Drop & Lock panel attachment systems enable designers to develop any surface into a panel system with cold connections and no sealants or adhesives. The surface options include not only metal panels, but also glass, ceramic and other finished surfaces. This flexibility makes Drop & Lock one of the best options for developing dry systems for architecture.

All of the systems offered by Zahner are dry systems, meaning that no sealants are used. This is an important distinction, because systems which use sealants and glues will have shorter lifecycles. Sealants have a tendency to "bleed" onto adjacent surfaces, causing dark stains and streaking across the material. Using a dry system will help with both longevity as well as aesthetics. 

Drop & Lock systems benefit from the technologies developed in the Zahner-owned Inverted Seam patent. The systems use a two-part process for installation, and include all of the hardware needed to hang the panel system. Use of Drop & Lock systems eliminate the need for structural steel in some cases.

Components of Drop & Lock Systems

Each system is composed of both female hardware and male hardware which enable fast connections with no need for additional sealants or fastening systems. The female components provide the vertical ribbing, attached to the structural steel. The male components are built into the panel. Hanging the panels is a rapid process. Construction teams lift the panels into place, insert into female connections, and drop into place.
