This standard outlines the requirements for continuously hot-dip aluminum-zinc alloy metallic-coated steel strips and sheets with plain thicknesses ranging from 0.25 mm to 1.5 mm. It involves the uniform coating of both surfaces of cold-rolled steel coils.

IS 8910 outlines the general requirements for supplying aluminum-zinc alloy metallic-coated steel strips and sheets (plain). Meanwhile, IS 513 defines the specifications for the base metal used in cold-rolled low carbon steel strips for aluminum-zinc alloy metallic-coated steel strips and sheets (plain).

The cold-rolled strip is coated by immersing it in a bath of molten aluminum, zinc, and control elements at a temperature optimized to produce a consistent and fully adhering aluminum-zinc alloy metallic coating. Post-coating, the surfaces may undergo additional treatments, including temper mill passes, surface passivation, or other coatings, for various purposes. The base steel's chemical composition must conform to the requirements specified in IS 513.
