There is basically no national standard for aluminum alloy profiles, but the state has specific industry specifications for architectural aluminum profiles, mainly for the thickness and material of the materials. The products produced by each aluminum alloy profile manufacturer are basically the same, but differ in the specific structure. But like the more general series, such as the national standard 50, 868, 90, these are basically the same. The 80 series and 60 series refer to the width of the aluminum alloy frame frame being 80 mm and 60 mm, respectively.
