The Ultralight Steel Auto Closure (ULSAC) Program is a study undertaken by the global steel producers to demonstrate the effective use of steel in producing lightweight, structurally sound steel automotive closures that are manufacturable and affordable. ULSAC began as a concept development program, producing lightweight designs for doors, hoods, decklids and hatches that are up to 32% lighter than the average benchmark. The program continued to the manufacture of steel frameless door demonstration hardware that achieves dramatic results in mass reduction and performance, yet is manufacturable in high-volume at affordable costs.
