Thermal insulation bridge aluminum alloy doors and windows cost accounting method
ã€China Aluminum Industry Network】 The principle of heat insulation broken bridge aluminum alloy is to penetrate the insulation strip in the middle of the aluminum profile and break the aluminum profile to form a broken bridge to effectively prevent heat conduction. In this way, door and window frame fans are made to be equipped with insulating glass, hardware, invisible screen windows, glass glue, styrofoam, sealing strips, etc., so that the portal windows manufactured by the processing are called broken bridge aluminum doors and windows.

First, the broken bridge aluminum: broken bridge aluminum finished product window a large proportion, take the bridge broken bridge aluminum, white or color broken bridge aluminum 22,000 yuan / ton, dark champagne bridge broken aluminum 23000 RMB/ton, light-colored champagne beam broken bridge aluminum 24,000 yuan/ton. 22,000 per ton of aluminum can be fixed window 130 square meters, flat window 100 square meters, flat door 70 square meters, 90 square meters sliding window.
Second, the hardware: the advantages and disadvantages of hardware accessories to a large extent affect the price of the window, such as the difference between the quality of imported hardware and domestic hardware is very large, imported hardware generally use 20,000 times without failure, the current market on the United States The high-end doors and windows of Chi and other hardware are imported from Germany. Some manufacturers use imported products at key locations and domestic products at the general site. Some windows produced by small manufacturers use domestic products. At least More than half cheaper. Domestic flat casement hardware 150 yuan/set, flat open top hung window hardware 280 yuan/set, flat door hardware 580; imported flat open window hardware 240 yuan/set, flat open top hung window hardware 360 ​​yuan/set, flat door hardware 720 yuan/set. Sliding window hardware 80 yuan sets.
Third, hollow glass: aluminum and aluminum doors and windows are used floating glass hollow glass, each square meter of 5 +12 +5 hollow glass is about 60 yuan / square meter. Hollow glass is made of two (or three) glass, high-strength and high-tightness composite adhesive, and the glass sheet is bonded to the aluminum alloy frame containing the desiccant to form a high-performance sound insulation and heat-insulating glass. Has good thermal and acoustic properties. It can not only meet the needs of modern office and home, but also effectively save energy.
Fourth, the invisible screen window: broken bridge aluminum doors and windows equipped with more hidden screens, invisible screens about the price of 150 yuan / sets, invisible screens are gauze can automatically rewind the screen window. Mainly ventilation and mosquito prevention. The frame is attached to the window frame. When it is used, the gauze is pulled down. When not in use, the gauze will automatically roll back into the box. Does not take up space, but also strong sealing.
V. Sealing treatment: The sealing treatment of doors and windows includes pressure sealing strips, styrofoam filling, glass glue, and sealant. The cost of these sealing treatments is approximately RMB 20/m2. The brand of seals is EPDM, the brand of styrofoam is Sanlays, the brand of glass glue is Dow Corning of the United States, and the brand of sealant is Dow Corning of the United States. These are good brands.
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.
VII. Transportation, Profit, Taxes: The transportation cost is about 2%, the profit is about 8%, and the tax is about 5%.
