Scope of standard

1.1 This specification covers cold-formed electric resistance or electric induction welded carbon structural steel tubing in round, square, rectangular, or special shapes that are zinc-coated (galvanized) on the exterior surface only, in continuous coating lines by the hot-dip process. The tubing can be manufactured from hot-rolled or cold-rolled steel. This product is intended for applications where corrosion resistance and mechanical properties are required. This product is available in several zinc coating weights [masses], strengths, and chemical compositions. 1.2 Units - The values stated in either SI units or inch-pound units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system is to be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
