ASTM A1063/A1063M-22 PDF

Full title and description

Standard Specification for Steel Sheet, Twin‑Roll Cast, Zinc‑Coated (Galvanized) by the Hot‑Dip Process — specification covering coils and cut lengths of twin‑roll cast steel sheet that have been hot‑dip zinc coated (galvanized). It defines permitted chemical compositions, mechanical property requirements for various designations (commercial steel, structural steel, and high‑strength low‑alloy steels), and zinc coating mass/weight and bending requirements for coated products.

Abstract

This specification applies to steel sheet produced by the twin‑roll cast process and hot‑dip galvanized in coils and cut lengths. It establishes designation/grade/class options, mandatory chemical analyses, mechanical property limits (yield, tensile, elongation), and coating weight/mass and performance tests for the zinc coating. Units are provided in inch‑pound (A1063) and SI (A1063M) versions.

• ICS / categories: 77.140.50 — Flat steel products and semi‑products.
• Edition / version: A1063/A1063M‑22 (text issued as the 2022 revision).

Scope

The standard covers twin‑roll cast steel sheet, hot‑dip galvanized, supplied in coils or cut lengths. It specifies available thickness and width limits (up to about 0.078 in / 2.0 mm thickness and up to ~79 in / 2000 mm width in typical listings), allowable designations/grades/classes, applicable coating designations/weights, and references to related ASTM coating and test methods (for example A924/A924M where applicable). The specification includes both inch‑pound (A1063) and SI (A1063M) unit systems.

Key topics and requirements

• Definition of product form: twin‑roll cast steel sheet supplied in coils and cut lengths.
• Designation categories: commercial steels (CS Types A, B, C), structural steels (SS), and high‑strength low‑alloy steels (HSLAS) with specific chemical and mechanical requirements.
• Chemical composition and mandatory heat analysis requirements for each designation.
• Mechanical property limits: minimum yield strength, tensile strength, and elongation as required by grade/class.
• Zinc coating specifications: coating designation/weight (mass) options, triple‑spot and single‑spot test considerations, and coating bending/performance tests.
• Unit systems and ordering: separate inch‑pound (A1063) and SI (A1063M) requirements; purchaser must specify which system.

Typical use and users

This specification is used by steel producers, galvanizers, fabricators, and purchasers specifying galvanized twin‑roll cast sheet for applications such as building components, light structural parts, and other uses where the combination of the twin‑roll cast production route and galvanizing is acceptable. It is relevant to quality/control engineers, procurement teams, metallurgists, and standards compliance personnel.

Related standards

Commonly referenced or related ASTM standards include A924/A924M (requirements for metallic coated sheet), applicable test methods for chemical analysis and mechanical testing, and other ASTM specifications dealing with galvanized and metallic‑coated steel products. Users should consult the referenced standards list in the specification for the exact cross‑references.

FAQ

Q: What is this standard?

A: ASTM A1063/A1063M‑22 is a 2022 ASTM standard specification that defines requirements for twin‑roll cast steel sheet that has been hot‑dip galvanized, including chemical, mechanical and coating requirements.

Q: What does it cover?

A: It covers coils and cut lengths of twin‑roll cast steel sheet zinc‑coated by the hot‑dip process, specifying designations, grades, chemical composition and mandatory tests, mechanical property limits, and zinc coating mass/weight and performance requirements. It also provides both inch‑pound and SI units (A1063 and A1063M).

Q: Who typically uses it?

A: Steel manufacturers using twin‑roll casting, galvanizers, fabricators, procurement and quality engineers, metallurgists, and anyone specifying or accepting galvanized twin‑roll cast steel sheet for manufacturing or construction applications.

Q: Is it current or superseded?

A: The A1063/A1063M‑22 edition was issued in 2022 (Nov 1, 2022). Subsequent editions of the same designation have been published by ASTM (for example A1063/A1063M‑25), so A1063/A1063M‑22 should be treated as a historical/earlier revision if a later edition is specified or required by contract; always confirm which edition is called out in procurement documents.

Q: Is it part of a series?

A: Yes — A1063/A1063M is part of a family of ASTM specifications for metallic‑coated and coated steel sheet products and falls under Book of Standards Volume 01.06 (committee A05 – metallic‑coated iron and steel products). It is issued in paired inch‑pound (A1063) and SI (A1063M) formats.

Q: What are the key keywords?

A: twin‑roll cast, galvanized, hot‑dip, zinc coating, steel sheet, coating weight, HSLAS, structural steel, A1063, A1063M.
