Broken aluminum 85 means that the frame width is 8.5cm, and broken aluminum 108 means that the frame width is 10.8cm, but the section width can't tell everything, because the thickness of aluminum is also an important consideration. For example, the thickness of 1.6MM for 85 broken-bridge aluminum doors and windows is not necessarily cheaper than that of 1.4MM for 108 broken-bridge aluminum doors and windows. Under the same thickness, the price of 108 is naturally higher than 85.
Precautions:
The choice of aluminum thickness for high-rise balcony bridge closure depends on the different climate between north and south, so the demand for aluminum type and thickness for bridge closure will be different. The temperature in the north is low, so when people buy doors and windows, the first consideration is sealing and heat preservation. It is generally recommended to choose 60 series or 70 series.
Among them, 90% of the balconies sealed by broken bridge aluminum in Beijing are broken bridge aluminum 70 series windows. The climate in the south is warm and rainy, so the drainage performance should be considered when closing the balcony. Most of them will choose 90 series or 108 series of broken bridge aluminum screens, among which 108 series of screens are widely used.
