the interlocking aluminum profiles take horizontal thermal movement and settlement of ±25% of the joint width, plus some vertical movement, and neither profile can lift under wheel load.
the optional water barrier below the of-1685 carries water away along the joint, so the structure below stays dry as the joint moves.
rated 35 kn in the system drawings for heavy pedestrian and vehicular traffic, the of-1685 suits heavy loads and slow-moving vehicles in warehouses and parking garages.
this video demonstrates the assembly process, perfectly designed for easy installation for durability and reliability.
The low 19 mm interlocking profile sits over the finished floor with a neat metal line, and rubber gaskets between the plates cancel metal-to-metal noise and keep liquids out.
