The invention relates to the technical field of mechanical manufacturing of ship bodies, and specifically relates to an antiskid deck which is provided with a steel deck. The antiskid deck is characterized in that the outer part of the steel deck is wrapped with a glass fiber reinforced plastic plate; supporting columns which are arranged in a matrix form are mounted on the upper end surface of the glass fiber reinforced plastic plate which wraps the outer layer of the steel deck; connecting platforms of which the diameter is less than that of the supporting columns are arranged at the upper ends of the supporting columns; an antiskid glass fiber reinforced plastic plate is arranged on each connecting platform; connecting holes in match with the connecting platforms are formed in the antiskid glass fiber reinforced plastic plate, and water guide holes are formed in the antiskid glass fiber reinforced plastic plates among the connecting holes; water guide channels are formed among the glass fiber reinforced plastic plates which wrap the steel deck, the supporting columns and the antiskid glass fiber reinforced plastic plates. The antiskid deck has the advantages of being stable in structure, high in antiskid performance, high in connecting strength, and capable of regularly replacing.
