Corra-Lok is a concealed fastener corrugated metal panel. Finally, there is a panel with the beauty of a corrugated line without the exposed fasteners! Corra-Lok panels have a positive panel-to-panel interlock and can be combined with Metafor and the Multi-Purpose system for the ability to create interesting patterns and breaks. The fasteners are hidden by the consecutive panel.
