Impacting automotive safety by reducing impact

The world’s first inner and outer door ring system reduces cabin impact

Utilizing nine total gauges of its patented press hardenable steel, ArcelorMittal, in collaboration with Honda R&D Americas and Magna International, created a hot-stamped, laser-welded inner and outer front door ring system for the 2019 Acura RDX. This lightweight door ring offers unprecedented safety, and its hardware earns hardware. It garnered a fivestar rating for the narrow offset crash test and helped the RDX become an IIHS Top Safety Pick+. Additionally, the dual door ring is a finalist for the 2019 Automotive News PACE Award.
