    The term minimized spangle has, for the most part, become obsolete. It has been used less and less over the past two decades, during which time the production of galvanized sheet switched largely to a spangle-free product. There remains a relatively smaller market for a spangle product. This ballot proposes to delete the term minimized spangle and to also replace the term regular spangle with spangle, as there is no longer a need for the qualifying adjective. These proposals follow the recent change to this document requiring the purchaser to specifically order spangle if required (see 5.2.8). An additional proposal is to add language to the Discussion for the definition of spangle-free (current to indicate that this is the typical manufacturing practice.
