First, material

目前市场上的铝材主要有以下几种：按铝材的产地分为普通铝材、广铝、西南铝;按铝材的国际标号又分为1100、3003、5005等标号;按铝材的合金强度分为H24、H18等;按铝材的韧性分为普通铝材、铝镁合金、铝锰合金。现在市场上销售的吊顶材料中大部分都采用普通的铝材，其特点是强度低，平整度一般，韧性强，不变形。没有好的基材，会大大影响铝方通的使用寿命。

At present, there are several kinds of aluminum materials on the market, which are divided into ordinary aluminum, wide aluminum, and South aluminum according to the producing area of aluminum, and are divided into 1100, 3003, 5005 and so on according to the international labeling of aluminum, and are divided into H24, H18 and so on according to the alloy strength of aluminum. Most of the ceiling materials sold on the market now use ordinary aluminum products, which are characterized by low strength, smooth planeness, strong toughness and no deformation. Without good substrate, the service life of aluminum can be greatly affected.

第二、表面处理

Second. Surface treatment

目前铝方通的表面处理主要有以下几种：喷涂、烤漆、滚涂、覆膜。其中喷涂、烤漆使用寿命短，容易出现色差，滚涂使用寿命居中，覆膜板又可分为普通膜与进口膜，进口膜的使用寿命基本上能达到20年不变色。

At present, the surface treatment of aluminum square passes mainly includes the following kinds: spraying, baking, rolling and laminating. The service life of the spraying and baking paint is short, the color difference is easy to appear, the roll coating service life is in the middle, the film covering board can be divided into the ordinary film and the imported film, and the service life of the imported film can basically reach 20 years.

第三、工艺

Third, process

所谓工艺就是板材有表层的粘合，这是消费者比较忽略的一块。如果工艺不好对于产品的使用寿命影响非常大，目前市场上的铝方通厂家处理工艺有很大的区别，很多小厂基本上是采取作坊式、工艺寿命降低。建议进行铝方通选择时，一定要了解清楚这一块。

The so-called technology is the surface gluing of boards, which is a neglected part of consumers. If the process is not good for the service life of the product is very large, at present, there is a great difference between the processing technology of the aluminum Fang Tong Factory in the market, and many small factories are basically the workshop style and the reduction of the process life. It is necessary for us to know this piece when we choose aluminum side pass.
