Recently, Xiaobian found that there are windows and doors manufacturers on the Internet claiming that the full price is 330 yuan per square meter. I really don't know whether the broken bridge aluminum doors and windows are made of aluminum? Or is there something fishy about it? More than 300 yuan of broken bridge aluminum doors and windows can only cover the cost of aluminum materials and production, including glass costs, hardware screen costs, auxiliary materials costs, installation and transportation and enterprise profits. Do you dare to buy such cheap broken bridge aluminum doors and windows? There's a hundred percent of it.

 Production color and cost calculation of aluminum doors and windows

How much is the cost of broken bridge aluminum doors and windows?

1. First of all, the cost of bridge breaking aluminum profiles is the big end. Take the bridge aluminum 70 series as an example, the average cost per square meter is 260 yuan, and the cost of using 5 + 24 + 5 insulating glass is 70 yuan per square meter, which accounts for 330 yuan per square meter.

2. The cost of sealant strip: some manufacturers use cheap EPDM tape, the cost per square meter is 25 yuan, while liefan's broken bridge aluminum doors and windows all use automobile grade TPE tape, the cost is 45 yuan per square meter; there is also the cost of glass glue waterproof glue, some manufacturers use glass glue on the glass, the outer wall uses waterproof sealant, and liefan's broken bridge aluminum doors and windows all use glass glue With the foam rubber, the cost is 35 yuan per square meter. In this way, the cost of sealing strip and glue is 80 yuan.

3. Processing, manufacturing and installation costs: the processing cost of bridge broken aluminum doors and windows is generally 25 yuan per square meter, and the installation cost is 35 yuan per square meter, totaling 60 yuan.

In this way, the cost price of 70 series of bridge broken aluminum doors and windows should be 470 yuan, which does not include the normal loss, water and electricity costs of the factory, employee wages and enterprise profits. Therefore, the factory price of 70 series of bridge broken aluminum doors and windows will not be less than 500 yuan per square meter, which still does not include the prices of hardware and screen windows.

Therefore, when the prices of some doors and windows are exorbitant, there must be something fishy about it. No one will make a loss. What you buy will never sell well. Choosing a regular and reputable manufacturer is the king's way.

About the factory color of broken bridge aluminum doors and windows:

 Production color and cost calculation of aluminum doors and windows

The main colors of broken bridge aluminum doors and windows are white and champagne. Among them, light champagne color is the most popular color among consumers. Light champagne color will not appear dark at home, while deep champagne will cause poor light and make windows feel black when installed at home. Therefore, light champagne bridge broken aluminum doors and windows are most popular with owners. At the same time, because the champagne color is aluminum type of electrophoresis process If some consumers are perfectionists and can't accept the color difference of the broken bridge aluminum doors and windows in the color of champagne, the manufacturers of the aluminum alloy doors and windows recommend that the white broken bridge aluminum doors and windows should be white.

The main problem is the color difference of products. The influence of extrusion process on oxidation coloring is mainly the influence of die design, extrusion temperature, extrusion speed and cooling mode on the surface state and microstructure uniformity of extruded profiles. The die design should be able to make the feed fully blended, otherwise it is easy to have bright (dark) band defects, and color separation may appear on the same profile; meanwhile, the die state and extrusion lines on the profile surface also affect the oxidation coloring. Different extrusion temperature, speed, cooling mode and cooling time will lead to uneven structure and color difference.
