The aluminum alloy material adopts a hollow thin-wall combined section, which is light in weight and has a density of only one-third of the steel. The cross section has a high bending strength, and the finished door and window are durable and not easily deformed.
Good sealing directly affects the use of doors and windows and the consumption of energy. Generally, the sealing property refers to four aspects of airtightness, watertightness, heat insulation and sound insulation.
After the surface of the aluminum alloy is treated, it can be displayed in a variety of different colors, which can be arbitrarily selected and oxidized and polished. The frame of the sash can be made larger, with a larger area of glass, so that the indoor light is sufficient, so that the home is more layered.
Long service life, aluminum alloy doors and windows are highly resistant to corrosion, and the oxide layer is not easy to fade, does not fall off, does not need to be painted, and is easy to maintain. The door and window control system has a long service life.
Fire resistance: Class A insulation (1.5h for grade jia, 1.0h for grade B, 0.5h for grade C); Class B insulation for 0.5h, fire integrity of 1.0~3.0h; Class C fireproof for complete 1.0~3.0 h.
Sound insulation effect: has a good sound insulation effect.
