Aluminum is a non combustible material with a fire rating of A. The surface is treated by coating and has strong corrosion resistance. Aluminum products do not volatilize any harmful gas to human body, and can be completely recycled. It is easy to dismantle and assemble, light in weight, convenient in transportation, and can be reused for many times. Greatly reduce the building load. The middle interlayer contains a lot of air, which can be used for sound and heat insulation. Moisture proof, no harmful gas release. The strength of unit mass is large, the rigidity is high, and it is not easy to deform. It is easy to process and can be cut and folded at will. The surface has high flatness and good seismic performance. Fluorocarbon roll coating panel is generally used for aluminum honeycomb panel. The coating is finished at one time with small color difference, good leveling and reliable quality. It can keep the color of building exterior wall bright for a long time. It can withstand long-term sunlight and rain or industrial waste gas pollution, clean and bright, and has good adhesion and weather resistance.
