Different brands and models have different prices. The price of aluminum alloy doors and windows is around 300~600 yuan. The quality of aluminum alloy doors and windows can be judged from the selection of raw materials (aluminum profiles), the quality of aluminum surface treatment and internal processing, and the price of aluminum alloy doors and windows.
There are 70 series and 90 series aluminum alloy sliding doors. The basic door opening height is 2 100, 2400, 2700 and 3000mm, and the basic door opening width is 1500, 1800, 2 100, 2700, 3000 and 3300.
There are 55 series, 60 series, 70 series, 90 series and 90-I series of sliding aluminum alloy windows. The basic opening heights are 900, 1200, 1400, 1500, 1800, 2100 mm; ; The basic window widths are 1200, 1500, 1800, 2 100, 2400, 2700 and 3000mm.

Matters needing attention
Look at the material The thickness, strength and oxide film of aluminum profiles for high-quality aluminum alloy doors and windows should meet the relevant national standards. The wall thickness of main stress rib of aluminum alloy window should be above 1.4 mm, the wall thickness of main stress rib of aluminum alloy door should be above 2.0 mm, the tensile strength should reach 157 Newton per square millimeter, the yield strength should reach 108 Newton per square millimeter, and the thickness of oxide film should be above.
Second, look at processing. High-quality aluminum alloy doors and windows, fine processing, exquisite installation, good sealing performance and convenient opening and closing. Inferior aluminum alloy doors and windows blindly adopt aluminum profile series and specifications, and the processing is shoddy. Saw instead of milling, not installed as required. Poor sealing performance, uncomfortable switch, not only air leakage and rain leakage, but also glass cracking. When encountering strong wind and external force, it is easy to scratch or touch the push-pull part or glass, damaging things and hurting people.
