ML200

Union's ML200 panel is a mechanically seamed standing seam roof system that can be used for structural or architectural applications. The mechanically seamed standing seam system panel is secured with concealed clips and the standing seam panel side laps are locked together using a rooftop seaming machine. This type of standing seam roof system provides very high wind uplift resistance and structural integrity. ML200 standing seam system can be specified as an accent feature or a total roof system for schools, shopping centers, banks, hotels, offices, and a variety of other applications.
