Steel vs.
Aluminum: UltraLight
Steel Auto Closure
The
UltraLight
Steel Auto Closure (ULSAC) program
is a study undertaken by the global steel industry to demonstrate the
effective use of steel in producing lightweight, structurally sound,
steel automotive closure panels that are manufacturable and
affordable. ULSAC began as a concept development program, which
produced concept designs for doors, hoods, decklids and hatches that
are up to 32 percent lighter than benchmarked averages and ten percent
lighter than best-in-class, while meeting stringent structural
performance targets. They can be fabricated in high volume using
manufacturing processes and materials that are current and affordable.
