Our family bought aluminum alloy doors and windows of the brand Palaide. You can consider it. I think it is very good and quite suitable for high-rise buildings because it is light in weight and high in strength. It is a very suitable choice for high-rise buildings. Our family lives on the top floor, which is considered a very high-rise building. At that time, I had been looking for doors and windows with such light texture. Fortunately, Parade did not disappoint me.
