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。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，会大大影响铝扣板的使用寿命。
第二、表面处理。
铝扣板的表面处理主要有以下几种：静电喷涂、烤漆、滚涂、珠光滚涂、覆膜。
以下是详细说明各板材表面处理工艺：
1、覆膜工艺：直接在铝基材上高温压铸上一层厚度为18--25C的PVC膜，缺点就是表面易变色。
2、滚涂工艺：是在表面滚涂上一层高分子涂料，优点是经久耐用不易变色。
3、滚涂丝印：滚涂的板的基础上又进行一次丝网印刷，效果是使本来单一的滚涂板变得颜色丰富。滚涂热渗转印（又称热渗透印）：和丝印一样是在滚涂板的基础上进行印刷，只不过是热渗透印法将油墨通过高温的方式升华后渗透到滚涂层里面去了，便面摸是感觉不到凹凸不平，从而感觉这是区别丝印的地方，热渗透印刷是数码方式，颜色可以由N种组成。但丝印只能是由一到种颜色组成。
4、磨砂工艺：在铝基板的上面进行拉丝，而后过光油的制造过程。市面上最普遍的一种板材。
第三、工艺。
所谓工艺就是板材有表层的粘合，这是消费者经常忽略的一块。如果工艺不好对于产品的使用寿命影响非常大，市场上的铝扣板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。建议进行铝扣板选择时，一定要了解清楚这一块。
