There were no specific Chinese National Standards (GB/T) dedicated solely to Zinc-aluminum-magnesium (ZAM) steel coils in China. However, similar to the situations in other countries, the properties and performance of ZAM-coated steel typically fall under existing standards for coated steel products.
In China, the relevant standards for ZAM-coated steel would generally be covered by the Chinese National Standards (GB/T) related to continuously hot-dip coated steel products with various types of metallic coatings, including zinc, zinc-aluminum alloy, and aluminum-zinc alloy coatings.
The most common standard used for this type of coated steel in China is:
GB/T 2518-2019: Continuous hot-dip zinc-coated steel sheets and coils.
While GB/T 2518-2019 does not specifically mention ZAM steel, it covers the requirements for continuously hot-dip zinc-coated steel sheets and coils, which includes various types of zinc-aluminum alloy coatings. Zinc-aluminum-magnesium (ZAM) coating would fall under the category of zinc-aluminum alloy coatings in this standard.

There was no specific ASTM standard dedicated solely to Zinc-aluminum-magnesium (ZAM) steel coils in the United States. Instead, the properties and performance of ZAM-coated steel typically fall under existing standards for coated steel products.
The most common standard used for ZAM-coated steel in the US is ASTM A1046/A1046M - Standard Specification for Steel Sheet, Zinc-Aluminum-Magnesium Alloy-Coated by the Hot-Dip Process. This specification covers the requirements for steel sheet, in coils and cut lengths, coated by a hot-dip process with zinc-aluminum-magnesium alloy.
ASTM A1046/A1046M outlines the chemical composition, mechanical properties, coating weight, thickness, and other performance characteristics of ZAM-coated steel. It sets the standards for the quality and properties of this advanced coating technology and is used as a reference by manufacturers and users in the industry.

There were no specific British Standards (BS) or European Standards (EN) dedicated solely to Zinc-aluminum-magnesium (ZAM) steel coils in the United Kingdom. Similar to the situation in the United States, the properties and performance of ZAM-coated steel typically fall under existing standards for coated steel products.
In the UK, the relevant standards for ZAM-coated steel would generally be covered by European standards for continuously hot-dip coated steel products, which include zinc-aluminum-magnesium alloy coatings. The most common standard used for this type of coated steel in Europe is:
