the aluminum profiles move between the surface-mount support plates to take thermal movement, minimal seismic movement and some vertical deflection, while rubber gaskets between them stop metal-to-metal noise.
the optional water barrier below the of-1670 carries water away along the joint, so the structure below stays dry as the joint moves.
built for heavy loads and slow-moving vehicles in warehouses and parking garages, the of-1670 is rated 35 kn in the system drawings.
this video demonstrates the assembly process, perfectly designed for easy installation for durability and reliability.
The surface-mount aluminum profile sits over the finished floor with a clean, continuous line, and the EPDM insert keeps liquids and dirt out of the joint.
