Our DMC 150SS roof system will lend striking dimension to any architectural design. This versatile 1-1/2″ mechanically seamed panel can be curved to a wide range of radiuses and applications – from barrel roofs to conical shapes and more. Concealed fasteners and a floating clip system reduce the effect of thermal stresses on the panels, helping to maintain a beautifully smooth, uniform appearance despite fluctuations in temperature.
