AS/NZS 1163 is the joint Australian/New Zealand Standard that outlines the specifications for cold-formed, electric resistance-welded steel hollow sections intended for structural applications. This standard sets out the requirements for manufacturing and supplying structural hollow sections with an emphasis on mechanical performance and chemical composition.

Steel Grade Classification for AS/NZS 1163 Stuctural Hollow Section
Under AS/NZS 1163, steel hollow sections are categorized into various grades based on their mechanical properties. These include:
C250
C350
C450
The numerical designation reflects the minimum yield strength of the material in megapascals (MPa), ensuring that each grade meets or exceeds the specified strength requirements.
