Trex's new Spiral Stairs collection is designed to enhance the beauty of any backyard, while also providing a functional, space-saving alternative to standard stairs. Offered in both aluminum and galvanized steel, the system is modeled to suit the tastes - and budgets - of any homeowner. Engineered to fit seamlessly with pre-existing Trex decking and railing systems, the new stair line showcases exclusive options including a lip-up tread design to ensure the space between risers doesn't exceed four inches. It's also compatible with various components of Trex's LED-dimmable Trex DeckLighting system. With 12 different customizable options, the understated, contemporary design of Trex Spiral Stairs makes a strong fit for private residences, multi-family housing and commercial settings, while meeting strict code requirements.
