9: How well does it hold up in very hot and cold climates?

Nextdeck® decking is one of the most durable decking products available. Because of the aluminum construction, it is able to withstand extreme heat and cold. Aluminum has a working temperature of -400 to 400 degrees F. It is completely fire proof and has a melting point over 1200 degrees. Nextdeck® aluminum decks will not freeze and crack because aluminum does not absorb water. They also have very low expansion and contraction characteristics because of the lack of water absorption.
