Because both grades guarantee a minimum piece thickness – at least 1 ⁄ 4 inch (6.35 mm) for HMS 1, and 1 ⁄ 8 inch (3.175 mm) for HMS 2 – consignments have a high density. Both also have defined maximum dimensions (usually 60 in × 24 in or 1,524 mm × 610 mm), and should be prepared to facilitate handling and charging to a furnace.
