Due to the fact that the surface of the exterior wall sandwich panel is made of aluminum zinc plated steel plate, some users have also raised questions about whether the thermal sandwich panel will rust?
Below, the editor will introduce in detail that this type of steel plate is of high quality, good hardness, and relatively cheap, making it very suitable for building use. The surface of the aluminum zinc plated steel plate is smooth, flat, and magnificent, with a special coating structure that gives it excellent corrosion resistance. After the aluminum zinc layer is plated on the surface, the corrosion resistance is greatly improved, which not only saves materials but also exerts good economic and environmental advantages. Due to the dense product of zinc corrosion and oxidation, the reaction speed is very slow, and the overall corrosion resistance is greatly improved. Moreover, the metal wall cladding panel has uniform color and can be formed in one go without the use of any adhesive between the layers. This avoids the cracking phenomenon caused by the adhesive due to long-term weathering, and also prevents air and water vapor from entering the interior of the board, which can corrode the board. That is to say, under normal circumstances, wall panel will not rust.
