Aluminum decks are gaining in popularity, because they will not rost, rust, warp, splinter or crack.  They are also extremely weather-resistant.  The powder-coated finish on the aluminum planks last virtually forever.  Aluminum decking is non flammable, will not attract wood-boring bugs and is cryogenically strong (will not get brittle in extremely cold weather).  Aluminum is 3-4 times lighter than wood, composite or plastic lumber but yet it is 2-3 times stronger.

Pros of Aluminum Decking:

• 2-3 times stronger than other decking materials
• Planks can be cut with same saws and carbide-tipped blades used to cut wood
• Gap-free and watertight
  • Self-draining channels collect and dispose of rainwater
  • Space below deck stays dry
