KLIP-LOK CLASSIC® 700 features improved rib strength for excellent spanning capacity. Visually, a strong rib makes a bold statement rising from flat pans with longitudinal fluting. Clips permit thermal expansion of long, straight runs, and because there are no piercings through the cladding; the long, straight lines of LYSAGHT KLIP-LOK CLASSIC® 700 remain crisp and clean. And no piercings means superb weatherproof performance.
