Referring to fig. 1, 2 and 3, which are schematic views of a preferred embodiment of the present invention, the present invention relates to a square aluminum plate, which comprises: a base layer formed by sequentially leaning a plurality of aluminum profile square tubes 1 together in parallel in the horizontal direction; and the aluminum plates 2 respectively cover the upper side and the lower side of the base layer, and the aluminum plates 2 are adhered with the base layer through glue 3. Preferably, the shape and the size of the aluminum profile square pipes 1 are consistent, and the aluminum profile square pipes 1 which are leaned together side by side can be connected and positioned through adhesion or a buckling mode, so that a stable flat base layer is obtained. The aluminum plates 2 on the upper and lower sides of the base layer are preferably in a full plate form, so that a seamless composite shape is obtained, and the plate is flat and not easy to deform. The adhesive side surface of the aluminum profile square tube is provided with a ventilating part 11, the ventilating part 11 is adapted to the adhesion position of an aluminum plate and a base layer, external air permeates into the adhesive position of the aluminum plate and the base layer, the glue 3 is PUR glue and a reactive PU hot melt adhesive, the glue 3 is thermally melted into fluid and then coated on the aluminum plate and/or the base layer, and the aluminum plate 2 covers the base layer, is adhered and cooled, and then the glue layer is condensed to play a role in adhesion; then, the air introduced through the air permeable part 11 permeates, moisture existing in the air and moisture attached to the surface of the adherend react with the glue 3, and chain extension is performed to generate a high polymer having high cohesion, so that the adhesion, heat resistance, low temperature resistance, and the like are remarkably improved, thereby obtaining an aluminum composite panel having stable performance.
