Dalian Yamei Doors and Windows Manufacturing Engineering Co., Ltd. was established in 2004 (formerly known as Dalian Zhongwang Industry & Trade Co., Ltd. and Dalian Zhongwang Architectural Decoration Engineering Co., Ltd.), adhering to the business philosophy of high starting point and high quality, introducing advanced European production equipment and raw materials to produce thermal break color composite aluminum energy-saving doors and windows, colored aluminum alloy doors and windows, and plastic-steel doors and windows, three major series of products. The company currently owns internationally advanced CNC cutting machines, corner crimping machines, and professional door and window processing and assembly production lines imported from Germany and Italy, mainly engaged in the development, design, production, installation, and maintenance of various mid-to-high-end building curtain walls and all types of doors and windows. The company is located in the high-tech industrial intensive development zone of Dalian, with a superior geographical location and convenient transportation. The production plant covers an area of 6,000 square meters, occupying approximately 10,000 square meters, with an annual production capacity of over 100,000 square meters of standard doors, windows, and curtain walls. Thermal break composite aluminum doors and windows are a new technology widely promoted in the European door and window industry in recent years, used as an energy-saving replacement for ordinary aluminum alloy and plastic-steel doors and windows. After adopting the thermal break cold bridge, it overcomes the inherent low energy efficiency due to the high thermal conductivity of ordinary aluminum alloys, responding to the international trend of advocating energy conservation and environmental protection; at the same time, it retains the important characteristics of aluminum alloys, such as easy extrusion, easy processing, corrosion resistance, aesthetics, sturdiness, durability, and light weight. When combined with insulating glass and sealing materials, it can be designed into highly efficient thermal insulation and heat preservation doors and windows. The company is committed to the development and introduction of new products, technologies, and materials, taking technological leadership as the main content of its development strategy, persistently launching new products and technologies to the market. With strict organizational management, advanced production processes, and high-quality after-sales service, the company practices the business tenet of "quality first, customer supreme."
