I just recently installed a new fence, although not made of metal material. But I still know what materials you need – for example 6×8 metal fence panels. You can find them on the Global Source website, they have very cool prices. I know this from my own experience since many stores deal in exactly this kind of material.
I recently went through the process of installing a new fence myself, so your post really caught my attention. Even though I didn’t use metal panels, I looked into options like 6×8 designs. It’s interesting how certain metals, like Tantalum in other industries, are valued for durability just like we look for in fencing materials.
