Combined with the characteristics of the engineering structure, a layer of steel mesh is arranged in the concrete of the container stack surface. The fineness of the thickness control of the steel mesh protective layer not only affects the appearance quality and cracks of the surface concrete, but also directly determines the durability and service life of the concrete, affects the construction quality, and reflects the production process and technical level of the construction unit.
