Chain link fencing is extremely popular for several good reasons: they're easy to build, last a long time with little maintenance, and the materials needed to make them are readily available and very affordable.
Generally, they're preferred for applications in which an unobstructed view is desirable, or when cost is the most important consideration. Chain link fences are among the least expensive options on the market (unlike wrought iron fences, which can be quite expensive). They're a fixture at baseball diamonds, in parks and around school grounds and athletic facilities, but for homeowners, they're most commonly chosen when it's necessary for a parent or pet owner to keep an eye on their charges from a distance.
If you want the affordability of chain link fencing with enhanced privacy, chain link fence aluminum privacy slats may be the answer. These privacy slats are simply inserted into the chain link meshing, shading the fence's transparency. Chain link fence aluminum privacy slats are also quite affordable and won't raise your bottom-line cost very much.
To deter animals from trying to dig their way beneath the fence, chain link dog fences add a secure wire along the bottom. These make it virtually impossible for dogs to dig a hole deep enough to climb underneath or push their way through the bottom of the fence.
You can also add coils of barbed wire along the top of the fencing if you want the utmost in protection. However, this will also have the effect of making your home somewhat uninviting, so you have to weigh this against the added protection you'll get.
You can erect your own chain link fencing within the space of a day or two, depending on the complexity of the design and how you choose to set the fence posts. The first step is to mark the outline of the fence on the ground, using strings, and determine the positions of the posts. The posts should be spaced evenly and positioned so that any necessary turns can be executed at a perfect 90-degree angle.
You'll also need to mark your end posts by driving stakes into the ground at the positions they'll occupy. Once you've done this and established your right-angled corners, you'll dig the holes for the posts and set them. After a day or two, once the concrete used to set the posts has had a chance to dry, you'll add the top rails, stretch the chain link fencing into place, fasten it to the top rails, and install any gates you've left room for.
In case you want something with a different look than the standard silver finish, you can usually buy chain link fencing supplies in glossy or matte black, or you can customize the color by painting it yourself. Either way, you'll get a secure perimeter barrier for an affordable price.
