光伏建筑是太阳能发电的一种新概念，是利用建筑物受光面积和支撑结构，利用安装在建筑物围护结构外表面的太阳能发电装置来提供电力，不仅可以扩大清洁能源的有效使用面积，而且不占用城市地面空间，维护起来也比较方便，已被越来越多的重视可再生能源的国家所采用。但怎样将光伏板安装的建筑物上，应尽可能轻便，减少对建筑物的负重，同时又要保证支架的美观性和长达25 年以上的使用寿命，且不需要经常给支架做维护，这就需要一种既美观又耐腐蚀的光伏支架轻便材料——镀铝锌镁板。

Photovoltaic building is a new concept of solar power generation, is to use building light area and support structure, installed in the building envelope surface solar power device to provide power, not only can expand the effective use of clean energy area, and does not take up urban ground space, maintenance is more convenient, has been more and more attention to renewable energy countries.But how to install the photovoltaic panel on the building, should be as light as possible, reduce the weight of the building, at the same time to ensure the beauty of the support and the service life of more than 25 years, and do not need to often maintain the support, which requires a beautiful and corrosion resistant photovoltaic bracket lightweight material —— aluminum plated zinc magnesium plate.

镀铝锌镁板一般属于浸镀锌，经过前镀敷处理，通过向热浸镀铝液中添加微量镁和稀土元素。此外，镀铝锌镁板还具有在严峻条件下优秀的加工性能（如在拉伸、冲压、折弯、油漆、焊接等方面），镀层硬度高，具有卓越的耐损伤性。镀铝锌镁板与普通的镀锌及镀铝锌产品相比，镀敷附着量少却能实现更出色的耐腐蚀性，由于具有这种超强耐腐蚀性，镀铝锌镁板在某些领域可代替不锈钢或铝使用。切割端面部分的耐腐蚀自我愈合功效更是镀铝锌镁板产品的一大特点。

Aluminized zinc magnesium plate is generally dip galvanized, after the front plating treatment, by adding trace magnesium and rare earth elements to the hot dip aluminum plating solution.In addition, aluminized zinc magnesium plate also has excellent processing performance under severe conditions (such as in stretching, stamping, bending, painting, welding, etc.), high coating hardness, with excellent damage resistance.Compared with ordinary galvanized and galvanized galvanized products, less attachment can achieve better corrosion resistance, because of this super corrosion resistance, aluminum galvanized magnesium plate can in some fields be used instead of stainless steel or aluminum.The corrosion resistance and self-healing effect of the cutting end surface is a major feature of aluminum-coated galvanized magnesium plate products.

镀铝锌镁板，由致密的合金镀层组成，它具有镀锌板、镀铝锌板所没有的优势。相同涂层情况下，镀铝锌镁使用寿命是镀锌的10～20 倍。镀镁铝锌原本的目的就是利用最薄的镀层金属来达到更厚的镀锌层所能达到的效果。其使用寿命长，切口部位镀层具有自愈性，不需要后浸镀后加工的工序。

Aluminium-plated zinc magnesium plate, composed of dense alloy coating, it has the advantage of galvanized plate, galvanized zinc plate does not have.Under the same coating condition, the service life of galvanized magnesium is 10~20 times that of galvanized magnesium.The original purpose of magnesium-coated aluminum and zinc is to use the thinnest coating metal to achieve the effect of a thicker galvanized coating.Its service life is long, the incision part coating has self-healing, does not need the post-dip plating processing process.

光伏建筑应用镀铝锌镁材料既在建筑设计上增加了创新意识，体现了洁净、绿色的理念，又为城市的电力供应提供了多一种选择，无论从美学还是实用角度来看，都具有很大的应用价值。镀铝锌镁钢板已在光伏建筑应用上表现出明显的优势，可以继续从材料研发、技术标准等入手，降低材料成本，积极推动镀铝锌镁钢板在光伏产业的健康发展。

The application of aluminum-coated galvanized magnesium materials in photovoltaic buildings not only increases the sense of innovation in the architectural design, reflects the concept of clean and green, but also provides a multiple choice for the urban power supply, both from the aesthetic or practical perspective, it has great application value.Aluminized zinc magnesium steel plate has shown obvious advantages in the application of photovoltaic buildings, we can continue to start from material research and development, technical standards, reduce material costs, and actively promote the healthy development of aluminum coated galvanized magnesium steel plate in the photovoltaic industry.
