AC2® pressure-treated thick pine decking offers many advantages over 5/4 standard 1-inch treated decking. AC2® brand treated wood products use MicroPro® technology, which is a revolutionary way to pressure-treat wood for decks, fences, landscaping, and general construction uses. MicroPro® technology offers many benefits, including significantly improved corrosion performance, a lighter, more natural color, and it is environmentally friendly. Wood is a natural product with many unique characteristics and properties. While wood's strength and workability make it highly suited for general construction and building projects, other inherent characteristics make it subject to checks, splits, warps, and twists.
