The use of high-strength steels (HSS) and ultrahigh-strength steels (UHSS) has made stamping complex structural automotive components increasingly difficult and capital-intensive. Changing from traditional stamping (at room temperature on a mechanical press) to hot stamping (at elevated temperatures on a hydraulic press, with a water-cooled die for quenching) provides a suitable alternative for OEMs that produce these challenging parts.

Roll forming of roofing components for the pre-engineered building and component industries presents unique challenges for manufacturers. Tighter profile tolerances, wider product ranges, and compressed lead times present production challenges for producers running older equipment or those contemplating a move into this market. Some developments in equipment and processes that are important to producing secondary structural members include quick-change roll form tooling systems and tooling that can improve the productivity of roofing components- Cee's, Zee's, Eave Struts, Channel, and Base Angle.

In 2005 precision stamper Weiss-Aug of East Hanover, N.J., achieved a reject rate of less than 1 part per million. The company credits the success to meticulous planning and almost flawless execution. Such an approach applies for Weiss-Aug even when it comes to uncoiling metal.
Control of engineering changes for automotive components and assemblies requires cooperation and communication among groups within a company, as well as with outside suppliers. Changes must be initiated, communicated, implemented, and verified enterprisewide.
