Aluminum plate refers to boards processed by rolling aluminum ingots. It features lightweight and corrosion resistance; we use raw materials with the highest domestic standards for surface flatness and roughness. To prevent scratches during production and maintain a smooth surface, the plates are covered with a blue protective plastic film. Common thicknesses include: 0.2, 0.5, 0.8, 1.0, 2.0, etc. (unit: mm).
