Range of Structural Steel Grades and Sections

Where applicable, these tables cover the full range of Australian produced structural steel hollow

sections, manufactured in accordance with AS 1163.

The hollow section sizes and steel grades listed in the Tables include:

• Grade C250 and Grade C350 Circular Hollow Sections (CHS)

• Grade C350 and Grade C450 Rectangular Hollow Sections (RHS)

• Grade C350 and Grade C450 Square Hollow Sections (SHS)

The grade designation (e.g. C250) is based on the nominal minimum yield strength of the steel (in

MPa). The prefix “c” is used before the value of the nominal yield strength of the steel to indicate

that the section is cold-formed. It should be noted that AS1163 only considers cold-formed structural steel hollow sections. The suffix “L0” denotes impact properties at 0℃ as specified in AS1163.

In these Tables:

• Grade “C250” refers to both C250 and C250L0

• Grade “C350” refers to both C350 and C350L0

• Grade “C450” refers to both C450 and C450L0

Yield stress and tensile strength

Table T2.1 lists the minimum yield stresses and tensile strengths for the structural steel hollow section grades covered by this publication and used for calculating the design capacities.
