The demand for aluminum profiles is getting wider and wider, and aluminum profiles are used in all walks of life. It is obvious that the doors and windows used in our homes, how to choose aluminum profiles? What kind of aluminum profile is better for doors and windows?

How to choose aluminum profiles:

1. Look at the quotation of aluminum profiles. The material is different, the surface treatment is different, the wall thickness of the aluminum material is different, the quotation is different, and the difference is far. If the quotation is low, most of the secondary materials are recycled, and the wall thickness is too thin. The same is 1m of aluminum profiles. The material is only 1.2mm.

2. Look at the surface and section of the aluminum profile. If the surface and section are bright, it indicates that the alloy composition of the aluminum profile is high and relatively pure. If the section of the aluminum profile is black, or the surface color is not bright, at least it can be shown that the aluminum profile is made of recycled materials.

3. Look at the strength of the aluminum profile. There are two kinds of aluminum profiles, that is, the collision of good material and inferior material. The good material will not have too many knock marks, and the bad material will sink into a groove.

What kind of aluminum profile is good for doors and windows:

1. The window wheel should be better, and the rubber strip of the pressure glass should be resistant to old and corrosion;

2. The sealing performance of doors and windows is better;

3. The gauze page should be matched with the material, the gauze should not be rusted and the thickness and density should be good;

4. The cost performance is high, the surface treatment layer of the profile should be electrophoretic, and the electrophoresis layer should be thick;

5. The installation frame should be hit to the horizontal line.

The selection of aluminum profile brand products is only half of the determinants of the window. The installation of doors and windows also directly affects the quality and life of your doors and windows. Strictly speaking, there are many things that should be considered in the selection of aluminum profiles, such as climate reasons, coastal areas. Electrophoretic aluminum is suitable for selection because of its good corrosion resistance and alkali corrosion resistance; sprayed aluminum is often chosen in inland areas, and its color is very rich, and broken bridge aluminum is chosen in Beijing (considering energy conservation, environmental protection, and economic factors).

Domestic aluminum profile manufacturers are also uneven. The price difference of 2000~3000 yuan per ton is normal, but the products produced by large aluminum profile manufacturers are of good quality and will be extruded with pure aluminum ingots. Also guaranteed. And some black-hearted small aluminum profile manufacturers (not excluding larger aluminum profile manufacturers) will add varying amounts of scrap aluminum during production to offset some pure aluminum ingots. , and even some small aluminum profile manufacturers do not process the profiles during production, so that the surface of the aluminum profiles will fall off after a few years. Omitting some necessary processes will make the price of aluminum profiles low per ton. It costs several thousand yuan for high-quality aluminum materials. Now, if the production is strictly in accordance with the national standard, aluminum profiles for doors and windows with a wall thickness of less than 1.2mm are not allowed to be used in the Beijing market, and the wall thickness of curtain wall profiles must reach 1.4mm or more.
