These are heavy. They lend themselves to application using straight runs and mild curves, as they are hard to bend. They do come with 2 hole punched into 1 end of each 40" piece, so you can fasten them to each other using #12 3/4" screws and nuts. If you want to fasten them all to each other, you will ahve to drill holes at the other end as well. They do provide pegs/stakes made out of the same material whic will help to connect them.
