1. Scope:

1.1 This specification covers extruded 6061-T6 aluminum-alloy standard structural profiles.

1.2 The profiles are limited to I-beams, H-beams, channels, angles, tees, and zees.

Note 1-For other extruded profiles in other alloys and tempers refer to Specification B221.

1.3 Alloy and temper designations are in accordance with ANSI H35.1 [ANSI H35.1M]. The equivalent Unified Numbering System alloy designation is that in Table 1 preceded by A9, or A96061 for alloy 6061 in accordance with Practice E527.

1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.

1.5 The values stated in either inch-pound or SI units are to be regarded separately as standard. The SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems will result in nonconformance with the specification.
