1. What are the brands of broken bridge aluminum doors and windows?
1, broken bridge aluminum doors and windows brand Meichi: Beijing Meichi Building Materials Co., Ltd. was established in 1996, which is the first modern door and window enterprise in China to introduce German advanced technology and equipment. At present, the company has three mainstream materials: wood, aluminum and plastic, providing doors and windows products with different ethnic styles. The company was rated as one of the top ten brands of aluminum alloy doors and windows and the honorary title of China well-known trademark.
2. Sao Paulo, brand of broken bridge aluminum doors and windows: Sao Paulo Door Industry Co., Ltd. was established in 2003. After 10 years of development, it has become a comprehensive modern enterprise integrating R&D, production and sales. The company is mainly engaged in the production of aluminum alloy bedroom doors and craft solid wood doors, including kitchen and bathroom doors, balcony doors, partition doors and other products. It is an enterprise with complete varieties and brand influence in the industry.
3. Alumina Aluminum Industry, 199 1 was founded in Zhaoqing, and has been committed to the application of aluminum alloys in automobiles, heavy industry equipment, power engineering and other fields for many years. After years of unremitting efforts and persistence, alumina products have expanded from single aluminum profiles for building doors and windows and curtain walls to various industrial profiles, aerospace, rail transit, automobile manufacturing, electronic appliances, communication technology and it.
4. Xingfa Aluminum, 1984 was established in Foshan, which is one of the earliest aluminum alloy brands in China and one of the top ten aluminum alloy brands. Has been committed to the design and manufacture of high-precision, sharp aluminum extrusion profiles, with more than 800 national patents on aluminum alloy profiles. Products are mainly divided into two categories: building doors and windows curtain walls and industrial aluminum profiles. Through years of unremitting efforts and persistence in the development of the company's industry, covering industrial profiles and aerospace.
Second, the selection skills of broken bridge aluminum doors and windows
1, different profiles have different properties, so it is important to know this, mainly because the different thermal conductivity determines the energy consumption of doors and windows. When you choose a material, it is very important to design the profile. The heat insulation strip on the frame and the fan are not on the same side (close to outdoor or indoor), so that after installing the hardware fittings, the heat insulation strip is bypassed by the metal hardware fittings, so that the indoor and outdoor profiles are connected with each other, and the heat is quickly conducted, and so on.
2. Energy loss is mainly caused by convection, conduction and radiation. All of them should be considered, and glass mainly loses energy through thermal radiation, so when we choose the glass for building doors and windows, we must choose the glass reasonably to ensure the energy saving of the whole building. Take the southern region as an example. The southern region is hot in summer and warm in winter, with a long period of high temperature. In the choice of glass, we can't choose transparent glass with good lighting as in cold areas, but should choose low thermal reflection, such as thermal reflection coated insulating glass and Low-E insulating glass. Select glass with corresponding heat transfer coefficient and shading coefficient.
What are the brands of broken bridge aluminum doors and windows? The selection skills of broken aluminum doors and windows have been introduced in detail for everyone, and I hope you can use them as a reference. The above is Bian Xiao's detailed introduction.
