Aluminum does not contain iron, nor does it absorb water. It will not rust, rot or crack, and is impervious to termites and other pest infestation. While decks, railings and fences made of traditional products require regular scraping, sanding, painting & sealing, aluminum maintains its color and appearance for a lifetime. You do not need any special cleansers, or any sealants or stains to maintain the beauty of your outdoor space. UV-resistant aluminum also provides a cooler surface for your outdoor living space. Aluminum decking, railing and fencing products are truly maintenance-free, giving you the gift of carefree time in your outdoor space.
