ASTM A1085/A1085M-22

1.1?This specification covers cold-formed welded carbon steel hollow structural sections (HSS) for welded or bolted construction. These shapes are utilized in but not limited to the following applications: buildings, bridges, towers, cranes, sign supports and poles, off-shore production and drilling platforms, roll-over protective structures (ROPS), falling object protective structures (FOPS), and amusement rides.

1.2?This HSS is produced in welded sizes with a periphery of 88 in. [2235 mm] or less, and a specified nominal wall thickness of 0.148 in. [3.8 mm] or greater and 1.000 in. [25.4 mm] or less.

1.3?The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply unless the M designation of this specification is specified in the order.

1.4?The text of this specification contains notes and footnotes that provide explanatory material. Such notes and footnotes, excluding those in tables and figures, do not contain any mandatory requirements.

1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
