GB/T 9799-2024 Metallic and other inorganic coatings—Electroplated coatings of zinc with supplementary treatments on iron or steel
Abstract
This document specifies the requirements for treated zinc electroplating layers on steel, including the information to be provided to the supplier and the requirements for pre- and post-electroplating heat treatment. This document does not specify the surface condition of the base metal before electroplating, but defects on the surface of the base metal may adversely affect the appearance and performance of the coating. This document applies to treated zinc electroplating layers on steel. This document does not apply to: -- zinc electroplating layers on unprocessed steel plates, strips, and wires; -- zinc electroplating layers on coiled springs; -- zinc electroplating layers not intended for protective or decorative purposes. The thickness of the electroplating layer on threaded parts can be limited by thread grade or assembly size requirements.
