The difference between curtain wall aluminum veneer and aluminum honeycomb panel

Aluminum veneer and curtain wall aluminum veneer have been recognized by the market because of their good quality. In fact, it is still difficult to distinguish the characteristics of curtain wall aluminum veneer and aluminum veneer. Let\'s listen to the introduction of Kaimai metal building material aluminum veneer manufacturer.

Compared with the curtain wall aluminum veneer, the surface of the honeycomb aluminum plate can reach 1500mm × 4500mm, because the honeycomb aluminum plate is a composite material, and the internal aluminum honeycomb makes the plate itself fully able to bear its own weight, so there is no need to add any reinforcement. However, when the width of ordinary curtain wall is more than 1m and the length is more than 2m, stiffening ribs must be welded on the back of the plate. Moreover, because the thermal expansion coefficient of the stiffener is different from that of the board itself, after several times of alternating hot and cold, generally within half a year to one year after completion, the board surface will appear uneven phenomenon.

In terms of technology: curtain wall aluminum veneer is a single-layer product, the processing is relatively simple, but the accuracy is not high; honeycomb aluminum veneer as a composite product, the processing speed is slow, the capacity is small, but the accuracy is high.

In terms of their respective characteristics: curtain wall aluminum veneer is an ordinary non-composite panel, and its thickness of 3MM curtain wall aluminum veneer is generally 15-20% lower than 25MM aluminum honeycomb panel. In buildings, 4MM thick aluminum veneer is less used in buildings due to its own weight and forming reasons. The cost of curtain wall aluminum veneer with this thickness is only about 5% different from that of aluminum honeycomb panel Products. Wuhan honeycomb aluminum plate is a kind of composite plate, which has the advantages of high strength, light weight, large surface, good flatness, convenient installation and maintenance, reusable, environmental protection, good thermal expansion and shrinkage performance.

From the installation point of view, the buckle cover system adopted by aluminum honeycomb panel can choose two systems: hidden glue seam and exposed glue seam. Since both systems will consider the influence of thermal expansion and cold contraction, the surface of the panel can expand and contract freely in four directions, thus greatly reducing the influence of temperature stress on the flatness of the panel. The surface of ordinary single-layer aluminum plate is easy to warp due to exposed glue seam, and installed on the keel with the installation code, temperature stress there is no suitable space to release.
