they are made from a non-ferrous metal, this means theres no iron in them, and metals need iron to rust for example, steel will rust because its made from an iron mixture, whereas aluminium wont, because it has only aluminium in it, no iron.
Hi it's Chip. I hope you find all the information you need about homemade greenhouses because it really solved the problem I had. I wanted to protect my plants but fit into my budget. I haven't built a greenhouse before until now and it was easy. All I needed was the right info and designs.
