Aluminium extrusion has become one of the most important downstream segments in the global aluminium value chain, feeding demand from construction, transportation, industrial manufacturing, renewable energy and electric mobility. As demand becomes increasingly diversified across these applications, the scale and sophistication of a country’s aluminium extrusion industry have become an important indicator of its downstream aluminium footprint.
China sits firmly at the centre of this market. AL Circle’s extrusion industry study put global extrusion capacity at around 49 million tonnes per year in 2023, with China accounting for nearly 64 per cent with a 30-million-tonne annual capacity, or about 31.07 million tonnes. Global extrusion consumption was estimated at 31.5 million tonnes, of which China represented about 66 per cent.
According to AL Circle’s estimates, China’s extrusion consumption increased from 20.94 million tonnes in 2023 to 21.47 million tonnes in 2024, projected to reach around 27.52 million tonnes by 2030.
Against this backdrop, China’s large and diverse pool of aluminium downstream companies is particularly important to watch.
1. Beijing Only Aluminium Industry Co., Ltd
It operates as an integrated aluminium processor, with activities spanning casting, die manufacturing, extrusion, surface treatment and fabrication. Its portfolio covers architectural and industrial profiles as well as applications in automotive lightweighting, rail transit, road transport, power and containers. The company reports more than 60 extrusion production lines across a wide range of capacities.

The company also operates anodising, powder-coating, fluorocarbon, wood-grain, electrophoresis, polishing and other surface-treatment lines. Its intelligent manufacturing expansion is designed to integrate the wider aluminium-processing chain.
4. Jilin Jusheng Light Alloy Co., Ltd
Jilin Jusheng is primarily a high-precision aluminium sheet, strip and foil producer rather than a conventional extrusion specialist. The company forms part of Liaoyuan’s effort to develop a high-precision aluminium and rail-transit industrial cluster.
Solutions offered to customers
Its product portfolio includes aluminium plate and strip, can-lid material and aluminium foil, with applications extending into automotive and new-energy-related markets. This makes the company particularly relevant to aluminium-intensive battery, transportation and lightweighting supply chains.
Technologies used
Jusheng’s technology focus is centred on high-precision rolled aluminium processing rather than extrusion. Its production platform is aimed at achieving the material consistency and dimensional control required for specialised sheet, strip and foil applications.
5. Shandong Huajian Aluminium Co., Ltd
Situated in Linqu, Shandong, Huajian Aluminium has built an integrated aluminium-profile manufacturing and processing platform. The company operates six production plants and six industrial parks, with activities covering aluminium profile production and value-added processing.
Solutions offered to customers
Huajian serves architectural and industrial markets with aluminium profiles, while its downstream portfolio extends to aluminium formwork, scaffolding and other value-added products.

Its equipment base includes a 10,000-tonne extrusion line and advanced processing and testing equipment sourced from countries including Germany, Switzerland, Israel, France and the US.
6. Shanxi Bada Magnesium Co., Ltd
Despite its name and strong magnesium focus, Shanxi Bada operates across a broader non-ferrous materials platform. The company supplies high-performance metallic materials to aerospace, automotive, electronics, oil and gas, construction and specialised markets, with aluminium included alongside magnesium in its material portfolio.
Solutions offered to customers
Bada’s model is closer to a one-stop materials supplier, offering raw ingots and billets through semi-fabricated products and secondary processing. Its services include extrusion, casting, rolling, machining, welding, anodising and coating.
Technologies used
Its processing platform combines extrusion with casting, rolling and machining technologies. The company also provides downstream fabrication and surface treatment, allowing customers to obtain finished or semi-finished lightweight-metal components through a single supply chain.
7. Sinbro Materials
Sinbro Materials, a division of Jinan Youyue New Material Technology Co., Ltd, operates primarily as an aluminium distributor and processing supplier rather than a clearly established primary extrusion manufacturer. Its business is built around inventory, processing and global order fulfilment.
Solutions offered to customers
The company supplies aluminium plates, sheets, bars, rods and structural profiles in different alloys, sizes and shapes. Its offering is particularly notable for marine-grade and mould-grade aluminium, including specialised aluminium mould plate.
Technologies used
Sinbro’s competitive proposition appears to centre more on material sourcing, processing, stock management and distribution than on large-scale extrusion technology. This makes it relevant to downstream buyers seeking customised aluminium material and rapid supply rather than extrusion capacity itself.
8. Wan Star Aluminum Industry Co., Ltd
It has built a broad aluminium production and processing portfolio over more than two decades. Its production base covers more than 160,000 square metres and the company reports annual production capacity of approximately 1.2 million tonnes.

Its patent record includes processes for deep-drawing aluminium alloy strip and stabilising aluminium alloy materials, highlighting its focus on specialised material processing.
10. Zhejiang Kaisite Technology Co., Ltd
Kaisite occupies a different position in the extrusion value chain: it specialises in the design and manufacture of aluminium extrusion dies rather than operating primarily as a profile producer. The company says it has 14 years of manufacturing experience and supplies tooling to domestic and international aluminium processors.
Solutions offered to customers
Its tooling portfolio covers architectural profiles, industrial profiles, automotive lightweight components, heat sinks, high-speed rail materials and photovoltaic solar frames. More recently, its solutions have included complex dies for EV battery trays, cooling plates and frames.
Technologies used
Kaisite combines extrusion simulation and CAE analysis with high-precision CNC machining, vacuum quenching and vacuum tempering. Its multi-cavity and specialised internal-structure dies are designed to control metal flow and achieve tight dimensional tolerances, including complex EV and automotive profiles.
As China’s aluminium extrusion industry accelerates, its aluminium extrusion ecosystem is worth watching not just for its 30-million-tonne annual output capacity, but for the range of technologies and downstream solutions emerging across its aluminium extrusion manufacturers.
