The surface of the aluminium-zinc-silicon-coated sheet is characterized by a smooth, flat, and lustrous star pattern, with a base color of silver-white. The special coating structure gives it excellent corrosion resistance. The normal service life of the aluminium-zinc-silicon-coated sheet can reach 25 years, and it has good heat resistance, which can be used in high-temperature environments up to 315 degrees Celsius. The adhesion between the coating and the paint film is good, and it has excellent processing properties, allowing for stamping, cutting, welding, etc. The surface has very good electrical conductivity.
