Roll-formed and stamped doorbeam |
摘要 |
A two-piece doorbeam including a relatively low-cost, low-strength body and a relatively high-cost, high-strength insert. The insert is hat-shaped and crimped within the body. The insert provides improved impact strength where needed, providing the doorbeam the desired strength at relatively low weight and low cost.
