In 1984, Ironsmith was the first tree grate manufacturer to produce a 1/4″ slot opening width tree grate. Ironsmith developed the starburst series 1 and series 2 in response to requests from Las Vegas hotels for a grate that would not trap spike high heel shoes. Five years later, the Americans with Disabilities Act was passed and Ironsmith removed all grates with slots over 1/2″ from its product line to promote improved safety for all pedestrians.
