This specification covers cold-formed electric resistance or electric induction welded carbon structural steel tubing in round, square, rectangular, or special shapes that are zinccoated (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.
Units—The values stated in either SI units or inchpound 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 nonconformance with the standard.
