Mechanical Lock Panel System

Concealed Fastener Roofing & Facade Panel

The Mechanical Lock panel system is a performance based mechanically seamed panel system designed for architecturally demanding projects. Adaptable to many physically demanding environments, and ideal for softer metals like copper or zinc, Mechanical Lock is a favorite in commercial and residential projects alike.

Available in 1" and 1.5" rib heights, this panel system can be ran to length creating a seamless line from ridge to eave in roofing applications.  Able to be ran in a wide range of finish coverages, Mechanical Lock can also be used in a variegated pattern on wall systems for a modern look.

For additional performance and structural needs, Bridger Steel also offers a 2" Structural Mechanical Lock for extreme performance requirements.
