Trex Golden Hour Composite Decking 16ft Grooved

When the goal is a pristine, high-end outdoor space, surface fasteners simply get in the way. At National Decking, we supply the Trex Golden Hour Composite Decking 16ft Grooved to contractors and homeowners who demand perfection in their build.

The sides of these boards feature a precision-machined channel designed exclusively for hidden fastener systems (such as the Trex Hideaway® clips). Instead of drilling screws through the top of the board, the clips slide into the groove and fasten directly to the joist. This secures the board invisibly, resulting in a perfectly smooth surface that looks and feels like premium interior hardwood flooring. The 16-foot length is highly favored as it spans most standard deck depths completely, eliminating the need for splicing boards together.

Premium Performance Delivered

Trex Enhance® Naturals provides the perfect intersection of authentic wood aesthetics and cutting-edge material science.

• SunComfortable™ Heat-Mitigation: To ensure your deck remains a comfortable gathering space, the Golden Hour colorway utilizes advanced solar-reflective technology. It absorbs significantly less heat than older, dark composite generations, staying cooler to the touch during the peak of summer.
• Lightweight Scalloped Profile: Turn the board over and you will see a scalloped (ridged) bottom. This engineered profile reduces the board’s overall weight, making a 16-foot length much easier to carry and position without sacrificing structural strength.
• Eco-Friendly Engineering: Made in the USA, Trex decking consists of 95% recycled materials, including reclaimed industrial sawdust and recycled plastic film.

National Decking Pro-Tip: For the most efficient installation of your 16ft grooved boards, we highly recommend using the Trex Hideaway® Universal Hidden Fasteners. These clips not only hide the screws but also automatically space your boards with the perfect 1/4-inch gap for optimal drainage and thermal expansion. Remember to use Solid (square-edge) boards for your outer perimeter “picture frame” to hide the grooves from the yard’s view.

Frequently Asked Questions

Can I use screws through the top of a Trex Golden Hour Composite Decking 16ft Grooved board?

While it is technically possible to face-screw a grooved board, it defeats the purpose of the grooved design and can look unsightly. If you prefer to face-screw your deck, or if you are installing the outer perimeter border where the side of the board will be visible, you should purchase the Solid (Square-Edge) version of this board.

How many hidden fasteners do I need for a Trex Golden Hour Composite Decking 16ft Grooved?

Hidden fasteners are installed at every joist intersection. For standard residential framing with joists spaced 16 inches on center, you will need approximately 13 hidden fastener clips per 16-foot board (one per side at each joist).

Does the scalloped bottom make the board weaker?

No. The scalloped profile is structurally engineered to maintain the same span rating as a solid-bottom board. It is fully approved for standard 16-inch on-center joist spacing for perpendicular installations and will not sag or bow when installed correctly.
