钢铝结构的阳光房在国外主要是因为某些阳光房过大，由于钢材的强度高，并且焊接方便，所以采用钢框架，铝焊条。建造很大的阳光房。而在国内（尤其是上海）因为阳光房是一种新生事物，且价格较高，所以为了减少成本，采用了钢铝复合即（铝包钢的阳光房），钢作为结构主体满足了强度问题，而铝作为表面装饰，使阳光房而耐用，更美观。可以说铝包钢的阳光房是在本世纪初，符合中国国情的产物。其优点是强度较高，成本低。其缺点是施工周期较长，没有标准化。在施工过程中，不可控制因素较多，质量波动大。
The steel aluminum structure sunlight room in foreign countries is mainly because some sunlight rooms are too large, because of the high strength of steel and the convenience of welding, so the steel frame and aluminum welding rod are used. Build a big sunshine room. In China (especially in Shanghai), because the sun room is a new thing with high price, in order to reduce the cost, steel aluminum composite (aluminum clad steel sun room) is adopted. Steel as the main body of the structure meets the strength problem, while aluminum as the surface decoration, makes the sun room durable and more beautiful. It can be said that the aluminum clad steel sunshine room is in line with China's national conditions at the beginning of this century. Its advantages are high strength and low cost. Its disadvantage is long construction period and no standardization. In the construction process, there are many uncontrollable factors, and the quality fluctuates greatly.
