The principle of the heat-insulated bridge aluminum alloy is to insert a heat-insulating strip in the middle of the aluminum profile to break the aluminum profile to form a broken bridge, effectively preventing heat conduction. In this way, the door and window frame fan is assembled, and the insulating glass, the hardware, the invisible screen window, the glass glue, the styrofoam, the sealing strip and the like are assembled, and the portal window processed by the processing is called the broken aluminum door and window.
First, the broken bridge aluminum profile: the large proportion of the finished window of the broken aluminum profile. Take the Dongliang broken bridge aluminum for white or color dongliang broken bridge aluminum profile 22,000 yuan / ton, dark champagne dongliang broken bridge aluminum profile 23,000 yuan / ton, light-colored champagne dongliang broken bridge aluminum profile 24000 yuan / ton. 22,000 aluminum per ton can be fixed window 130 square meters, casement window 100 square meters, swing door 70 square meters, sliding window 90 square meters.
Second, hardware: The advantages and disadvantages of hardware accessories have greatly affected the price of windows. For example, the difference in quality between imported hardware and domestic hardware is very large. Imported hardware generally uses 20,000 times without failure. At present, the hardware of high-end doors and windows such as Meritor is imported from Germany, and some manufacturers use imported parts in key parts. Products, general parts use domestic products; some small manufacturers produce windows using domestic products, then the performance is at least half cheaper than the price. Domestic cased window hardware 150 yuan / set, flat open hanging window hardware 280 yuan / set, swing door hardware 580 imported casement window hardware 240 yuan / set, swing open hanging window hardware 360 ​​yuan / set, swing door hardware 720 Yuan / set. Sliding window hardware 80 yuan set.
3. Insulating glass: The doors and windows of the broken aluminum are all hollow glass with float method. The 5+12+5 insulating glass per square meter is about 60 yuan / square meter. A high-performance, high-viscosity composite adhesive is used to bond a glass sheet to an aluminum alloy frame containing a desiccant to produce a high-performance sound-insulating glass. Good insulation and sound insulation. It can meet the needs of modern office and home, and effectively save energy.
Fourth, invisible screens: Broken bridge aluminum doors and windows with the most hidden screen window. The approximate price of the invisible screen window is 150 yuan / the invisible screen screen gauze can automatically rewind the screen window. The main frame for ventilation and anti-mosquito is attached to the window frame. When it is used, the gauze is pulled down. When not in use, the gauze will automatically rewind into the net box. It does not take up space and is highly sealed.
V. Sealing treatment: The sealing treatment of doors and windows includes pressure sealing strips, filling styrofoam, glass glue, sealing glue and so on. The cost of these sealing treatments is about 20 yuan / square meter sealing strip brand is EPDM, the brand of styrofoam is Sanles, the brand of glass glue is Dow Corning, the brand of sealant is Dow Corning, these are Good brand.
Sixth, labor costs: the production cost of broken aluminum doors and windows is 25 yuan / square meter. The installation cost is 35 yuan square meters.
7. Transportation, profit, tax: The transportation cost is about 2%. The profit is about 8%. The tax is about 5%.
