Fortress® Infinity I-Series Decking stands above the competition thanks to its revolutionary extrusion process. The co-extruded composite technology isn’t only stunningly realistic but also holds up in some of the harshest climates around the world. The Fortress® I-Series Decking's unique manufacturing process wraps every board with its exclusively engineered cap, which means your deck is substantially more protected than the industry standard. Two deck board packs each measuring 1 in. thick x 5.35 in wide x 8 ft. long and are of grooved design for interlocking installation. Fortress® Infinity deck boards are scratch, stain, mould, and fade resistant. They are also highly slip-resistant, making them the ideal choice for pools or wet areas. Backed by a 25-year warranty, further assuring trouble-free no maintenance long-lasting beauty.
