This standard specifies the preferred sizes, or dimensions, of wrought metal products manufactured from steel (hot-rolled and bright), copper, copper alloys, aluminium and aluminium alloys.

Scope

This Standard applies to round, square, hexagonal, and rectangular metal products conventionally known as rod, wire and bar, and to flat metal products conventionally known as plate, sheet, and strip.
