Qingdao Kangjian Aluminium Industry: Building a globally trusted partner in aluminium profiles
In just three years since its establishment, Qingdao Kangjian Aluminum Industry Technology Co., Ltd. has rapidly expanded from its local market in Qingdao to the national and global markets. Our products not only cover the local area of Qingdao, but also reach deep into core domestic regions such as Anhui, Hebei, Tianjin, Hunan, Guangdong, Beijing and Jiangsu. Relying on the unique port and industrial advantages of Qingdao, we have successfully expanded into international high-end markets such as South Korea, Japan, the United States and Europe.
Against the trend of growth: Business volume and shipment volume have continued to rise, with the average annual growth rate of order delivery and output value reaching as high as 30%.
From industrial and architectural profiles to rail transit, aerospace, automotive, marine, and medical device applications — our product portfolio covers the full spectrum of aluminum extrusion demands with precision engineering and custom solutions.
Backed by Qingdao's world-class port infrastructure and deep global trade connections, Kangjian delivers premium aluminum profiles to clients in South Korea, Japan, the United States, Europe, and beyond — with reliable logistics and full export documentation support.
In Qingdao, a city by the Yellow Sea, a dream about high-end aluminum profiles quietly set sail in 2022. Several founders were well aware of the vigorous demand in this industrial hotspot, but they regretted the lack of domestic high-end aluminum extrusion capabilities. This regret kindled their determination to fill the void.
Qingdao, backed by a vast domestic market and facing the blue international trade waterway, has endowed Kangjian with a unique "dual-sea layout". Kangjian Aluminium Industry came into being, determined to serve the world.
"Producing high-end aluminum materials and serving global customers" — this is not only an idea but also a principle deeply ingrained in our very veins. With cutting-edge equipment, strict quality control and unremitting innovation, Kangjian has turned its promises into reality.
The giant gantry cranes in Nordic ports are firmly established thanks to Kangjian's high-strength corrosion-resistant aluminum materials. On the drawings of the world's top projects, the logo of "KANGJIAN ALUMINIUM" shines brightly.
Setting sail from Qingdao, Kangjian embraces the world with the openness of the sea and carries the future with the tenacity of aluminum. Every precision profile silently tells us: "Made in China" is forging the industrial backbone that connects the world here.
