用途决定了铝皮的厚度和材质，现在铝皮往往是用于保温行业中，所以在选择铝皮的时候要考虑到保温管道的直径，直径越大选用的铝皮厚度就需要越厚，目前常用的铝皮是0.5和0.8mm的，宽度一般均采用一米宽幅的，这样便于施工。
Usage determines the thickness and material of aluminium sheet. Now aluminium sheet is often used in thermal insulation industry. So when selecting aluminium sheet, the diameter of insulation pipeline should be taken into account. The thicker the aluminium sheet used in general election, the thicker the thickness is. 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.
材质方面，如果对于强度没有特殊要求选择1060的即可，如果对于强度以及材质有特殊要求可选择价格稍高的3003材质，而其它材质由于价格太高所以在防腐保温铝皮方面用量不大，这里不建议选择。
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.

如何看铝皮的质量：铝皮的质量可通过外观，平整度以及厚度公差来辨别，优质的铝皮表面无油污，无色差以及划伤。这一点可在购买铝皮的时候通过外观即可辨别，所以建议没有铝皮购买经验的用户可以通过较简单的表面来辨别铝皮的质量，选择质量的铝皮，亦可以将铝皮平铺在地面，可以看铝皮是否有来回起伏的波浪，优质的铝皮均经过了矫正，不会有明显的波浪纹，厚度需要用的千分尺来测量，经过以上的几个步骤可以选择出质量好的铝皮。
How to look at the quality of aluminium skin: The quality of aluminium skin can be distinguished by appearance, flatness and thickness tolerance. The surface of high quality aluminium skin is free of oil stain, color difference and scratch. This can be distinguished by appearance when purchasing aluminium skin, so it is suggested that users without experience in purchasing aluminium skin can distinguish the quality of aluminium skin through the simplest surface, select aluminium skin of good quality, and also can lay aluminium skin on the ground, to see if there are fluctuating waves in aluminium skin, high-quality aluminium skin is equal. After correction, there will be no obvious ripple. The thickness needs to be measured by professional micrometer. After the above steps, the aluminium sheet with good quality can be selected.
