Q:What is the surface treatment standard of welded rebar mesh in China?

In China, the surface treatment standard for welded rebar mesh often involves galvanization. Galvanization is a common method used to enhance the corrosion resistance of steel mesh. The process involves applying a protective zinc coating to the surface of the mesh, which helps to prevent rust and prolong the lifespan of the product. The surface treatment standard for galvanized welded rebar mesh in China typically follows the national standard GB/T 13912-2020, which outlines the requirements for hot-dip galvanization of iron and steel products. This standard specifies the minimum coating thickness, adhesion, appearance, and other quality parameters for galvanized coatings. The adhesion of the coating should be sufficient to withstand normal handling and transportation without flaking or cracking.
