Abstract
A roll-formed product is formed from a steel sheet having a tensile strength of not greater than 400 MPa and is locally reinforced. Such a roll-formed product is excellent in formability and shock absorbing ability and is of high strength. The roll-formed product can be used as, for example, a vehicle bumper. The roll-formed vehicle bumper can also be made at a lower cost.
