Under Deck Systems
An under deck system is specifically what it says. It is installed to the underside of the floor joists. It is typically a thin aluminum that provides you with choices of color and design. If you are planning to build a new deck, then we highly recommended you use a product that is a drainage structural aluminum system mounted to the top of the floor joist and then the deck boards are mounted to the top of the structural aluminum drainage system. The major advantage is that you can do electrical, plumbing gas lines and a nice ceiling effect for the drive patio below the deck. It also allows you to observe any movement. There are structural changes that take place with the deck. Whereas if you use an under deck system you will not be able to see any changes in the structure.
