Why DOTs and Municipal Crews Count on DWS CastIron
For public works departments and transit agencies, failure is not an option. CastIron Plates are the go-to solution for regions where longevity is non-negotiable. Field crews trust the install method, procurement teams rely on the plate’s compliance record, and planners know they’re specifying a solution that meets AASHTO, ADA, and DOT standards and holds up year after year.
