Looking to build a deck? You'll first need to know which type of material you need.
Aluminum
The alpha when it comes to resistant - it won't rust, warp, crack; it's mold and slip-resistant. It won't catch fire, bugs won't ruin it, and it won't get brittle in the cold. Also it won't get too hot in the sun. All these benefits come with a price - at $9-11 per linear foot it will definitely be an investment, but you'll never have to do maintenance.
Cedar
At $2-4 per linear foot, this material is a more common choice. It's naturally resistant to rot. decay, and voracious insect damage. However because it's wood, you'll have to power wash it every year, and a new coat of finish every three to four years.
Tropical Hardwood (Tiger Wood)
According to East Teak, Tiger wood is extremely durable, easy to work with, highly resistant to moisture absorption, white & brown-rot organisms. About the same price as cedar (Between $2-4 per linear foot), but a little more durable and you get that genuine exotic look.
Composite Decking
A great material for it's price - Between $2-4 per linear foot, it's a fine choice for decking material. They require little maintenance; you just need to check for mold in shady areas. Plastic decks won't need this, but composites will need a new finish from time to time to keep from fading.
PT Deck
Pressure treated lumber - the most common decking material. For about $1 per linear foot, it's popularity is no surprise. It is prone to cracks, splinters, and warping, and will need to be washed annually and stained every 2-3 years. If price is the influential factor, than a PT deck may be your sole option.
