Vinyl fence offers lifetime durability for a full privacy fence. It requires some maintenance, but the maintenance is more than a good trade-off for not having to ever replace the fence. It's available in three levels of quality, which your sales representative will be more than happy to explain to you.
Aluminum fence is the modern alternative to chain-link or wrought iron. Its lightweight and simple design causes it to cost less to install than wrought iron, and its look makes it nicer to look at than chain-link. Like wrought iron and chain-link, it's also a lifetime product, making it a great alternative.
