The invention relates to a processing method of high intensity and corrosion resistant hyperbolicity plastic plates and shells with steel meshes. The invention adopts the following technical proposal. The processing method of hyperbolicity plastic plates and shells with steel meshes is characterized in that the processing method comprises the following steps: 1. steel bars are made into steel meshes; positions of junctions of steel bars are fixed together; and the length of the sides of the grids of the steel mesh is less than the maximum span limit of the steel bars required by the viscosity force of the high pressure plastic casting fusant, and is also less than the maximum span limit of two-way arch bridges established inside the grids; 2. the steel meshes are arranged inside a mould of the required shape; the positions of the steel meshes are fixed; plastic is cast in the mould under high and medium pressure until both sides of the steel mesh are completely wrapped by the plastic body. By adopting the pro
