Ultra-high strength steel for high speed collisions

The Shape Corporation combine the best of two production methods - roll forming and pressing. The new light bumber is a breakthrough by using the properties of ultra-high strength steels. The new patented bumper to meets the automotive industry’s demand for lighter weight bumper systems that meet both performance and safety requirements.

“The advanced high strength steels we are using meet the demands imposed for withstanding high-speed collisions, and the more advanced the steel, the better the protection,” explains David Heatherington, Head of R&D at the Shape Corp. of Grand Haven, Michigan. “No other material would have enabled us to achieve our objectives.”

The pressed rear member is made of 1.4 mm thick cold-rolled advanced high strength steel with a tensile strength of 980 N/mm2. The front member is rollformed from 1.2 mm thick cold-rolled advanced high strength steel with a minimum tensile strength of 1300 N/mm2.
