The Australian/New Zealand Standard for hot-rolled structural steel plates, floorplates and slabs, specifying material grades and properties.
AS/NZS 3678 specifies the requirements for hot-rolled structural steel plate, including chemical composition, mechanical properties (yield strength, tensile strength, elongation), impact testing requirements, and dimensional tolerances. Common grades include Grade 250 (minimum 250 MPa yield), Grade 300, and Grade 350. This standard is referenced by AS 4100 as the material specification for structural plate products used in Australian steel construction.
