Scope

This document specifies the classification and grades of zinc-plated steel reinforcement, order content, appearance, dimensions, weight, and allowable deviations, technical requirements, testing methods, inspection rules, packaging, marking, and quality certificates. This document applies to zinc-plated ribbed and smooth steel reinforcement for reinforced concrete (hereinafter referred to as "steel reinforcement"), as well as binary and multicomponent alloy zinc-plated reinforcement. It does not apply to welded steel reinforcement nets and welded embedded reinforcement. For such products, it is recommended to conduct zinc-plated anti-corrosion treatment after welding. 1. Technical Requirements 1.1 Steel Reinforcement and Zinc Powder The base material for producing zinc-plated steel reinforcement shall comply with the provisions of GB 1499.1, GB 1499.2, and GB 13788. The zinc powder shall comply with the provisions of GB/T 6890, with a grade no greater than Level 3 and a particle size specification no greater than 30 μm. That is, commercially available qualified steel reinforcement and zinc powder. 1.2 Repair The zinc-rich coating used in the repair process shall comply with the requirements of the HG/T 3668-2020 "Zinc-Rich Primer" standard. 1.3 Requirements for the Zinc-Plated Layer 1.3.1 Appearance Refer to the requirements of the relevant zinc-plating standard GB/T 35505-2017. 1.3.2 Thickness The thickness grade shall refer to the basic data in the ASTM A1059/A1059M-2008 (2013) Standard Specification for Zinc Alloy Thermo-Diffusion Coatings (TDC) on Steel Fasteners, Hardware, and Other Products. 1.3.3 Mechanical Properties Follow the provisions of GB 1499.1, GB 1499.2, and GB 13788. 1.4 Process Performance The bending and reverse bending performance integrates the provisions of GB 1499.1, GB 1499.2, and GB 13788 and the technical requirements of GB/T 35505, and shall not be lower than the provisions of GB 1499.1, GB 1499.2, and GB 1
