建筑上使用的铝板包括单层铝板、复合铝板等多种材料，一般常常指单层铝板（也有叫单铝板或纯铝板），多用于建筑装饰工程中，近年来在铝板幕墙中单层铝板使用的较为多见。铝板幕墙也是幕墙的一种形式，简单地说是用铝板代替玻璃制成幕墙，铝板幕墙多用于作墙体蔽护和不采光的墙壁。
Aluminum sheets used in buildings include single-layer aluminum sheets, composite aluminum sheets and other materials, often referred to as single-layer aluminum sheets (also known as single-layer aluminum sheets or pure aluminum sheets), mostly used in building decoration projects, in recent years in the use of single-layer aluminum curtain wall is more common. Aluminum plate curtain wall is also a form of curtain wall, simply speaking, using aluminum plate instead of glass curtain wall, aluminum plate curtain wall is mostly used for wall protection and lighting wall.
国外的铝板幕墙一直选用单层铝板。单层铝板一般用纯铝板。铝板厚度为3mm，为了加强铝板板面强度，在铝板的背面，必须安装加强筋(现有的厂家不安)，加强筋用厚的铝带做成，先用闪光焊机把一颗颗螺丝帽焊在铝板背面然后把作加强筋的铝条钻孔套进螺丝内，用螺丝固定。我国为了减轻铝板重量，增加铝板强度，我们采用铝合金板，常选用21号防锈铝代号LF21压成的铝板作幕墙铝板。铝板厚度由原来3mm减少为2.5mm，该合金强度比纯铝板高出一倍左右。加强筋用LF21铝带，铝带的宽度厚度根据铝板板面而定，一般厚2-2.5mm，宽10-25mm。铝板幕墙的铝板背面为什么要安加强筋，是在外界正负压力的情况下，铝板一不会凹陷，二不会鼓出，这样就避免了铝板幕墙反复里外振动而发出的振动声音。如果需要隔音保温，可在铝板内侧，安放岩棉、矿渣棉或发泡处理。
The aluminum sheet curtain walls abroad have been selected for single layer aluminum plates. Single layer aluminum plates are usually made of pure aluminum plates. Aluminum plate thickness is 3mm, in order to strengthen the strength of the aluminum plate, in the back of the aluminum plate, must install reinforcement ribs (existing manufacturers are uneasy), reinforcement ribs made of thick aluminum strip, first with flash welding machine to weld a screw cap on the back of the aluminum plate and then the reinforcement of the aluminum rod borehole into the screw, fixed with screws. In order to reduce the weight of aluminium plate and increase the strength of aluminium plate, we use aluminium alloy plate. Aluminum plate made of No. 21 rust-proof aluminium code LF21 is often used as curtain wall aluminium plate. The thickness of aluminum plate is reduced from 3mm to 2.5mm, which is twice as high as that of pure aluminum sheet. LF21 aluminum strip is used for reinforcing ribs. The width and thickness of the aluminum strip are determined by the surface of the aluminum plate. Generally, the thickness is 2-2.5mm and the width is 10-25mm. The reason why the back of aluminum curtain wall should be strengthened is that under the positive and negative external pressure, the aluminum plate will not be sunken, two will not bulge, thus avoiding the aluminum curtain wall repeated inside and outside vibration and the vibration sound. If sound insulation is needed, the rock can be placed on the inside of the aluminum sheet, with rock wool, slag wool or foam treatment.

幕墙铝板表面处理，可分为二种方法，一种是阳极氧化，另一种是静电喷涂。阳极氧化的氧化膜一般在12μ以上，颜色只有古铜色和白色两种，颜色单调，更为严重的缺点是每块铝板板面的颜色深浅不一，许多块幕墙板组合在一起形成一个幕墙整体效果非常难看。这个缺点可以说无法消除，并非生产技术造成的，而是由于铝板并非是由一批号，化学成份，均有小的差别，再加上氧化时电解槽液电流密度等因素均无法完全一样，所以氧化后的颜色多少均有差异，单张看可能不明显，若都排在一起即非常明显。所以铝板幕墙的铝板表面处理，决不能用阳极氧化。
Curtain wall aluminum surface treatment can be divided into two methods, one is anodic oxidation, the other is electrostatic spraying. Anodized oxide film is generally more than 12 mu, the color is only bronze and white, the color is monotonous, the more serious drawback is that the color of each aluminum plate surface is different, many curtain wall panels together to form a curtain wall overall effect is very ugly. This disadvantage can not be eliminated, not due to production technology, but because the aluminum plate is not a batch number, chemical composition, there are small differences, coupled with oxidation when the electrolyte current density and other factors can not be completely the same, so the number of colors after oxidation are different, a single look may not be obvious, if all are That is very obvious. Therefore, the surface treatment of aluminum plate curtain wall must not be anodized.
幕墙铝板表面处理的另一种方法是静电喷涂。喷涂又分为粉沫喷涂和液体喷涂。粉沫喷涂材料主要为：聚氨酯、聚胀树脂、环氧树脂等原料配以高保色性颜料，可得到几十种不同颜色的喷涂粉沫。该喷涂粉沫，耐撞碰耐磨擦，在50公斤撞击下，铝板变形，喷涂层无裂纹，无掉层完整无损，抗稀酸及砂浆。的缺点怕紫外线长期照射，几年后易产生阴阳面颜色的差异。
Another way of surface treatment of aluminum curtain wall is electrostatic spraying. Spraying is divided into powder spray and liquid spray. Powder spraying materials are mainly polyurethane, swelling resin, epoxy resin and other raw materials with high color retention pigments, can get dozens of different colors of spraying powder. The spraying powder, collision resistance and abrasion resistance, 50 kg impact, aluminum plate deformation, spray coating without cracks, no drop layer integrity and no damage, dilute acid and mortar. The only shortcoming is that the long term exposure to ultraviolet radiation will lead to differences in color between yin and Yang after a few years.
