1.1 This specification covers laser beam or laser hybrid welded, built-up, carbon steel, sharp-cornered profiles (SCP) square, rectangular, or custom shape structural tubing for welded, riveted, or bolted construction. This specification does not include weathering steels, since most cannot be welded by these methods. SCP tubing is used in, but not limited to, the following applications: buildings and structures, including architecturally exposed steel structures (AESS); architectural steel profiles such as curtain wall, staircases, and others; industrial; and general structural applications.NOTE 1: There is no standard for other sharp-cornered laser or laser hybrid welded carbon steel structural shapes, but Appendix X1 provides guidance on their specification.1.2 The SCP structural tubing sections produced to this specification have a perimeter of 2845 mm [112 in.] or less and wall thickness of between 4.76 and 38.1 mm [3/16 and 1.50 in.]. The thicknesses of walls within a specified SCP tube shape can be different.1.3 This specification establishes the minimum requirements for manufacturing of built-up, SCP laser, and laser hybrid welded carbon steel tube sections and requires the welds to, at a minimum, match the tensile and yield strength of the base metal.NOTE 2: Product covered by this specification is manufactured in small lots on dedicated production lines. Product quality requirements are ensured through welding procedure qualification of the manufacturing facility in accordance with AWS, ISO, or CSA requirements. In addition to the standard weld inspection and weld quality requirements, the purchaser can specify higher levels of weld inspection; Supplementary S1 tensile, S2 bend, and S3 Charpy V- notch lot testing; and other requirements.NOTE 3: Because of the varying requirements of the end-use applications, four different length tolerance and weld inspection levels may be specified.1.4 This specification uses Specifications A36/A36M, A572/A572M, EN 10025-2, or EN 10025-3 for the chemical and mechanical requirements of the designated strength grade.1.5 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.1.6 Units—This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply. The values stated in either inch-pound units or SI 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 nonconformance with the standard.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 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.
