Decorative plate capable of improving corrosion resistance

A decorative plate capable of improving corrosion resistance comprises a plate body and a decorative metal protecting strip connected onto one surface of the plate body, wherein the decorative metal protecting strip comprises an aluminium strip base layer and a metal coating covering the upper surface of the aluminium strip base layer, the plate body comprises an elongated base plate and multiple rib blocks longitudinally arranged on the base plate at intervals, multiple holes formed at intervals are formed in each rib block, multiple combination grooves matched with the rib blocks are formed in the aluminium strip base layer, multiple combination blocks matched with the holes are arranged in each combination groove, and the combination grooves and the rib blocks are bonded by the aid of glue. According to the decorative plate, the rib blocks and the holes are arranged, on one hand, the surface area of the position where the aluminium strip base layer and the plate body are combined can be increased, and the bonding firmness of the aluminium strip base layer and the plate body can be enhanced; on the other hand, the rigidity of the whole decorative plate can be enhanced, the overall load-carrying capacity of the decorative plate can be further improved, and the usage durability of the decorative plate can be enhanced.
