portfolio and our channel partnerships position us well to capture a meaningful share of that business over time.
Ultimately, these actions are about building a distribution network that is simpler, faster and more effective, enabling us to execute our strategy and achieve our long-term financial goals. Another decisive step we are taking, which I'm pleased to announce, is the acceleration of the decking production at our Little Rock manufacturing facility.
Little Rock is strategically located near key raw material sources, large residential markets like Texas, a strong pool of skilled labor and a major transportation hub, which will help optimize freight costs for the customers in the Central U.S. who are currently being serviced by our existing facilities in Virginia and Nevada.
Equally important, this location positions us closer to several key growth markets for wood conversion, particularly in the Southern Sunbelt. The Sunbelt region remains heavily weighted towards wood decking, specifically pressure-treated Southern Yellow Pine, representing a significant conversion opportunity for Trex. Given these factors, Little Rock is poised to become our wood conversion growth engine. Together with this decking capacity expansion, we have been actively investing in our wood conversion strategy through refreshed branding and marketing initiatives.
These efforts are already gaining traction with our Trex Enhance® Basic decking products - our primary driver towards wood conversion - also delivering strong sales during the quarter. The opportunity remains substantial. Wood continues to represent almost 75% of the decking category with Southern Yellow Pine accounting for the majority of the wood decking sales. As a reminder, every 1% share we take from wood represents about $80 million of incremental sales opportunity for Trex.
With the performance attributes of Trex Enhance® product line, we believe that we have one of the best solutions in the market to accelerate this conversion opportunity, and we will not stop there. We will continue leveraging our world-class materials science capabilities to develop innovative, high-performing and more cost-effective products that further expand the opportunity ahead.
I'll now turn it over to Prith, who will provide you more detail on the quarter and our outlook. Prith?

Thank you, Adam, and good morning, everyone. Unless otherwise noted, all comparisons are on a year-over-year basis.
Second quarter net sales of $418 million came in well above our expectations, growing 8%. Importantly, Q2 sell-out was slightly ahead of sell-in, reflecting strong underlying demand and healthy consumer engagement across our channels. On a rolling 12-month basis, sell-in and sell-out grew 9% and 7%, respectively, compared with 7% and 6% in the first quarter.
The difference primarily reflects timing effects within the trailing 12-month period rather than any meaningful divergence in underlying demand trends. As Adam mentioned, our sales growth this quarter was broad-based as we experienced strength across product lines, distributors and price points. Railing sales returned to double-digit growth, while we also saw a nice increase in Trex Enhance® Basic sales, the first meaningful sales increase we've seen at this price point in
