Full title and description
ASTM A526/A526M-90 — Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) by the Hot‑Dip Process, Commercial Quality. This designation covers commercial‑quality hot‑dip galvanized steel sheet supplied in coils and cut lengths; the A526/A526M-90 issuance was later withdrawn in 1994.
Abstract
Specification for commercial quality zinc‑coated (hot‑dip galvanized) steel sheet, providing requirements for the steel base, zinc coating mass, surface condition, mechanical properties and dimensional tolerances for material supplied in coils and cut lengths. The document is a short procedural/specification sheet (typically 2 pages in the ASTM Book of Standards).
General information
- Status: Withdrawn (withdrawn in 1994; inactive designation).
- Publication date: 1990 (designated A526/A526M-90).
- Publisher: ASTM International (American Society for Testing and Materials).
- ICS / categories: 77.140.50 — Flat steel products and semi‑products.
- Edition / version: A526/A526M-90 (dual inch/metric designation).
- Number of pages: 2 (short specification sheet typical of ASTM product specifications).
Scope
Applies to commercial‑quality steel sheet that has been coated with zinc by the hot‑dip process (galvanized). The scope typically defines the permitted product forms (coils and cut lengths), the required minimum zinc coating mass/weight, acceptable surface finish and imperfections, required mechanical property minima (tensile, yield, elongation where applicable), dimensional tolerances and required tests/inspection for acceptance. The specification used dual designations (inch and metric) as A526/A526M.
Key topics and requirements
- Material designation and product form: commercial‑quality hot‑dip zinc‑coated steel sheet (coils and cut lengths).
- Zinc coating mass/weight requirements (minimum coating mass per unit area and coating designations used by mills and purchasers).
- Surface condition and allowable imperfections (acceptance criteria for surface blemishes and spangle).
- Mechanical property minima and formability guidance (tensile strength, yield, elongation as applicable to commercial quality sheet).
- Dimensional tolerances (thickness/gage tolerances, width, length) and bend/forming characteristics for commercial use.
- Sampling, test methods and inspection requirements referenced to ASTM test procedures.
- Dual‑unit presentation (A526 for inch units and A526M for metric equivalents).
Typical use and users
Used by steel mills, galvanizing plants, metal fabricators, specifiers, architects, engineers and purchasers of commercial galvanized sheet for construction, building components (roofing, siding, flashings), HVAC ductwork, appliances and light manufacturing. Purchasing documents and procurement specifications historically referenced A526/A526M for commercial‑quality galvanized sheet until its withdrawal and consolidation into later ASTM galvanized‑sheet specifications.
Related standards
Closely related ASTM specifications include A525/A525M (general requirements), A527/A527M (lock‑forming quality), A528/A528M (drawing quality), A446 (structural quality steel sheet references) and the later consolidated series A653/A653M (which since the mid‑1990s became the principal designation covering commercial, drawing and structural quality zinc‑coated sheet). General requirements for metallic coating were also consolidated into other A‑series documents in the 1994 reorganization.

FAQ
Q: What is this standard?
A: ASTM A526/A526M-90 is (was) a short ASTM specification titled "Standard Specification for Steel Sheet, Zinc‑Coated (Galvanized) by the Hot‑Dip Process, Commercial Quality" used to define requirements for commercial‑quality hot‑dip galvanized steel sheet.
Q: What does it cover?
A: It covered commercial‑quality zinc‑coated (hot‑dip galvanized) steel sheet in coils and cut lengths, including coating mass requirements, surface condition, mechanical properties, dimensional tolerances and test/inspection provisions.
Q: Who typically uses it?
A: Steel producers, galvanizers, metal fabricators, procurement/specification authors, architects and engineers specifying commercial galvanized sheet for building and light manufacturing applications.
Q: Is it current or superseded?
A: It is withdrawn (withdrawn in 1994). Its content and the family of galvanized‑sheet specifications were consolidated and continued under other ASTM designations (notably the A653/A653M series in the mid‑1990s consolidation). Users should reference the current A653/A653M (or other current ASTM designations) for up‑to‑date requirements.
Q: Is it part of a series?
A: Yes — it belonged to the ASTM A05 committee product group covering steel sheet coated by the hot‑dip process and was historically one of several related designations (A525, A526, A527, A528, etc.) that were reorganized/consolidated in the 1994 update to the A653/A653M series.
Q: What are the key keywords?
A: Galvanized sheet, hot‑dip, zinc‑coated, commercial quality, coating mass, coils, cut lengths, A526, A526M.
