The ML-150 Mechanical Lock (1.5” High standing seam) features structural performance as well as architectural aesthetics. ML-150 Panels can be factory formed and/or fabricated, for all substrates, at project locations. Utilizes concealed fasteners with a fixed and/or floating clip system. The floating clip system reduces the effects of thermal stresses on the panels helping to maintain a beautifully smooth, and uniform appearance, despite fluctuations in temperature. ML-150 Mechanical Lock Panel is a mechanically seamed, vertical leg, standing seam roof system that combines a 1.5-inch tall slim rib with exceptional uplift resistance. ML-150 Panels are designed to withstand the most rigorous weather conditions. The ML-150 Panel is available in a 16-inch width and allows for the installation directly over purlins and bar joists.
