This is an aluminum threshold ramp with a patterned surface, also known as a ''checker plate'' or ''diamond plate''. It is used to provide smooth and safe access across small differences in height, such as doorways or thresholds.
Mobility Access: Its primary use is to facilitate the movement of wheelchair users, mobility scooters, or pedestrians using mobility aids, trolleys, or strollers to cross over elevated thresholds without obstruction.
