7 Days to Die : crafting receipe question

If I look through the crafting tables … starts with ALL icon , followed by the other icons house/shirt/microscope I don’t see wood spike wall or the iron spike wall. If I enter spike in the search box then I can find them. I found a skill book for barb wire baracade but when I look through the crafting tables starting with all and going through each icon I just don’t find it.

so my question is : is the receipe/does the receipe show up when using the work bench ? I don’t have any benches or mixers yet.

thanks
