Reinforced polystyrene board

Abstract

A reinforced polystyrene board, includes a grid reinforcer arranged in a board surface of a polystyrene board, so as to improve a tensile strength and a folding strength of the polystyrene board, and the grid reinforcer is made of a glass fiber grid, a metal grid, or a man-made fibers grid. A protective layer of the polystyrene board arranged outside of the reinforcer isolates the reinforcer from an external environment, so as to improve the corrosion resistance and the durability of the reinforcer.
