At present, the commonly used aluminium sheet is 0.5 mm and 0.8 mm, and the width is generally one meter wide, so it is easy to implement. Work.
Material, if there is no special requirement for strength, you can choose 1060. If there is special requirement for strength and material, you can choose 3003 material with a slightly higher price. Because of the high price of other materials, the amount of anti-corrosion and heat preservation aluminium skin is not large, so it is not recommended to choose here.
