Curved Snap-On-Seam

Curved Snap-On-Seam CR-SS10 is a non-structural curved snap-on-seam system. The system is designed with two components: the panel and the seam cover. CURVED SNAP-ON-SEAM is a non-directional panel system allowing installers more control during installation over seam layout and symmetry of the panel area.

Our Warranties are Second to None

DMI total system warranties protect all aspects of your metal envelope system, whether that be the watertightness of the roof or siding, the Galvalume ® steel, or the durable PVDF KYNAR® finish. When looking at warranties for your system, it is important to note that not all warranties are created equal. DMI warranties ensure the watertightness of all flashing conditions, trims, curbs, valleys, and penetrations. Building owners are protected with a total system warranty - “from the deck up” when using DMI insulation, fasteners, and underlayment. Our warranties are backed-up by a full-service Engineering Department, generating project specific shop drawings. Quality control is monitored by a minimum of two on-site inspections by our Field Technical Inspectors. DMI Total System Warranties give building owners and design professionals confidence that they are receiving the highest quality and most complete warranty available in the industry.
