The present invention relates to a glass-fiber reinforced plastics (GRP) panel door for flame and crime prevention which can perform both of a flame retardant function and a crime prevention function. The GRP panel comprises: a pair of front side and rear side GRP panels having fire resistance and forming front and rear sides of a door in a plate shape; protruding frames respectively protruding from both inner sides of the front side and rear side GRP panels; metal plates tightly fixed on the inner sides of the protruding frames of the front side and rear side GRP panels in a state of being inserted between the front side and rear side GRP panels, and reinforcing deflection of the front side and rear side GRP panels; fire-resisting woods having protrusions inserted in an insertion space between the protruding frames of the front side and rear side GRP panels, and fixed with coupling pins while attached to the outer surface of the protruding frames of the front side and rear side GRP panels; adhesive materials applied to contact sides where the front side and rear side GRP panels and the fire-resisting woods come into contact with each other; and a flame retardant urethane foam filled in a space between the front side and the rear side GRP panels and providing a sound insulation property. |
