The aluminum and Fenglv aluminum material which is better suited for doors and windows
Al Feng is one of the ten famous material, certainly no problem. But Feng packaging is too thick, high cost. To do the doors and windows of the aluminum used to choose cost-effective, as a special material for the sale of aluminum, I have the following recommendations: 1. The window wheel is good, and the pressed glass should be durable and corrosion resistant. 2. doors and windows sealing performance better, 3. pages to be matched with materials, gauze or rust, and thickness and density better than 4. The cost performance is high, the surface treatment layer of the profile is electrophoresis, and the electrophoresis layer should be thick. 5. The mounting frame needs to be hit to the horizontal line.
Something out of the view of the cross section will feel dark, there are small manufacturers in the production of material without chromate treatment, resulting in the surface profile after a few years will appear off phenomenon, omitting some necessary process, will make the aluminum price per tonne lower than the high quality aluminum of several thousand dollars, now if in strict accordance with the national standard production then, aluminum doors and windows for the wall thickness below 1.2mm is used in the Beijing market is not allowed, curtain wall thickness to reach more than 1.4mm. Therefore, the selection of aluminum alloy profiles must choose large manufacturers, big brands. Some? Business should also take the responsibility, not to blindly save costs, and then choose materials, good brands. Home improvement is a day to spend thousands of days to see, and more attention to research is necessary.
PS: the selection of aluminum window into just half the decision factors, installation of doors and windows have a direct impact on the quality and life of your Windows, strictly speaking, the selection of aluminum should consider responding to a lot, such as climate, suitable for aluminum electrophoresis in coastal areas, because of its resistance to alkali corrosion inhibition; inland area selection spraying aluminum, its color is very rich in Beijing, multiselect bridge aluminum (considering energy saving and environmental protection, economic factors), domestic manufacturers of aluminum is uneven, price 2000~3000 yuan per ton is normal, because of the large manufacturers to something that is of good quality, with purity aluminum extrusion, the cross section of silver, customer service there are many security, the black heart of the small manufacturers (including some large manufacturers) will add different amounts of time in the production of aluminum, in order to offset part of the pure aluminum ingot, manufacturing
