AridDek is a precision extruded marine grade aluminum decking product. The proprietary tongue in groove design creates a seamless, interlocking surface with an integrated gutter system to create a 100% waterproof deck/roof structure. AridDek is suitable for long term exposure to heavy sun and salt environments and it provides maximum heat dissipation to ensure a cool-to-the-touch surface, even on hot summer days. It is impervious to insects and the non-porous surface resists mildew and bacteria. AridDek's skid resistant finish requires no sealing or staining and will not splinter, rot, or decay. Strength tested to 400 PSI on 24 centers, the no maintenance waterproof shield is ideal for main and upper deck applications.
