 2024 !I added ratchet straps inside enclosure to each quadrant. (Strap (only) touching roof) these appear to be well worth the money BUT only time will tell us the whole truth!!!!Overall, I am very pleased with this purchase.
