整个铝单板工程项目的铝单板并不是直接按图纸一次性生产完备，直接交给施工方。而是一批货一批货生产完成后，让施工的工人安装完备之后，然后再进行下一批次的生产和加工。这就要求铝单板加工厂家的产品误差不能太大，起始的一个很小的误差，则将会使后来的铝单板加工面临数据上的难题，产品易遇到安装不上的难题，正所谓“失之毫厘，谬以千里”。
The aluminum single board of the whole aluminum sheet project is not directly produced in one time according to the drawings, and is directly handed over to the constructor. But after the production of a batch of goods is completed, the construction workers are fully installed, and then the next batch of production and processing. This requires a product error can not be single aluminum plate processing factory is too large, a very small initial error, it will make the later processing of single aluminum plate facing the problem data, easy installation is not the problem, is the so-called "a difference".
在这方面，整个铝单板加工行业其实是有相关的国家推荐标准，在这个标准中，对相应的参数规定的非常仔细严格。通常铝单板的尺寸、规格是由厚度、长度、宽度、折边高度、对角线差等组成。长和宽决定了整个铝单板的基本形状，而厚度则可以影响着整个铝板的性能。
In this regard, the whole aluminum sheet processing industry is actually related to the national recommendation standard. In this standard, the corresponding parameters are carefully and strictly regulated. The size and specification of the aluminum sheet is usually made up of thickness, length, width, height of folded edge, diagonal difference and so on. The length and width determine the basic shape of the whole aluminum sheet, and the thickness can affect the performance of the whole aluminum plate.

无论铝单板板型如何，厚度上误差范围在±0.1mm以内。当铝单板长宽尺寸小于或等于2000mm的时候，长度和宽度所允许的较大误差是1mm。长宽尺寸大于2000mm时，长度和宽度的误差均不能超过1.5mm。
The error range of the thickness is less than 0.1mm, regardless of the aluminum sheet type. When the length and width of an aluminum sheet is less than or equal to 2000mm, the maximum error allowed by the length and width is 1mm. When the length and width are larger than 2000mm, the error of length and width can not exceed 1.5mm.
折边高度的误差范围与铝单板板面大小没关系，永远不能超过0.5mm。而对角线差所允许的误差范围是，当铝单板长度小于等于2000mm时，允许误差值为2mm；若长度大于2000mm时，误差值不能超过3mm。
There is no relation between the error range of the height of the folded edge and the size of the plate surface of the aluminum sheet, and can never exceed 0.5mm. The allowable error range of diagonal difference is that when the length of aluminum plate is less than or equal to 2000mm, the allowable error is 2mm. If the length is greater than 2000mm, the error value can't exceed 3mm.
铝单板的钣金加工是在生产线上，由技术工人在机器上进行加工制作，由于各种原因，会使得加工出来的铝单板可能存在一定的误差，但这个误差必须控制在一定的范围之内，否则即为不合格的产品。这些误差必须尽可能的减小，完全避免的话则更好！无论是钣金加工，还是喷涂过程，都必须要注意精确性。
Sheet metal processing aluminum single plate is in the production line, by skilled workers in machine production, due to various reasons, the single aluminum plate makes the processing out there may be some error, but this error must be controlled in a certain range, which is otherwise unqualified products. These errors must be reduced as much as possible and better if they are completely avoided! It is necessary to pay attention to accuracy, whether it is sheet metal processing or spraying process.
相信看了本文的介绍后，对铝卷生产厂家这方面也会有自己的一番认识，以后针对的等问题也能很好的解决。
I believe that after reading the introduction of this paper, we will have some understanding of the of aluminum coil manufacturer, and we can solve some other problems later.
