Double-Lock DL20


Double-Lock DL20 is a structural panel which is mechanically seamed during installation. The panel is an integral interlocking system by design which installs in one direction from a given starting point. A double male starter panel is available (for a minimal set-up fee) and may be installed in the middle of a roof area to achieve a symmetrical layout. DOUBLE-LOCK utilizes the traditional SMACNA standing seam “double-lock” plate.

Our Warranties are Second to None

DMI total system warranties protect "all aspects" of your metal envelope system. Whether that be the watertighness, the material or the finish. When looking at the warranties for your system it is important to note that not all warranties are created equal. Be sure to read the fine print to find out about any limits or exclusions. Are you truly getting a warranty or is it just a glorified maintenance agreement? Is the warranty covering all aspects of your Metal Envelope system? Is it guaranteeing that your project is being installed with the best quality? With DMI Total System Warranties you can feel confident that you are getting the best quality and guarantee in the industry!
