ASTM International Standard Specification for Cold-Formed Welded Carbon Steel Hollow Structural Sections (HSS) ASTM A1085-13

This specification covers cold-formed welded carbon steel hollow structural sections (HSS) for welded or bolted construction that are used in, although not limited to, 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. This HSS is produced in welded sizes with a periphery of not more than 88 in. [2235 mm] as well as a specified nominal wall thickness of at least 0.148 in. [3.8 mm] and not more than 0.875 in. [22 mm]. The standard addresses areas such as ordering information, the steel-making process, HSS manufacture, heat analysis, product analysis, tensile requirements, flattening test, permissible variations in dimensions, number of tests, retests, test methods, rejection, certification, product marking, packing and loading, and government procurement.
