An aluminum fence doesn't necessarily mean a standard hurricane or chain link fence, but can refer to the style of vertical bars that resemble wrought iron. If you're thinking of getting a new fence for your property, you might note some advantages of aluminum versus any other material.
Rust and corrosion resistant
Aluminum by its nature doesn't rust or corrode. This makes is a good choice for a fence that might be located near a pool and which gets constant water splashing, and for fences in tropical areas or those with high humidity. You will need to perform far less maintenance on an aluminum fence in those areas than wood, steel, and other such materials that are prone to rot, corrosion, and the like.
An aluminum fence with vertical bars doesn't provide much of a toehold for anyone to climb. Pointed finials at the top can also be a deterrent to intruders. However, a person might easily chip away at a wood fence and then use those chipped areas for climbing, or more readily pull slats of wood fences away from their connectors to enter your property. If you opt for a short vinyl fence so your property doesn't look so closed-in, this too can be easy to scale. An aluminum fence with bars keeps your property open but makes it difficult for someone to get inside.
You typically cannot paint a vinyl fence, so you're simply stuck with its look over time. An aluminum fence can be powder coated virtually any color, so you can update your property's look by going from black to white to slate grey, and so forth, when you want a new look for your fence. While you can also paint a wood fence, this can be a huge undertaking and especially if you want to paint both sides. A powder coating company can quickly and easily have your aluminum fence coated to a new color, saving you time and hassle.
If you want a gate to the driveway attached to your fence, the lighter weight of aluminum can mean less stress on the hinges and opening mechanisms. This can translate to less damage and less maintenance of that gate, versus a heavy wood or steel gate. You may see that you need to replace the hinges or springs less often with a lightweight aluminum gate and that it continues to operate properly over time, as it won't have extra weight giving resistance to the springs and hinges every time the gate opens and closes.
