The reinforcing mesh panel unit 3 is composed of a multi-layer structure of a fiberglass mesh layer 31 and a corrosion protection layer 32, with reinforcing ribs embedded inside the fiberglass mesh layer 31 and the corrosion protection layer 32 located on both sides of the fiberglass mesh layer 31. This structure ensures that the reinforcing mesh panel unit 3 not only has high strength and tensile properties, but also effectively resists corrosion and aging. The reinforcing ribs in the fiberglass mesh layer 31 enhance the overall rigidity and anti-deformation ability of the material through a crisscross layout, allowing the reinforcing mesh panel unit 3 to maintain structural stability while withstanding external pressure.
