Threshold Plates are generally Aluminium extrusions that are fitted to the sill under doors providing a clean delineation between adjacent floor surfaces.
A weather barrier in themselves, threshold plates provide an optimum sealing surface for door bottom seals. Being hard wearing, threshold plates offer an elevated sealing plane which, in the case of sweep seals, prevents contact or excessive resistance over carpeted, uneven or sloping floors.
Threshold Plates have been designed to withstand the day to day rigours of heavy pedestrian and wheeled traffic encountered in commercial buildings. The low profiles do not impede wheeled traffic nor do they present any tripping hazard to pedestrian traffic.
