The DMC 175S is distinctive for its broad width seam, impressive structural capabilities, and easy Snap Lock installation. Featuring a 1-3/4″ seam height, this continuous interlocking engineered roof system has a concealed fastener and clip application that allows thermal movement and requires no mechanical seaming to ensure weathertight integrity. The installation is simple and quick, yet it withstands extremely high design pressures and is approved for use on Weather Tightness Warranty projects.
