Because of the weight of our packages, there may be some panels bent in transit if UPS/Fedex handle it in a rough way. No worries, you can fix this easily so your gardening isn't delayed. Our panels are manufactured through a bending process from flat steel coils, in other words, they were bent before. It will not affect the corrosion resistance to bend them back. It may be hard to bend all the panels at one time, but you can always bend them back one by one. Here is an instructional video you may find helpful: https://youtu.be/lh3PWhQsFGI
