At the production base of GDJM Aluminum Technology Group, Hay Think inspected the melting and casting workshop, extrusion workshop, surface treatment workshop, finished product warehouse, and other supporting workshops and R&D inspection areas in turn.
The GDJM production base covers an area of nearly 700,000 square meters (over 1,200 mu), and was officially put into operation in early 2008. The base has world-class production and research and development equipment. It has accredited qualifications such as nationally accredited laboratories, national enterprise technology centers, post-doctoral research workstations, technology research institutes, and door and window system testing centers. Currently, GDJM's annual R&D investment accounts for more than 3% of sales revenue.
In the architectural aluminum display area, curtain wall products that are widely used in urban buildings, and many world-marked engineering cases, all use GDJM products.
Among the 10 tallest skyscrapers in the world, 5 use GDJM products; among the 67 super high-rise buildings above 300 meters in the country, 24 use GDJM products. The Great Hall of the People of China, National Museum, CCTV New Building, AIIB Headquarters Building, Hong Kong-Zhuhai-Macao Bridge Artificial Island Building, Huawei R&D Building, California Federal Government Building, Tokyo Toranomon Modern City Main Tower (the tallest building in Japan), GDJM products are used in Dubai Tower, UAE.
In the door and window system display area, we have experienced the watertightness, airtightness, heat insulation, cold insulation, and sound insulation of doors and windows. In the watertight experience zone, the outdoor simulated torrential rain (rainfall reaches 250mm/d), but there is no leakage of wind or water inside. In the airtight experience area, the outdoor simulates strong winds above level 12 (wind speed reaches 25m/s), the windows do not move, and there is no air leakage near the indoor windows. In addition, high-performance doors and windows such as multifunctional electric lifting sliding doors, translation sliding doors, anti-mosquito sliding doors, haze-removing sliding windows, dust-proof side-hung doors, sun-shading external windows, fire-resistant windows and other high-performance doors and windows also impressed the investigating experts.
The door and window system company under the GDJM Group has developed more than 80 door and window system products in 6 major systems, providing products and technical services for large real estate developers such as Poly, Country Garden, Vanke, Longhu, and China Resources. The company researches and develops the design requirements of building doors and windows according to the environmental characteristics of different climatic regions. The application scope has covered the five major climate regions of the country: severely cold regions, cold regions, hot summer and cold winter regions, hot summer and warm winter regions, and mild regions.
In the industrial material exhibition area, we watched a variety of industrial aluminum products. In recent years, relevant state departments have advocated "substituting aluminum for steel, aluminum for copper, aluminum for plastic, and aluminum for wood", which has accelerated the application of aluminum in various industrial fields. In terms of industrial materials, GDJM self-developed products have been widely used in many subdivisions, such as computer panels and mobile phone frames; urban rail and subway power bus bars; UHV power equipment; helicopter main rotor splint profiles; supply to Huawei and Ericsson 5G communication base station filters and waveguides of other enterprises; new energy vehicle charging pile profiles; new energy passenger car body profiles, etc.
Lightweight and environmental protection are important directions for the development of automotive materials today, and aluminum alloy products are one of the most promising lightweight materials for automotive weight reduction. The aluminum profile new energy passenger car body with a new high-strength and tough structure independently developed by GDJM has been applied to FAW Jiefang and BYD because of its high strength, light weight, good corrosion resistance, easy processing and forming, and good welding performance. , Great Wall, Dongfeng, Xiaopeng, Geely, Honda, Tesla and other auto brands. In addition to the automotive field, Jianmei products are also used in aerospace equipment aluminum parts, rail transit equipment aluminum parts, and cultural, educational and sports equipment aluminum parts.
Since its establishment in 1993, GDJM currently has more than 5,000 employees and an annual production capacity of 450,000 tons. It has participated in the formulation and revision of 180 national and industrial standards, including 2 international standards. Jianmei has won the title of "China Famous Brand" twice, and successively won the "Guangdong Provincial Government Quality Award" and the National Highest Quality Award. The second "China Quality Award" has become the only aluminum profile enterprise in China that has won the country's highest quality award.
Products are widely used in construction, electronic communication hardware, building templates, machinery manufacturing, solar panels, all-aluminum bicycles and other fields.
