What do you want protecting your BEV?

C-STAR™ Protection Is an Innovative Vehicle Structure Steel Solution

Modern vehicles use a variety of structural components to protect passengers and internal systems. In the event of a collision, you want the structural components to absorb energy and/or deform in a controlled and predictable way.

Cliffs’ Steel Tubes As Reinforcement – known as C-STAR™ protection ─ when used in combination with structural components, contributes to the ability for structural components to absorb energy and/or deform in a more controlled and predictable way.

A C-STAR structure may be used in electric, hybrid, or ICE vehicles as reinforcements in rocker panels to protect passengers and/or batteries from a side-impact collision. C-STAR protection may also be used to protect motors, engines, electrical components, passenger compartments, storage compartments, and any area in a vehicle where this design is implemented.

  • Scalability to meet different performance requirements
  • Manufacturability
