铝卷的加工并不是直接按照图纸一次生产完全，直接交给施工方。而是在一批货物生产完成后，先由施工人员进行安装，安装结束后再进行下一批的生产加工。这样一来就要求厂家在加工保温铝卷时不能有太大的误差，因为加工时的一个小小的误差都会对后续的产品施工产生很大的影响。因此铝卷的加工应选择可靠的厂家，这不仅是对产品质量的保证，同时也可以确保施工进度的顺利推进。
The processing of aluminum coil is not directly produced at one time according to the drawings, but directly handed over to the construction party. Instead, after the production of a batch of goods is completed, the construction personnel shall install it first, and then carry out the production and processing of the next batch after the installation. In this way, the manufacturer is required not to have too much error in processing the thermal insulation aluminum coil, because a small error in processing will have a great impact on the subsequent product construction. Therefore, reliable manufacturers should be selected for aluminum coil processing, which not only ensures the product quality, but also ensures the smooth progress of construction progress.
