The chain link fence around our back yard is 21 years old and has not rusted yet. Chain link fencing comes in various grades. Normally, the big box stores only carry the residential grade, which is what we have around our back yard. Fence companies normally quote the residential grade unless you insist on a commercial grade. If you get competitive quotes, be sure everyone is quoting the same grade.

If children or pets may try to climb the chain link fence, you want to be sure the sharp points are at the ground.
