How much is a square meter for a balcony in Nanjing?

The price of balcony sealing in Nanjing depends on the size of profiles you need, including hardware screens and double-layer tempered glass. Prices are different in different regions. As far as Nanjing is concerned, the balcony seal is 600- 1500/ m2, and the balcony window is the first protection of the house. It takes more than 10 years, but it can't be cheap. You should choose a regular company. I hope it helps you.
