Why is broken bridge aluminum expensive and cheap

Click:748 Times:2018-06-15

In the process of consumption, people will have such a consumption concept: the higher the price, the better, the more quantity the better, and the more materials the better. Therefore, when consumers buy broken bridge aluminum doors and windows, they will take it for granted that the thicker the aluminum wall, the better the quality of the product if it exceeds the national standard, but in fact it is not the case.

In the process of consumption, people will have such a consumption concept: the higher the price, the better, the more quantity the better, and the more materials the better. Therefore, when consumers buy broken bridge aluminum doors and windows, they will take it for granted that the thicker the aluminum wall, the better the quality of the product if it exceeds the national standard, but in fact it is not the case. According to industry insiders: The national standard for product wall thickness is to ensure product safety and function, and is set in accordance with energy conservation and environmental protection requirements. It is not that the thicker the product wall, the better the product quality.


       Therefore, excessively thick profile wall thickness cannot guarantee the air-tightness and water-tightness of the product, and the product quality is high, and it will inevitably lead to excessive waste of resources. Moreover, there are more consumables for products that are too thick than products that meet the national standard, which will inevitably bring excessive product prices and bring unnecessary economic burdens to consumers. Therefore, aluminum products that meet the requirements of national standards can be called good products.


       So what should be done to buy "good quality and low price" broken bridge aluminum doors and windows?


      Broken bridge aluminum doors and windows


      1. The wall thickness of the profile is qualified


 


      Generally, door and window manufacturers in home improvement shopping malls mostly choose products with high yield, that is, products with relatively thin wall thickness to reduce the cost. Some small manufacturers produce 1.2mm-1.3mm thick ones that are lower than the national standard, but the national standard rule thickness should be greater than or equal to 1.4mm; broken bridge aluminum profiles are generally divided into 60 series (6 cm) and 70 series (7 cm). The quality of broken bridge aluminum doors and windows does not depend on which series of profiles are selected, but mainly depends on the material, wall thickness, heat insulation strips, and processing technology of the broken bridge aluminum doors and windows. The residential area is relatively quiet and the windows are not very large. It is sufficient to choose 60 series of profiles. If the residential area is facing the street and has floor-to-ceiling windows, which require high sealing, sound insulation and heat preservation, you can choose 70 series of profiles.


 


       2. Seal planning


 


      Different brand profiles have different sealing plans. There are three, four, five, six, seven, eight, nine, and even ten seal plans. However, the raw materials produced by the top ten broken bridge aluminum profile factories in China are all externally opened with 2 sealing strips and internally opened with 3 sealing strips. In order to meet the needs of consumers, many domestic broken bridge aluminum manufacturers produce large-sized broken bridges. Aluminum doors and windows, to increase the internal track that can wear rubber strips. In this way, broken bridge aluminum merchants can wear rubber strips by themselves, so that the so-called series of seals appear. In theory, the more seals, the better the heat preservation effect.


    


      3. Supporting accessories


 


When consulting the price of broken bridge aluminum doors and windows, you must ask whether it includes the cost of supporting materials such as beams, columns, casement hardware, positioners, gauze, waterproof glue, and styrofoam. Because many Broken Bridge aluminum merchants have quotation traps, in order to attract customers, they first quote the unit price lower, and then the merchants compensate for the difference by charging various auxiliary materials.


The cost of these auxiliary materials is usually several thousand yuan, and the total price is not cheap at all.


        4. Add subframe


        Sub-frame is also called attached frame and protective frame. Door and window frames are fixed on the wall and used for equipment doors and windows, generally used for 70 series and below profiles. If the window needs to be covered with a window cover (window pass), tiles need to be pasted around the window, and the top of the window needs a ceiling, then additional frames are required. Because the profile frame of 70 series and below is relatively narrow, it will hinder the opening of doors and windows. The advantage of the equipment sub-frame is that there will be gaps at both ends of the door and window equipment, which is not beautiful, and after adding the sub-frame, all the gaps can be covered. The function is equivalent to the dumb opening of the door and window, but the addition of the sub-frame requires a separate additional charge. Cost.


        In the process of consumption, people will have such a consumption concept: the higher the price, the better, the more quantity the better, and the more materials the better. Therefore, when consumers buy broken bridge aluminum doors and windows, they will take it for granted that the thicker the aluminum wall, the better the quality of the product if it exceeds the national standard, but in fact it is not the case. According to industry insiders: The national standard for product wall thickness is to ensure product safety and function, and is set in accordance with energy conservation and environmental protection requirements. It is not that the thicker the product wall thickness, the better the product quality. Because of the excessively thick profile wall thickness, the air tightness and water tightness of the product cannot be guaranteed, and the product quality is high, which will inevitably lead to excessive waste of resources. Moreover, there are more consumables for products that are too thick than products that meet the national standard, which will inevitably bring excessive product prices and bring unnecessary economic burdens to consumers. Therefore, aluminum products that meet the requirements of national standards can be called good products.
