一，查看铝板的外包装。好的包装不仅显示出铝板厂家的实力，舍得花大价钱在产品包装上付出，而且也显示出厂家比较重视产品的防护。另外也显示出厂家对铝板生产管理十分到位。
One, check the outer packing of the aluminum plate. Good packaging not only shows the strength of the aluminum plate manufacturer, but also pays for the product package, and it also shows that the manufacturers attach much importance to product protection. In addition, it is also shown that the manufacturer is very effective in the management of the aluminum plate production.
二，查看铝板的表面。好的铝板，表面无辊印、黑点、划伤、油斑、腐蚀、裂变等缺陷；板型平整，无明显弯曲；单张铝板对角线一致；整件铝板摆放整齐，每张铝板长宽一致。如铝板表面覆有保护膜，将保护膜揭开，至少查看整个宽度的板面，避免有缺陷被掩盖。
Two, look at the surface of the aluminum plate. Good aluminum, surface roller, black spots, scratches, grease, corrosion, fission and other defects; flat plate, no bending sheet aluminum; diagonal consistent; the whole plate neatly, each plate length and width consistent. If the surface of the aluminum plate is covered with a protective film, the protective film will be opened and at least the width of the plate is looked at at least to avoid the defects being covered.
三，用千分尺、米尺、游标卡尺等测量工具进行测量。根据需求，选择铝板厂家提供的产品进行测评。并根据所测尺寸的数量级选择不同的测量工具，对铝板的厚度、宽度、长度、不平度、对角线等产品进行测量，具体尺寸偏差可参考GB/T 3880。1-2006。每一次测量至少选择三个点进行测量，测算铝板尺寸或者误差是否均匀、是否都在国标之内。

Three, measured with micrometer, vernier caliper, meter measuring tools. According to the demand, select the products provided by aluminum plate manufacturers to evaluate. According to the size of the measured size, different measuring tools are selected to measure the thickness, width, length, roughness and diagonal line of the aluminum plate. The specific size deviation can be referred to GB/T 3880. 1-2006. At least three points are selected for each measurement to measure the size or error of the aluminum plate or whether it is within the national standard.
四，要求铝板厂家提供铝板材质合格证明单。好的铝板厂家都会对每批次的铝板进行成分、性能等方面进行测试。铝板厂家提供材质合格证明单后，查看材质单对应产品的成分、性能是否控制在国标范围之内，具体数值可参考GB/T 3880-2006。且要注意材质单必须加盖厂家的公章。如果在铝板的使用过程中出现问题，可以材质单作为依据对铝板进行检测，并像厂家提出质量异议。
Four, the aluminum plate manufacturer is required to provide the certificate of qualification for the material of the aluminum plate. A good aluminum manufacturer will test the composition and performance of each batch of aluminum plate. After the aluminum plate manufacturer provides the material qualification certificate, check whether the ingredients and properties of the material correspond to the national standard. The specific value can be referred to GB/T 3880-2006. And pay attention to the material sheet must be stamped with the manufacturer's official seal. If there is a problem in the process of using the aluminum plate, the material can be used as the basis for the inspection of the aluminum plate, and the quality objection is put forward by the manufacturer.
五，厂家售后服务。了解厂家的售后服务如何，如果遇到问题铝板厂家能否及时解决，这样才能更无后顾之忧。
Five, the after-sales service of the manufacturer. How to understand the after-sales service of the manufacturers, if the problem can be solved in time, this can be more worried.
