Hello, and thank you for your interest in Trex! Trex decking is not structural material and can not be used as joists. To properly support the Trex decking you will need to use structural material such as 2x8 or 2x10 (the size of your joists depends on the size of your deck). You can use the most cost effective option and use wooden joists, or you can use steel framing too. Thanks, - Trex Customer Care Team
