How much is Guangwei Aluminum per ton? How much is the aluminum window per square meter?

I know the price of aluminum alloy in Liang Dong, Zhejiang. Take Liang Dong Broken Bridge Aluminum as an example. White or colored Liang Dong broken bridge aluminum profile is 22,000 yuan/ton, dark champagne Liang Dong broken bridge aluminum profile is 23,000 yuan/ton, and light champagne Liang Dong broken bridge aluminum profile is 24,000 yuan/ton.
