The Trex Deck Railing Designer supports the configuration of more than 2,000 railing combinations from Trex’s portfolio of 13 railing lines. Built with advanced 3D web technology, it loads instantly on desktops, tablets and mobile devices, giving users access to the tool in any setting. Its features include:
Dual Mode Interface
“Explorer Mode” is a starting point that allows users to review and compare Trex railing styles and materials through a gallery of images. They can also compare warranties and pricing.
“Expert Mode” takes users who know what they want straight to the configurator, where they can customize railing selections and calculate materials.
Real-Time 3D Configuration and Material List
Users can visualize railing systems in 3D and obtain a detailed material list in as little as one minute – a process that previously took 10-20 minutes.

Mobile-Friendly and Field-Ready
Optimized for fast, responsive performance on any device, the tool is ideal for those on the job and on the go.
Save and Share Features
Users can save configurations via curated links and share designs on social media platforms like Facebook and Pinterest, making collaboration easier and more efficient.
“This is not just a design tool; it’s a highly focused, purpose-built platform designed to simplify the planning process for both contractors and homeowners,” noted Lee. “It helps with project specification, supports retailer associates at point of sale and gives homeowners a clearer path to the right railing solution for their outdoor space.”
