ASTM A1076/A1076M-20

Standard Specification for Cold Formed Carbon Structural Steel Tubing Made from Metallic Precoated Sheet Steel

ABSTRACT
This specification covers electric-resistance-welded structural tubing with round, square, rectangular, and special shapes and produced from precoated sheet steel with zinc (galvanized) or 55% aluminum-zinc alloy as coatings on both sides. This product is intended for applications requiring minimum mechanical properties and corrosion resistance of both exterior and interior surfaces. The standard addresses product size, material classification, ordering information, coating properties, chemical composition, mechanical properties of finished tube, flattening test, and oiling.
SCOPE
1.1 This specification covers round, square, rectangular, and special shape, electric-resistance-welded structural tubing produced from precoated sheet steel with the following coatings on both sides: zinc (galvanized) or 55% aluminum-zinc alloy or zinc-5 % aluminum alloy-coated. This product is intended for applications requiring minimum mechanical properties and corrosion resistance of both exterior and interior surfaces.  
1.2 This specification covers:  
1.2.1 Three grades of round tubing and three grades of shaped tubing, identified in Table 1 (Chemical Requirements), Table 2 (Mechanical Requirements of Round Structural Tubing), and Table 3 (Mechanical Requirements of Shaped Structural Tubing).  
1.2.2 Three different types of coating composition/designations (Section 7).  
1.3 This specification is applicable to orders in either inch-pound units (as A1076) or SI units (as A1076M). Within the text, SI units are shown in brackets. The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.4 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.  
1.5 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
